## Compressibility factor

Compressibility factor of gases is a thermodynamic property which is used to modify the ideal gas equation for real gases.
For Ideal gases, Ideal gas equation...

## Work done in thermodynamic processes

A system can reach from state A to state B following different paths. These paths followed by a system while undergoing a change of state, are termed as...

## Universal Gas Constant

The behaviour of an Ideal gas is described by the following equation,
PV = nRT
where,
P = Pressure (bar, atmosphere, Pa)
V = Gaseous volume (m3, cm3)
n =...

## Specific heat ratio / Adiabatic index

Heat capacity of a system can be defined as the quantum of heat required to increase the temperature of the system by unity.

Specific heat is a property of...

## Gas Compression

Gas compression is done to increase the pressure of the gas, this is accompanied by change of state of the gas which means change in temperature and volume of...
