Question

In ____________ heat is transmitted mainly by convection.

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.
4. Transfer of heat in liquids mainly happens because of convection.

Hence, In liquid heat is transmitted mainly by convection.
