Which statement correctly describes heat energy flow?

• As an object cools, energy is absorbed by the object.

• As heat energy is lost by an object, the temperature of the object increases.

• Heat energy flows from the colder object to the warmer object.

• If a cold object touches a hot object, there is no flow of heat energy.

• If a hot object touches a cold object, heat flows from the hot object to the cold object.
