# Pressure exerted by an ideal gas molecule is given by the expression

The pressure exerted by an ideal gas molecule is given as P = MC2/3V

where M is the mass of the gas,

C is the r.m.s velocity of the gas molecules, and

V is the volume of the gas

### IDEAL GAS LAW

The pressure, P, volume V, and temperature T of an ideal gas are related by a simple formula called the ideal gas law. Ideal gases are defined as having molecules of negligible size with an average molar kinetic energy depends only on temperature.

PV = nRT

Where

• P is the pressure of the gas,
• V is the volume taken up by the gas
• T is the temperature of the gas,
• R is the gas constant, and
• n is the number of moles of the gas.
