Deviation of Gases from Ideal Behavior

These gases which obey the Boyle’s law, Charles’s law or general gas equation are said to be ideal. In order to check the ideality of a gas, we can plot a graph between “n =  = Z”, and thepressure of the gas for one mole of gas. In the case of ideal gas, a straight line is expected parallel to ...

Kinetic Molecular Theory of Gases

KINETIC MOLECULAR THEORY OF GASES The gas laws give us the general behavior of gases. These laws are based on experimental observations and they are almost independent of the nature of gas. When we want to discuss the behavior of gases quantitatively, then we should appreciate the kinetic theory of gases given by Bernoulli in 1738. He was the first ...

Collision Diameter, Collision Frequency, Collision Number and Mean Free Path

Collision Diameter, Collision Frequency, Collision Number and Mean Free Path In the kinetic molecular theory of gases, we come to know that the molecules of a gas aremoving randomly, colliding among themselves and with the walls of the vessel. During the collisions, they suffer a change in their directions and also change their velocities. The time for which the two ...

Gas Laws ( Boyle’s Law, Charles Law & Combined Gas law)

Different states of gases ,Boyle’s Law, Charles Law & Combined Gas law

Gases There are three physical states of matter i.e., gases, liquids and solids. Behavior of gases is simpler and there is uniformity in the properties of gases. When the external conditions of temperature and pressure are changed, then the volume of the gases are affected to some extent. That is why all the gases more or less follow the same ...
