When a certain gas under a pressure of 5.00 x 10^6 Pa at 25.08 oC is allowed to expand to 3.00 times its original volume, its final pressure is 1.07 x 10^6 Pa. What is its final temperature?

State the assumptions that are made in the kinetic theory of gases and derive an expression for the pressure exerted by a gas which conforms to these assumptions, in terms of density and the root mean square velocity of its molecles

Assuming the density of nitrogen at s.t.p to be 1.251 kgm^-3, find the root mean square velocity of nitrogen molecules at 127 oC.

Use the concepts of the elementary kinetic theory of gases to derive an expression for the root mean square velocity of the molecules of a gas(Nitrogen) in terms of the pressure and density of the nitrogen gas.

Explain what is mearnt by the root mean square velocity of the molecules of a gas.
