Question

Explain why the pressure exerted by a gas does not depend on the type of the gas.

Answer 1

Explanation: the pressure exerted by a gas does not depend on the type of the gas because pressure is a physical force its has not chemical composition.

So, pressure depends upon the numbers of molecules of the gas because gas molecules collide with the wall of the vessel. They exert force on the wall and we know the pressure is force applied per unit area .

According to Gay - Lussac's law,  the temperature of the gas is direct proportional to the pressure  at a constant volume.

Answer 2

The pressure exerted by a gas depends on the number of gas particles present, according to the Kinetic Molecular Theory of gases. Other factors like volume of the particles or the intermolecular forces between molecules are assumed zero. So 50 particles of Helium gas exerts the same pressure of 50 particles of Oxygen gas.
