Question

Describe briefly difference between conduction, convection, and radiation.

Answer 1

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.
