Describe briefly difference between conduction, convection, and radiation.

The three types of heat transfer are conduction convection and radiation. Explanation:

Heat transfer happens only when there is said to be a temperature difference. (i.e) heat transfer occurs with a higher temperature region to a lower temperature region. Heat is transferred usually via some medium in the case of convection and conduction whereas in the radiation no medium is required ( i.e it take place in a vacuum ).  Conduction is a type of heat transfer that is mainly a character for the conducting and semiconducting solid material.  Convection is the heat transfer method that usually takes place in the liquids and gases.  Radiation is the heat transfer process in which heat is transferred via infrared or electromagnetic waves.
