Question

What happens to an object as its thermal energy increases?

It cools down.


It heats up.


It doesn't change.


It might freeze.

Answer 1

It heats up.

Step-by-step explanation:

Because thermal energy is based off the temperature of an object and 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 increase.
