Which definition of heat is most scientifically accurate?

A) the movement of thermal energy from one place to another

B) the temperature of the thermal energy in an object

C) how hot or cold something is

D) a measure of the thermal energy in matter

The correct option is A) the movement of thermal energy from one place to another.

Explanation:

Many people describe heat in reference to anything which feels warm. But the scientific definitions of heat describes it as the transfer of energy from a warmer object to a cooler object. It is defined as the flow of energy between two systems. Heat energy or thermal energy is transferred by the bouncing of atoms with each other. The more the energy in the atoms of an object, the more will be the thermal energy.
