For V versus T plot at constant pressure P1 and P2 for an ideal gas is given in adjoining figure. Which of the following relation is correct ?

We know that ideal gas equation is given by- PV=nRT where, P=Pressure V=Volume n=no. of moles R= Universal gas constant T= Temperature Now, nR V T P So, we can see from the equation, nR P is the slope. When V increases, slope will also increase which implies that higher the slope, lower will be the pressure. Hence, from the figure we can say that 1 2 P P Thus, the correct option is (a).
