Identify the correct variation of pressure and volume of a real gas (A) and an ideal gas (B) at constant temperature. (y=p ; x=V)

Step-by-step solution

Ideal gas equation =p V=n R T On rearranging p= n R T V or V= n R T p i.e. p 1 V or V 1 p is correct plot. At low pressures, the real gas shows very small deviation from ideal behaviour and the curve for ideal gas and real gas almost coincides. There is a large deviation from ideal gas behaviour at high pressure, hence the curve are far apart.
