Modes of Heat Transfer

Q. What do you mean by insolation?

1. Incoming solar radiation
2. Outgoing solar radiation
3. Increase in temperature
4. Decrease in temperature

Q.

1. The transfer of heat through vertical movement of air is called advection.
2. Horizontal movement of the air is relatively more important than the vertical movement for the heating and cooling of the atmosphere.
3. Seasonal local wind ‘Loo’ is the outcome of the advection process.

Q. What is conduction?

1. The mechanism of transfer of heat between two adjacent parts of a body because of same temperature.
2. The mechanism of transfer of heat between two adjacent parts of a body because of difference in humidity.
3. The mechanism of transfer of heat between two adjacent parts of a body because of their temperature difference.
4. The mechanism of transfer of energy between two adjacent parts of a body because of their difference in state.

Q. How is the heat budget of the Earth maintained?

1. With balance of solar radiation between insolation and terrestrial radiation.
2. With the balance of solar radiation between advection and conduction.
3. With the balance of solar radiation between advection and insolation.
4. With the balance of solar radiation between convection and conduction.
