When a sample of ideal gas is changed from an initial state to a final state, various curves can be plotted for the process like P-V curve, V-T curve,P-T curve etc. For example, P-V curve for a fixed amount of an ideal gas at constant temperature is a rectangular hyperbola, V-T curve for a fixed amount of an ideal gas at constant volume is again a straight line. However, the shapes may vary if the constant parameters are also changed. Now, answer the following questions : From the given plot between Z and P for a real gas the correct is :

Answer» `T_1=(2A)/(Rb)` `T_2=(a)/(Rb)` `T_3=(a)/(Rb)` `T_4=(2a)/(Rb)` Solution :Graph corresponding to `T_2` shows IDEAL BEHAVIOUR for a range of PRESSURE. Hence, `T_2=a/(Rb)`
