CBSE Class 11-science Answered

The volume of a gas sample is increased.  Why does the pressure, which is exerted by the gas, decrease?

answered-by-expert Expert Answer

As the volume of a gas is increased, its pressure decreases because of the fact that :

(i)  The molecules have to travel a longer distance between impact on the walls of the container.

(ii)  These impacts are now distributed over a larger area.
