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. 

1. Interpret the behaviour of real gas with respect to ideal gas at low pressure. 

2. Interpret the behaviour of real gas with respect to ideal gas at high pressure. 

3. Mark the pressure and volume by drawing a line at the point where real gas behaves as an ideal gas. 

This is a short answer type question as classified in NCERT Exemplar

1. At low pressure, the curve of real gas coincides  with that of ideal gas, this shows that the deviation of  behaviour of real gas with respect to ideal gas is small or negligible.

2. At high pressure, the curve of real gas is far apart from  ideal gas, this shows that the deviation of  behaviour of real gas with respect to ideal gas is large.

3. The  pressure p₁ and volume V₁  are  the point where real gas behaves as an ideal gas.
