Solution
The correct option is D all of above
The movement of heat from one body to another (gas, liquid, solid, or combinations thereof) by means of radiation, convection, or conduction is called heat transfer. Conduction, transfer of heat or electricity through a substance, resulting from a difference in temperature between different parts of the substance, in the case of heat. Convection depends on the fact that, in general, fluids expand when heated and thus undergo a decrease in density. The energy radiated by solids, liquids, and gases in the form of electromagnetic waves as a result of their temperature. Also known as thermal radiation.
