Question

(A) Define Heat energy
(B) How does heat energy flow from one body to another body?

Answer 1

Hint We are given here to define heat energy and then to discuss how heat flows from one body to another body. Thus, we will define heat energy taking into account the simulation of it. Then we will discuss how it can be transferred from one body to the other.

Complete Step By Step Solution
1. Heat energy can be referred to as the result of the movement of microscopic or tiny particles called ions in solids, liquids and gases. It can also be referred to the energy generated when the atoms, molecules or ions of a material get excited and collide with each other.
2. Heat will naturally flow from a body with higher temperature to a body with lower temperature. The basic three phenomenon of heat transfer are:
3. Conduction: It is the phenomenon of transfer of heat when an atom in a material gets excited and collides with the adjacent atom and in turn makes it excited and this process continues in turn transferring the energy from one atom to the other and in turn to another body in some cases. For example: Heating of a rod when we apply heat on only one side of it.
4. Convection: It is the phenomenon in which the warmer current of a part in a body moves towards the colder region and in turn the cold current comes to the warmer region and gets heated up. For example: Boiling of water.
5. Radiation: It is the phenomenon in which a body radiates the heat energy into the surroundings and another body captures the heat in turn getting the heat transferred.

Note All the phenomenon of the transfer of heat comes as a result of the excitement of the atoms. This makes it clear that the heat energy is dissipated through a body and attained by other by making the subatomic particles in it getting excited.
