Transfer of Energy and Heat

There are three ways of transferring heat: conduction, convection and
radiation. Conduction is the transfer of heat between objects that are in
physical contact. Transference of heat from fire to an aluminum pot when
heating some water is an example of conduction. The transfer
of heat between an object and its environment, through fluid motion is
called convection. For example, the spreading of heat through vapor or
smoke. Radiation is the transfer of heat by means of electromagnetic
waves. The transfer of heat energy from Sun to Earth is through
radiation. This type of heat transfer does not require any media, neither
does it require the two objects to be in touch with each other.
