Detailed explanation-1: -The transfer of heat by radiation involves the carrying of energy from an origin to the space surrounding it. The energy is carried by electromagnetic waves and does not involve the movement or the interaction of matter.

Detailed explanation-2: -Another way to transfer heat is by conduction, which does not involve any motion of a substance, but rather is a transfer of energy within a substance (or between substances in contact).

Detailed explanation-3: -Radiation is the transfer of heat by electromagnetic waves. Note that, unlike conduction or convection, heat transfer by radiation does not need any matter to help with the transfer.

Detailed explanation-4: -Both conduction and convection require matter to transfer heat. If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower system.

Detailed explanation-5: -Conduction. Heat conduction occurs by transfer of vibrational energy between molecules, or movement of free electrons. Conduction is particularly important with metals and occurs without observable movement of matter. Convection.
