First Law of Thermodynamics

The increase in internal energy of a system is the sum of the heat supplied tothe system and the work done on the system

Internal energy

The sum of kinetic energy and potential energy associated with random motions of particles of the system

Specific heat capacity

The amount of heat required to produce a unit change in temperature per unit mass of the substance

Specific latent heat of fusion

The amount of heat required to change a unit mass of the substance from solid to liquid without a change in temperature

Specific latent heat of vapourisation

The amount of heat required to change a unit mass of the substance from liquid to gas without a change in temperature

Isobaric

Pressure constant

Isochoric

Volume constant

Isothermal

Temperature constant

Adiabatic

No heat exchange (heat supplied is 0) Only work done changes the internal energy
