How is heat transmitted?
Heat is transmitted in three ways. They are
-
Conduction
-
Convection
-
Radiation
Conduction: Conduction is the process of heat transfer that happens in solid. The gases and liquid are poor conductors of heat.
Convection: Convection is the process of heat transfer that happens in liquid and gas.
Radiation: Radiation is the process of the transmission of heat energy from the sun. This type of transmission of heat energy does not require any medium.
