The p-T graph for the given mass of an ideal gas is shown in figure. What inference can be drawn regarding the change in volume (whether it is constant, increasing or decreasing) ? How to proceed Definitely, it is not constant. Because when volume of the gas is constant `p-T` graph is a straight line passing through origin. The given line does not pass through origin, hence volume is not constant. . `V = (nR)((T)/P)` Now, to see volume of the gas we will have to see whether `(T)/(P)` is increasing or decreasing.

1.	The p-T graph for the given mass of an ideal gas is shown in figure. What inference can be drawn regarding the change in volume (whether it is constant, increasing or decreasing) ? How to proceed Definitely, it is not constant. Because when volume of the gas is constant `p-T` graph is a straight line passing through origin. The given line does not pass through origin, hence volume is not constant. . `V = (nR)((T)/P)` Now, to see volume of the gas we will have to see whether `(T)/(P)` is increasing or decreasing.
Answer» Correct Answer - A::B From the given graph, we can write the `p - T`equation as `p = aT + b` Now, `T _B gt T_A` :. `b/(T_B)lt b/(T_A) or (P/T)_B lt(P/T)_A` or `(T/P)_B gt(P/T)_A` or ` V_B gt V_A` Thus, as we move from `A` to `B`, volume of the gas is increasimg.
