Which change in an object will increase its thermal energy? A. A decrease in either mass or temperature
B. An increase in either mass or velocity
C. A decrease in either mass or velocity
D. An increase in either mass or temperature

Heat decreases the thermal energy of an object as energy moves to the air. Heat causes the thermal energy of the object to increase as energy moves from the warmer air to the colder object. Heat has no effect on thermal energy, but it increases the potential energy of an object.
