Samacheer Kalvi 5th Science Guide Term 1 Chapter 3 Energy

VII. Answer in detail:

Question 1.
Explain the types of Mechanical energy.
Answer:
Energy possessed by an object due its position is called mechanical energy.
Mechanical energy can be classified into two;

  • Kinetic energy
  • Potential energy

a) Kinetic energy: Energy possessed by a moving objectis known as kinetic energy. It is also known as energy of motion.
Eg: Moving car, cricket ball bowled by a player, bullet coming out of a gun.

b) Potential energy: Energy possessed by an object which is at rest is known as potential energy. It is also known as stores energy of position.
Eg: Object lifted above, stone in the stretched rubber, water in the dam.

Question 2.
Explain Conservation of energy.
Answer:
Energy cannot be created cannot be destroyed also. It is changed from one form to another form or transferred from one object to another object. Examples for conservation of energy in our daily life are :

1. Water dam :

  • Water stored in water dams posseses potential energy.
  • When water falls down, potential energy of water is converted, into kinetic energy.
  • Kinetic energy of water rotates the turbines and electric energy is generated.

2. Electrical appliances:

  • Electrical energy is used in many domestic appliances such as electric stove, iron box and fan.
  • Electric energy flows into the coil in the devices.
  • As current flows, it heats up the coil.
  • With the help of this heat energy, we do many useful works.
  • Thus, electrical energy is converted into heat energy.
  • Electical energy is converted to mechanical energy in fan, light enrgy in bulb and sound energy in computer.

3. Driving a car:

  • We use fuel in the form of petrol or diesel or gas to run vehicles.
  • When this fuel burns in the engine, chemical energy is converted into heat energy.
  • Burning fuel produces hot gases which pushes the piston in the engine to move the vehicle.
  • Thus heat energy is converted into mechanical energy.

The Case of The Missing water Summary in English and Tamil

The tank in Divya’s village was almost dry. Ammachi began to pray for rain. Amma collected all the buckets and pots and vessels in the house and filled them up.. “We need to store as much water as we can,” she said. Appa collected tools to dig a little deeper. “We just need enough until the rains arrive,” he said.

திவ்யாவின் கிராமத்திலிருந்த குளம் பெரும்பாலும் வறண்டு விட்டது. அம்மாச்சி மமை வரவேண்டுமென பிரார்க்கனை செய்தார். வீட்டிலிருந்த வாளிகள், பானைகள், பாத்திரங்கள் எல்லாவற்றையும் எடுத்து, அவற்றில் நீரை நிரப்பி
வைத்தாள் அம்மா. “நம்மால் முடிந்த அளவுக்கு தண்ணீரை சேமிக்க வேண்டிய தேவை ஏற்பட்டுவிட்டது”, என்றாள் அம்மா. கொஞ்சம் ஆழமாகத் தோண்டு வதற்கான கருவிகளை அப்பா சேகரித்தார். “மழை வரும் வரையில் நமக்கு இது தேவை”, என்றார் அவர்.

Divya got out her notebook and pencil. She put on her thinking cap and followed her parents to the tank. She examined the tank bed closely. It was cracked and dusty.

திவ்யா ‘ தனது நோட்டு புத்தகத்தையும் பென்சிலையும் எடுத்துக் கொண்டாள். தனது பெற்றோரை பின்தொடர்ந்தபடி குளத்திற்குச் சென்றாள். வெகு அருகிலிருந்தபடி குளத்தை அவள் ஆய்வு செய்தாள். நிலத்தில் பிளவு ஏற்பட்டு, தூசி படிந்திருந்தது.

Divya wondered, “Where did the water in the tank go? Did it run away? Was it stolen? This is a mystery!” Divya loved solving mysteries: Like the time Ammachi couldn’t find her reading glasses. Divya had found them in her book, marking the page she was reading. “I’ll find that water,” Divya muttered to herself.

திவ்யா ஆச்சர்யப்பட்டாள். “குளத்திலிருந்த தண்ணீர் எங்கே போனது? அது ஓடிவிட்டதா? திருடப்பட்டுவிட்டதா? இது ஒரு மர்மம்”, என்றாள். மர்மங்களுக்கு தீர்வு காண்பதை திவ்யா விரும்பினாள். படிப்பதற்கான கண் கண்ணாடியை அம்மாச்சி கண்டுபிடிக்க முடியாமல் போன சமயத்தில் நடந்ததைப் போல.

அவருடைய புத்தகத்தில், படித்த பக்கத்தை குறிப்பிட வேண்டி, அது வைக்கப்பட்டிருந்ததை திவ்யா கண்டுபிடித்துக் கொடுத்தாள். “அந்த தண்ணீரையும் நான் கண்டுபிடிப்பேன்,” என திவ்யா தனக்குள் முணுமுணுத்துக் கொண்டாள்.

Divya walked to the other side of the tank, past dead fish and dried reeds. “Do you know where the water could have gone?” Divya asked a fisherman. “Downstream?” the fisherman suggested. Divya followed the dry stream bed down the hill. At the bottom was another tank. It had lots of goats, but no water.

திவ்யா குளத்தின் மறுகரைக்கு நடந்தாள். இறந்து போன மீன்களையும், காய்ந்து போன நாணல்களையும் கடந்தாள். “தண்ணீ ர் எங்கே போயிருக்க முடியுமென உங்களுக்கு தெரியுமா?” என ஒரு மீனவரைதிவ்யா கேட்டாள்.

“கீழ்மட்டத்திற்கு போயிருக்கலாம்,” என்றார் மீனவர். குன்றின் அடியிலிருந்த, வறண்டு போன நீரோடையில் திவ்யா நடந்தாள். கீழே இன்னொரு குளம் இருந்தது. அங்கு பல ஆடுகள் மேய்ந்த படி இருந்தன, ஆனால் நீர் இல்லை.

Divya asked the goatherd, “Do you know where the water might be?” “Upstream,” the goatherd suggested. I “That’s where I came from,” Divya said. “No water there.” “Further up, then?” the goatherd said. “That’s where your water comes from.”

திவ்யா ஆடு மேய்ப்பவரிடம், “தண்ணீ ர் எங்கே போயிற்று என உங்களுக்குத் தெரியுமா?” என கேட்டாள். ஆடுமேய்ப்பவர், “மேல் மட்டத்திற்கு போயிருக்கலாம்” என்றார். “அங்கிருந்து தான் நான் வருகிறேன், அங்கு தண்ணீர் இல்லை” என்றாள் திவ்யா. “அதற்கும் மேலே. அங்கிருந்துதான் தண்ணீர் வருகிறது”, என்றார் ஆடு மேய்ப்ப வர்.

Divya climbed up to the tank. Then she climbed up some more to a tank further up the hill. There was no water, no birds. There was only one person there. “Rani, I can’t find any water. Any idea where it’s gone?” Divya called to her. She knew Rani from school.

“Downstream,” Rani called back. Divya was suddenly angry. She stomped her foot. “No!” she shouted. “It’s not. I
have searched and searched. It’s not upstream or downstream. Got it?”.

திவ்யா குளத்தை நோக்கி குன்றின் மேலே ஏறினாள். அங்கு இருந்த ஒரு குளத்தில் தண்ணீ ரும் இல்லை, பறவைகளும் இல்லை. ஒரே ஒரு பெண் மட்டும் இருந்தாள். “ராணி, தண்ணீரையே பார்க்க முடியவில்லை. அது எங்கே போயிற்று என்று ஏதாவது ஐடியா இருக்கிறதா?”

என திவ்யா அவளைக் கேட்டாள். பள்ளியிலிருந்தே ராணியை அவளுக்குத் தெரியும். “கீழ் மட்டத்தில்”, என்றாள் ராணி. திவ்யா திடீரென கோபப்பட்டாள். தரையை காலால் தட்டினாள்.

“இல்லை” என கூச்சலிட்டாள். “அங்கே இல்லை. நானும் தான் தேடினேன்-தேடினேன். அது மேல்மட்டத்திலும் இல்லை, கீழ்மட்டத்திலும் இல்லை. புரிந்ததா?”

“How about up there?” Rani suggested. Divya and Rani looked up at the sky.” The sun glared back at them. Everything was white-hot and dusty. “No,” they agreed together. “No water there. Divya collapsed into the boat with Rani and gnawed on a lotus stem. She was hot and tired.

அது இன்னும் உயரே சென்றிருக்கலாம்,” என்றாள் ராணி. திவ்யாவும், ராணியும் வானத்தைப் பார்த்தனர். சூரியன் அவர்களின் மீது ஒளியை பாய்ச்சியது. எல்லாமே வெள்ளையாக-வெப்பமாகவும், தூசியுடனும் இருந்தன. “இல்லை, அங்கே தண்ணீர் இல்லை”, அவர்கள் இருவருமே ஒரு சேர ஒப்புக் கொண்டனர். திவ்யா, ராணியுடன் படகில் சாய்ந்தபடி, ஒரு தாமரைத் தண்டை கடித்தாள். அவள் உடம்பு வெப்பத்தால் தகித்தது. அவள் களைப்படைந்தாள்.

“Manju’s parents left the village, “Divya said. “They went to the city” where they have water. Maybe we should all go.” “You go,” Rani snapped. “No one asked you to be here.” “Fine,” Divya said. And she stomped back home. But it wasn’t fine! There was still no water, still no rain.

மஞ்சுவின் பெற்றோர் இந்த கிராமத்தை விட்டுச் சென்று விட்டனர். நகரத்துக்குப் போய் விட்டனர். அங்கு அவர்களுக்கு தண்ணீ ர் கிடைக்கும். நாம் எல்லோரும் போக வேண்டி வரலாம்”, என்றாள் திவ்யா. “நீபோ, இங்கேயே இருக்கவேண்டுமென உன்னை
யாரும் கேட்டுக் கொள்ளப் போவதில்லை”, என்றாள் ராணி. “நல்லது” என்றாள் திவ்யா. அவள் வீட்டுக்குத் திரும்பினாள் ஆனால் அங்கு சூழ்நிலை சரியில்லை. இன்னும் அங்கு தண்ணீர் இல்லை, மழையும் இல்லை.

The next day, Divya brushed her teeth with muddy tank water in a tiny glass. “Thooo!” she spat. In school, the class was half-empty. More families had left the area. She missed all her friends! In the middle of Environmental Studies class, she turned and ran out of school. She ran and ran until she was panting. She finally sat at the side of the road.

அடுத்த நாள். சேறுகலந்த குளத்து நீரை ஒரு சிறிய கிளாஸில் வைத்துக் கொண்டு, திவ்யா பல் துலக்கினாள். “த்தூ!” என அவள் துப்பினாள். பள்ளியில் பாதி வகுப்பு காலியாக இருந்தது. அந்தப் பகுதியிலிருந்து மேலும் பல குடும்பங்கள் சென்று விட்டிருந்தனர்.

அவள் தன் எல்லா நண்பர்களையும் இழந்தாள். வகுப்பில், சுற்றுச்சூழல் பாடத்தின் நடுவே, அவள் எழுந்து, பள்ளியை விட்டு ஓடினாள். மூச்சிறைக்கும் வரை அவள் ஓடினாள். இறுதியில், சாலையின் ஒரு புறத்தில் அவள் அமர்ந்தாள்.

“I have to find the water!” she huffed. “Can I help?” said a voice. It was Rani who had seen Divya running away” from school. Divya beamed. “Yes!” “We have to do this properly,” Rani said. “Like real Sanitary Engineers.” “Like who…?” Divya asked. “Sanitary Engineers build pipes and tanks and drains. I am going to be one when I grow up,” Rani said. Divya and Rani decided to draw a map of their village and all its tanks and streams, showing all the places where the water might have flowed.

தண்ணீர் எங்கே போனது என நான் கண்டுபிடிக்க வேண்டும்”, என்று ஒரு வித கோபத்துடன் “உனக்கு உதவட்டுமா”, என்றது ஒரு குரல், அது ராணி தான். பள்ளியிலிருந்து திவ்யா ஓடிவந்ததை அவள் பார்த்தாள். “சரி”, என்றாள் திவ்யா.”சுகாதாரப் பொறியாளர்களைப் போல, நாம் இதை சரியாகச் செய்ய வேண்டும்”, என்றாள் ராணி. “யார் அவர்கள்?”, என்று திவ்யா கேட்டாள்.

“குழாய்கள், தொட்டிகள், வடிகால் வாய்க்கால்களை கட்டுகிறார்களே அவர்கள் தான். நான்பெரியவளாக வளர்ந்த பிறகு சுகாதாரப் பொறியாளராவேன்,” என்றாள் ராணி. அவர்களின் கிராமத்தின் வரைபடத்தை அவர்கள் இருவரும் வரைய தீர்மானித்தனர். மேலும் தண்ணீர் செல்லக்கூடிய வழித்தடங்கள், குளங்கள், ஓடைகள் எல்லாவற்றையும் வரைபடத்தில் குறிக்கவும் முடிவு செய்தனர்.

Where could the water possibly have gone? Finally, they sat back and pored over the map. “We haven’t seen that tank yet,” Divya pointed to one of the tanks they had drawn. “Let’s go,” Rani agreed. Divya and Rani began climbing up the hill. The stream here was dry as well.

தண்ணீ ர் எங்கே போயிருக்க கூடும்? இறுதியாக, அவர்கள் தரையில் அமர்ந்து, வரைபடத்தை கூர்ந்து ஆராயத்தொடங்கினர். “அந்தக் குளத்தை இதுவரை நாம் பார்க்கவில்லை, அவர்கள் வரைந்த குளங்களில் ஒன்றை சுட்டிக்காட்டியபடி, திவ்யா இவ்வாறு கூறினாள். “நாம் போகலாம்”, ராணி சம்மதித்தாள். ஏறத் தொடங்கினர். அந்த ஓடையும் வறண்டு திவ்யாவும், ராணியும் அந்தக் குன்றின் மீது போயிருந்தது.

“Maybe we shouldn’t have missed school. This tank is probably dry as well,” Rani said sadly. When they reached the tank, Divya” and Rani realised they were wrong. This tank was full! Rani pointed at a small pump at the end of the lake. There was a tanker just below the bund, collecting water as it flowed. A man stood by, guiding the tanker. “Mystery solved,” said Divya angrily.

நாம் பள்ளிக்குச் செல்வதை தவற விட்டிருக்கக் கூடாது. இந்தக் குளமும் வறண்டிருக்கிறது”, என்றாள் ராணி வருத்தமாக. குளத்தை அவர்கள் அடைந்தபோது, திவ்யா, ராணி இருவருமே தங்களது யூகம் தவறு என உணர்ந்த னர். அந்தக் குளத்தில் தண்ணீ ர் நிரம்பியிருந்தது.

அங்கு ஏரியின் முடிவில் ஒரு சிறு பம்ப் இருந்ததை ராணி சுட்டிக்காட்டினாள். கரைக்குக் கீழே ஒரு டேங்கர் (நீர் ஏற்றிச் செல்லும் வாகனம்) இருந்தது. அதில் தண்ணீர் நிரப்பப்பட்டுக் கொண்டிருந்தது. அதனருகில் ஒரு மனிதன் நின்றிருந்தான். “மர்மம் தீர்க்கப்பட்டது”, என்றாள் திவ்யா கோபத்துடன்.

“Where are you taking our water?” Divya wanted to know. “The city,” the man said. “I need to supply nine-thousand litres today!” “That’s not fair!” Rani said. The man shrugged, “That’s how it is.” “My friend is a Sanitary Engineer, Divya yelled. “She knows what’s fair.” The man laughed.” Sanitary Engineer it seems! You’re just children!” Rani said quietly, “Yes, but I know you can’t just take our water away.”

“எங்கள் தண்ணீ ரை எங்கே எடுத்துப் போகிறீர்?” என்று திவ்யா கேட்டாள். “நகரத்திற்கு, இன்றைக்கு நான் 9,000 லிட்டர் தண்ணீ ரை சப்ளை செய்தாக வேண்டுமே”, என்றான் அந்த மனிதன். “அது நியாயமல்ல”, என்றாள் ராணி.” “அது அப்படித்தான்,” என்றான் அவன் தன் தோள்பட்டையை உயர்த்தியபடி, “என் நண்பர் ஒரு சுகாதாரப் பொறியாளர்.

அவருக்கு எது நியாயமெனத் தெரியும்,” என்று திவ்யா சத்தமிட்டாள். அந்த மனிதன் சிரித்தான். “துப்புரவாளர் என்று தோன்றுகிறது. நீங்கள் எல்லாம் குழந்தைகள்தான்,” என்றான் அவன். “ஆம். ஆனால், நீங்கள் எங்கள் தண்ணீ ரை எடுத்துச் செல்ல முடியாது,” என்று ராணி அமைதியாகச் சொன்னாள்.

“Go home,” the man said. “You can’t change anything!” Divya had an idea. She hugged the pump. “You can’t turn it on now!” Rani ran up to hug the pump too. “Hey!” said the man. Now he was really angry. “Just go home,” he said.

“வீட்டுக்குப் போங்கள், உங்கள் இருவரால் எதையும் மாற்றிடவிட முடியாது”, என்றான் அவன். திவ்யாவுக்கு ஒரு யோசனை தோன்றியது. அவள் அந்த “பம்ப்”-ஐ கட்டி அணைத்துக் கொண்டாள். “இப்போது உங்களால் இந்த பம்ப்-ஐ திருப்ப முடியாது.” ராணியும் ஓடிச்சென்று’ பம்ப்-ஐ அணைத்துக் கொண்டாள். இப்போது அந்த மனிதன் உண்மையிலேயே கோபப்பட்டான். “வீட்டிற்குப் போய் விடுங்கள்”, என்றான்.

That was when the clouds broke, and rain poured. “The ‘monsoon is here!” Divya shouted. “I’m going home, even if you aren’t, the tanker man said. It rained and rained. WOOSH, the bund overflowed, and the stream rushed down, splashing them.

அப்போது மேகங்கள் உடைந்து, மழை பெய்தது. “பருவமழை இங்கே ஆரம்பம்”, திவ்யா சத்தமிட்டாள். “நீங்கள் போகாவிட்டாலும், நான் வீட்டிற்குப் போகிறேன்”, என்று அந்த டேங்கர் மனிதன் கூறினான். மழை தொடர்ந்து பெய்தது. ஊஷ், குளம் நிரம்பி வழிந்தது. நீரோடையில் தண்ணீர் பாய்ந்து அவர்கள் மீது, தெறித்தபடி, கீழ்நோக்கி ஓடியது.

“The water has been found! Mystery solved!” Divya said. “WOOOOOO!” They yowled with joy.

“தண்ணீர் கண்டுபிடிக்கப்பட்டுள்ளது! மர்மம் தீர்ந்தது”, என்றாள் திவ்யா. “ஊ…” அவர்கள் மகிழ்ச்சியுடன் குரல் எழுப்பினர்.
