Question

6.
Compare the three modes of heat transfer.​

Answer 1

There are three modes of heat transfer namely conduction, convection and radiation.

Conduction : Conduction refers to the heat transfer that occurs across the medium. Medium can be solid or a fluid.

Convection : Convection refers to the heat transfer that will occur between a surface and a moving fluid when they are at different temperatures.

Radiation : In radiation, in the absence of intervening medium, there is net heat transfer between two surfaces at different temperatures in the form of electromagnetic waves.

Answer 2

MODES OF HEAT TRANSFER:

There are three modes of heat transfer namely Conduction, Convection and radiation.

1. Conduction: Conduction refers to the heat transfer that occurs across the medium. Medium can be solid or a fluid.
2. Convection: Convection refers to the heat transfer that will occur between surface and moving fluid when they are at different temperatures.
3. Radiation: In radiation, the absence of intervening medium there is net heat transfer between two surfaces at different temperatures in the form of electromagnetic waves.
