Question: What about cooling?

Cooling is the opposite of heating, but there is not an opposite of heat energy.

When an object cools it is because heat has flowed out of the object.

Heat only flows out of an object if it is in contact with a colder object (or it is in colder surroundings).

Since cold objects make us feel colder, it is very common for students to mistake the process of heat flow for the process of cold flow.

NB. There is no such thing as cold flowing into an object to make it colder!
