Text Solution

AI Generated Solution

To determine the shape of the curve obtained by plotting pressure (P) against the product of pressure and volume (PV) at constant temperature for an ideal gas, we can follow these steps: ### Step 1: Understand the Ideal Gas Law The ideal gas law is given by the equation: \[ PV = nRT \] Where: - \( P \) = Pressure of the gas - \( V \) = Volume of the gas ...

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 :
