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
