Thermal energy depends on an object s

a. mass.

b. phase (sold, liquid, or gas).

c. temperature.

d. all of the above

Thermal energy depends on an object’s mass, phase and temperature. The answer is letter D. The movement of an object depends on how heavy it is. The heavier the object, the slower it moves. It is dependent on the phase because of the space the object it moves. It moves a lot when it is in gas phase. And most importantly, it increases its movement if temperature is added.
