The variation of pressure with volume of...

The variation of pressure with volume of the gas at different temperatures can be graphically represented as shown in figure. On the basis of this graph answer the following question.
(i) How will the volume of a gas change if its pressure is increased at constant temperature ?
(ii) At a constant pressure, how will the volume of a gas change if the temperature is increased from 200 K to 400 K ?

Text Solution

Verified by Experts

(i) The volume of a gas will decrease if the pressure on the gas is increased keeping the temperature constant.
(ii) On increasing temperature, the volume of a gas will increase if the pressure is kept constant.
