Question

The transfer of heat that occurs in liquids and gases is called _______.

Answer 1

1. The transfer of heat from the hotter part of an object to the colder part by the actual movement of its particles is called convection.
2. Convection occurs in liquids and gases, where the particles are free to move from one place to another.
3. The movement of particles during convection forms convection currents in liquids and gases.

Hence, the transfer of heat that occurs in liquids and gases is called convection.
