We are asked to determine the type of heat transfer in each of the cases.

The possible processes of heat transfer are:

Conduction: the heat that is transferred by the vibration of particle in the same medium-

Convection: The heat that is transferred due to the movement of a fluid{

Radiation: The heat that is transferred through electromagnetic waves.

1. The heat from hot water transferring to metal sppons ins process in which heat is transferred from a fluid to a solid medium, this type of heat transfer is convection.

2. Formation of sea breeze. This is an effect cause by difference in temperature between the air in the surface of the sea and the air above, therefore, the heat is transferred due to the movemen of the air and therefore this is convection.

3. Ligh and heat coming from the sun comes in the form of electromagnetic waves therefore this is radiation.

4. Heat when holding tongs. This heat is transmitted through the same medium, in this case, the tongs and is therefore conduction.

5. The formatio of thunderstorms are due to difference in the the movement of moisture and air in the atmosphere therefore this is convection

6. The heat felt near a bonefire is due to electromegnetic waves produces in the combustion of the bonefire and hterefore it is radiation.

7. Land breeze is due to difference in temperature caused by the movement of air therfore, this is convection.

8. Tropical depressions and are caused by the movement of air and moisture near the surface of the ocean, therefore, this is convection.

9. A pot sutting on a stove undergoes conduction

10. Aluminum foil used for wrapping food is the heat that is tranferred due to the vibration of the molecules of aluminum therefore, this is conduction.
