The properties of a perfect gas are: A perfect gas comprises of an large number of indistinguishable particles. The volume possessed by the particles themselves is negligible contrasted with the volume involved by the gas. The molecules comply with Newton’s laws of motion, and they move in irregular or random movement 

A perfect gas can be explained by three state factors or variables: absolute pressure (P), volume (V), and temperature which is absolute (T). The connection between them might be deduced from theory of kinetic and is known as the number of moles (n). R = universal gas constant which is equal to 8.3145 J/mol K. N as the number of molecules or particles.
