Question

We receive the heat from the Sun through transfer of heat known as ________

Answer 1

1. The transfer of heat from a hot object to a cool object without any intermediate medium is called radiation.
2. For example, Sun is far away from the earth and there is a vacuum in between.
3. Hence, we cannot receive the heat from the sun through conduction or convection (both processes need a medium for heat transfer).
4. We receive heat from the sun through another process called radiation.

Hence, we receive the heat from the Sun through transfer of heat known as radiation.
