How do liquids and gas transfer heat?

Convection

Explanation:

heat: Can be defined as a form of energy flow due to temperature difference. The unit of heat is is Joules.

Method of heat transfer: There are three method of heat transfer and they are, conduction, convection and radiation.

Conduction : This is a process by which heat is transferred along a metal object.

Convection : This is a process by which heat energy is transferred in a fluid (liquid or gas).

Radiation : This is the process by which heat is transfer from one source to another without heating the intervening medium.

Therefore Liquids and gases transfer heat by convection.
