Kinetic Theory ...

Assertion: PV/T=constant for 1 gram of gas. This constant varies from gas to gas.

Reason:1 gram of different gases at NTP occupy different volumes. 

To find out degree of freedom, the correct expression is :

A vessel contains air and saturated vapor. The pressure of air is $$\mathrm{p}_{2}$$ and $$\mathrm{p}_{1}$$ is the S.V. P. On compressing the mixture to one-fourth of its original volume, what is the increase in pressure of the mixture?

The amount of heat energy required to raise the temperature of $$1\ g$$ of Helium at NTP, from $$T_1K$$ to $$T_2K$$ is -

At change of state the kinetic energy of the molecules of a substances increases greatly.

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 $$\dfrac{v}{3}$$ and the temperature to $$\dfrac{T}{3}.$$ The pressure of the gas will now be :
