      Pressure versus volume graph for a real gas and an ideal gas are shown in fig. 5.4. Answer the following questions on the basis of this graph.   (i) Interpret the behaviour of real gas with respect to ideal gas at low pressure. (ii) Interpret the behaviour of real gas with respect to ideal gas at high pressure. States of Matter : Gases and Liquids (iii) Mark the pressure and volume by drawing a line at the point where real gas behaves as an ideal gas.

    Answer:

      (i) At low pressure, the curves of real and ideal gases arevery close, it means at low pressure, the real gases behave like ideal gas. (ii) The graph shows that, real gas is deviating largely from ideal behaviour at high pressure. (iii) See the dotted lines in the figure.
