Explain different ways of heat exchange with examples?

The fundamental modes of heat transfer are:

Advection

Advection is the transport mechanism of afluidsubstance orconservedproperty from one location to another, depending onmotionandmomentum.

Conductionordiffusion

The transfer of energy between objects that are in physical contact.Thermal conductivityis the property of a material to conduct heat and evaluated primarily in terms ofFourier's Lawfor heat conduction.

Convection

The transfer of energy between an object and its environment, due to fluid motion. The average temperature, is a reference for evaluating properties related to convective heat transfer.

Radiation

The transfer of energy from the movement ofcharged particleswithin atoms is

converted toelectromagnetic radiation.
