Question

.When does the thermal energy of a body increase? *

A) When the K.E, of the body decreases.

B) When the P.E. of the body increases

C) When the mechanical energy of the body decreases

D) When the K.E. of molecules in a body increases


​

Answer 1

Answer:

D when the k.e of molecules in a body increases...

Answer 2

Answer:

c is the is ans

Explanation:

When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
