Ideal-Gas Law

Description
The ideal gas laws are explained along with the fact that mass does not enter in the gas equation.Gases which follow the gas laws closely is Oxygen, many such examples are given.Different forms of gas equation in terms of Boltzmann's constant etc are derived. A Copper vessel with a pressure gauge is put in ice and then in boiling water. The reading of the pressure gauge agrees wonderfully with the calculation using gas laws. Th other concept introduced is that of Phase diagram. The state of Carbon-di Oxide gas in an extinguisher is found using Phase diagram.Effect of pressure on boiling point is explained on the basis of phase diagram.The class ends with two interesting questions on Helium balloon and a can of tennis ball.
