Question

Is heat a form of energy?
A) True
B) False

Answer 1

Hint:- The movement of tiny particles such as atoms, ions and molecules in solid, liquid or gaseous substances, results in the formation of heat. This can be transferred from one object to another. Heat is the transformation due to the difference between temperature of two objects.

Step by Step Solution: -
Heat can be defined as the total amount of energy which is formed by the movement of tiny particles such as atoms, ions and molecules in solid, liquid or gaseous substances. Whenever there is a difference of temperature between two objects the heat can be transferred between two bodies, so this energy can be transferred from one object to another. So, it is a form of energy.

The heat energy flows from the warmer object or substance to the object which is cold. The transfer of heat energy can occur by the direct contact, by radiation between two bodies, by way of an intermediate fluid or by using the barrier which is impermeable to the matter.
The movement of atoms, molecules or ions is equally distributed among all degrees of freedom. It is different from work because work is confined to one or more specific degrees of freedom such as those of the center of mass.
Hence, from the above, we can conclude that heat is a form of energy.

Therefore, the correct option is (A).

Note: - Convection transfers heat energy from gases and liquids, conduction transfers energy in solids and in the process of transfer of heat energy through radiations there is no requirement of particles to carry heat energy.
