What is specific heat ? What is latent heat and its type ?

SPECIFIC HEAT :- It is defined as the amount of heat required to raise a unit mass of a substance through a unit rise in temperature.
                   
HEAT CAPACITY :- The product of mass and specific heat is called Heat capacity.

LATENT HEAT :- It is the amount of heat transfer required to cause a phase change in unit mass of a substance at a constant pressure and temperature.

Types of Latent heat :-

1) Latent heat of fusion
2) Latent heat of vaporisation
3) Latent heat of sublimation

1) Latent heat of fusion :- It is the amount of heat transferred to melt unit mass of solid substance into liquid substance or to freeze unit mass of liquid to solid.

2) Latent heat of vaporisation :- It is the amount of heat required to vaporise unit mass of liquid into vapour , or condense unit mass of vapour into liquid.

3) Latent heat of sublimation :- is the amount of heat transferred to convert unit mass of solid to vapour or vice versa.
