Question

Convection is the main mode of transfer of heat in _____________.

Answer 1

1. Heat can be defined as the energy which flows from the body of a higher temperature to a body of lower temperature.
2. In liquid, conduction is not a successful mode of heat transfer as inter-molecular distance is larger compared to solid.
3. Due to the large inter-molecular distance, the chance of collision is less compared to that of a solid.
   Hence, Convection is the main mode of transfer of heat in liquid.
