The molecular weight of a gas is 44. The volume occupied by 
of this gas at 
and 
pressure will be
of this gas at and pressure will be
2.
The vapour of a substance behaves as a gas
3.
Two different masses 
and 
of an ideal gas are heated separately in a vessel of constant volume, the pressure 
and absolute temperature 
graphs for these two cases are shown in the figure as 
and 
The ratio of slopes of curves 
to is
and of an ideal gas are heated separately in a vessel of constant volume, the pressure and absolute temperature graphs for these two cases are shown in the figure as and The ratio of slopes of curves to is
4.
Pressure of an ideal gas is increased by keeping temperature constant. What is the effect on kinetic energy of molecules?
5.
A monoatomic gas molecule has

If the ratio of vapour density for hydrogen and oxygen is 
then under constant pressure the ratio of their 
velocities will be
then under constant pressure the ratio of their velocities will be
7.
An experiment is carried on a fixed amount of gas at different temperatures and at high pressure such that it deviates from the ideal gas behavior. The variation of 
with is shown in the diagram. The correct variation will correspond to
