Convection
Explanation:
Convection is form of heat transfer by which heat moves through liquid and circulates due to density differences.
There are three major forms of heat transfer:
- Conduction is form of heat transfer that involves contact between two bodies in which collision between their molecules caused heat exchange from the hot body to the cold one.
- Radiation is a form of heat transfer that does not involve contact. It involves the use of electromagnetic waves of different forms.
- Convection occurs in fluids in which heat transfers as a result of movement of molecules of the medium from one point to the other. The hotter body becomes lighter and rises whereas the colder ones sinks.
