Question

A satellite in space exchanges heat with its surroundings in which mode of heat transfer

Answer 1

heat exchange by radiation please mark as brainleist

Answer 2

The mode or mechanism of transfer of heat in this case is taking place through Radiation.

• Radiation is the mode of transfer of heat that can take place without any medium present or without the aid of particles of any medium.
• In space, there is no atmosphere and hence there is no medium or particles through which heat can be transferred.
• Radiation occurs in space when a satellite body has a temperature greater than its absolute temperature of zero, and thus its heat or thermal energy is given off from that body in the form of radiation.
• This heat energy or radiation is in the form of electromagnetic radiation.
• The conduction and convection process of heat transfer is not possible here because in space there is no medium for heat transfer and these two processes can only take place when there is a medium.
• Hence, the correct answer here is the radiation mode of heat transfer.
