Question

At the microscopic scale, how will a hot body be different from a cold body?​

Answer 1

Answer: Hope that helped

Explanation:

Heat should not be confused with temperature but they can directly be related. Temperature is the measure of a degree of hotness or coldness.

For chemical compounds, heat depends on the speed of atoms and molecules. It is the internal energy of compound due to the virtue of molecular motion of particles contained in them. Faster is the motion of atoms and molecules, higher is the heat transfer and higher would be the temperature. Similarly, slower is the motion of atoms and molecules, lesser is the heat transfer and lower would be the temperature. Thus, heat is the result of the microscopic motion of particles.

Heat can also change the total internal energy of the system. The entry or exit of heat increases or decreases the internal energy of the body.
