Question
Which of the following heat transfer method is used on the surface of the Sun?
- Conduction
- Convection
- Radiation
- None of these
Hint:
Convection is the process of heat transfer in which transfer of heat energy occurs by the mass movement of molecules of the fluids like gases and liquids.
The correct answer is: Convection
- Heat is a form of energy which is transferred from an object with a higher temperature to that with a lower temperature.
- The heat transfer rate of a body due to convection is directly proportional to the temperature difference between the body and its surroundings.
- For the transfer of heat from the sun to the earth, the energy emitted from the sun has to travel through the vacuum.
