How does heat flow?

Heat is

• the transfer of thermal energy from one object to another.

• the transfer of chemical energy from one object to another.

• the transfer of food.

• the transfer of water.

Thermal energy usually travels from

• an object with a lower temperature to an object with a higher temperature.

• an object with a higher temperature to an object with a lower temperature.

• an object with a higher volume to an object with a lower volume.

• an object with a lower volume to an object witha higher volume.
