Question

5.A material medium is required for transfer of heat by the processof radiation.
please ask me it is true or false​

Answer 1

Answer:

The transfer of heat by radiation does not require any medium. It can take place whether a medium is present or not. When we sit i n front of a room heater, we get heat by this process. A hot utensil kept away from the flame cools down as it transfers heat to the surroundings by radiation.
