Question

When does the thermal energy of a body increase?


A
When the K.E. of the body decreases
loader
B
When the P.E. of the body increases
loader
C
When the mechanical energy of the body decreases
loader
D
When the K.E. of molecules in a body increases
loader

Solution

The correct option is D When the K.E. of molecules in a body increases
The thermal energy of a body increases due to the increase in the kinetic energy of the body.
Thermal Energy = Kinetic Energy + Potential Energy
Again, Kinetic energy = $$\cfrac{1}{2}kT$$. Therefore, if T increases, kinetic energy also increases, as a result thermal energy also increases.
