Question

explain five uses of thermal energy in our daily life​

Answer 1

Answer:

1. The steam has a high specific heat ( more than the water) , It is used to carry a lot of heat energy at high pressures to run the rail engines or the rotors in AC generators .
2. The water in the swimming pool remains cool even in summer and the people enjoy a lot staying inside the pool , Because the water has high specific heat .
3. We use the heat in cooking , We use the utensils for making tea or coffee , or cooking vegetables or rice .
4. The heat is used as a simple yet effective way to manage the pain and the joint or muscular stiffness , The deep and penetrating heat does not only relieve the pain but also it enhances the recovery process .
5. Photosynthesis: In plants, light energy from sun converts to heat energy and gets trapped in the Importance of heatleaves to form carbohydrates.
6. Water cycle: Water cycle is a phenomenon responsible for the rain and life on earth. When the heat from the sun contacts water on the earth, it evaporates by forming water vapor. This evaporation which mostly happens from the oceans to form the clouds. These vaporous clouds, in turn, reach the land through the sky, get cooled and cause rains. The rainwater collects in pools, ponds, rivers, etc. and the excess returns to seas and ocean. This cycle is called a water cycle and this happens due to heat gain and heat loss (cooling) mechanism. When the water gets heated, it evaporates from the earth and when the clouds get cooled, it causes rain on the planet. So heat from the sun is responsible for showers and life on earth.
7. Drying: Drying is done by removal of water from surfaces. This is possible by wind currents and even vacuum. But the most common method is by use of heat. Sun’s heat helps in drying clothes, soil and any other wet surfaces. Transferring heat to moist clothes set the water molecules into motion thereby they easily move away into the air leaving the cloth dry.
