What would have been the effect on gas pressure, if the collision between gas molecules were not classic?
How will you account for the fact that gases occupy the whole of the volume available to them?
Due to the absence of attractive forces between molecules, the molecules of gases can easily separate from one another.
The tyre of an automobile is inflated to a slightly lesser pressure in summer than in winter. Why?
The size of the weather ballon becomes larger and larger as it ascends to higher altitudes. Explain.
What change is expected if the temperature is kept constant but pressure is reduced to one fourth of its original value?
