Question

what do u think is only cause of heat transfer ​

Answer 1

There are three ways of heat transfer - Conduction, convection and radiation.

1. Conduction - Transfer of heat through solid medium.

2. Example - conduction of heat in iron rod.

3. Convection - Transfer of heat in fluid medium.

4. Fluid medium includes liquids and gases.

5. Example - Heating of water.

6. Radiation - This mode of heat transfer doesn't require any medium for energy transfer.

7. It can occur in vacuum.

8. Example - Transfer of solar radiation from sun to earth.

Answer 2

Explanation:

• The one thing that is most important for any type of heat transfer is the medium through which the heat is transferring.
• So far different kind of heat transfers are happening, they are Radiation Convection or Conduction.
• And each medium has certain transfer of heat requirement and lack of that medium, then the stoppage of transfer happening.
• To a certain extent this phenomenon is used in thermal flask which cancel out the medium of transfer of heat, thereby keeping things warm or cold as they are.
