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 :

Options

A. `T_1=(2a)/(Rb)`
B. `T_2=(a)/(Rb)`
C. `T_3=(a)/(Rb)`
D. `T_4=(2a)/(Rb)`

Answer

B

Explanation

Graph corresponding to `T_2` shows ideal behaviour for a range of pressure. Hence, `T_2=a/(Rb)`
