How does heat affect the thermal energy of an object that is colder than the air that surrounds it?
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.
Heat is not related to thermal energy, so it cannot affect the thermal energy of an object.
