Sensible heat as name that heat you can feel.

Latent Heat :- Latent Heat is that heat which changes the phase of substance or system without change of temperature.

Total Heat of System :- Latent Heat + Sensible Heat Total heat expressed in Ton of Refrigeration.

MODE OF HEAT TRANSFER

Heat transfer takes place by three methods:

1)Conduction 2) Convection 3) Radiation
