occurs in fluids
Explanation:
Convection is a mode of heat transfer that occurs in fluids.
There are three types of heat transfer:
conduction convection and radiation
- Conduction is a mode of heat transfer that involves an actual contact between the molecules of the medium. It occurs mostly in solids
- Radiation uses electromagnetic waves to transfer heat between two bodies or places. It does not require a material medium. The heat of the sun reaches us by radiation.
- Convection is a mode of heat transfer in fluids. It involves the density differences between hot and cold liquids and gases.
- Water boils by convection currents.
