Question
Define radiation.The transfer of heat:through a solidby the flow of a liquid or gasfrom hot objects but not cold objectsby the movement of waves, not particles
Solution
Radiation is a process of heat transfer that does not require a physical medium and can occur in a vacuum. It is the transfer of energy by electromagnetic waves. These waves carry energy away from the emitting object, for instance, the sun emits heat and light energy that reaches earth through radiation. This process does not require a solid, liquid, or gas to transfer heat, and it can occur from both hot and cold objects. Unlike conduction and convection, which involve the movement of particles, radiation involves the movement of waves.
