How is thermal energy transferred between two objects that are at different temperatures?

• The object at a lower temperature pulls heat energy from the warmer object.

• Heat flows from the warmer object to the cooler object until they reach the same temperature.

• Heat flows from the object that has more thermal energy to the object that has less thermal energy.

• Heat flows back and forth between the two objects until they reach the same temperature.
