At pressure P and absolute temperature T a mass M of an ideal gas fills a closed container of volume V. An additional mass 2M of the same gas is added into the container and the volume is then reduced to `V/3` and the temperature to `T/3`. The pressure of the gas will now be:

A closed vessel of fixed volume contains a mass m of an ideal gas, the root mean square speed being v. Additional mass m of the same gas is pumped into the vessel and the pressure rises to 2P, the temperature remaining the same as before. The root mean square speed of the molecules now is :

An ideal gas with pressure P , volume V and temperature T is expanded isothermally to a volume 2V and a final pressure P_i . If the same gas is expanded adiabatically to a volume 2V , the final pressure is P_a . The ratio of the specific heats of the gas is 1.67 . The ratio of P_a / P_i is ........
