Question

TIL 1. How will you prove that heat is a form of energy
​

Answer 1

Explanation:

when we cook food in pressure cooker by placing itover a stove the heat energy changes water to steam steam in turn lift the weight on the top of the lid and whistles. this lifting of weight suggest that heat is a form of energy which is capable of doing work .

Answer 2

Answer:

Here's your answer.

Explanation:

Heat is a form of energy that can be transferred from one object to another or even created at the expense of the loss of other forms of energy. To review, the temperature is a measure of the ability of a substance, or more generally of any physical system, to transfer heat energy to another physical system. when we cook food in a pressure cooker by placing itover a stove the heat energy changes water to steam, in turn, lift the weight on the top of the lid and whistles. this lifting of weight suggests that heat is a form of energy that is capable of doing work. Even when the water is not hot enough it contains some energy and is not enough to lift the weight at the top. But later the water forms steam it is able to lift the weight. It means that water gets energy due to it. This tells us that heat is a form of energy. It is simply the potential energy stored in the bonds that hold particles within the object together. Heat or thermal energy is the form this energy possesses when it is being transferred between systems and surroundings. There is nothing material about heat. It is neither a substance nor a fluid that is conserved.
