As shown in the figure at 200 K and 500 atm value of compressibility factor is 2(approx). Then the volume of the gas at this point will be:
The compressibility factor of a gas is less than 1 at STP. Its molar volume Vm will be
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 questions.
(i) How will the volume of a gas change if its presuure 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?
