Question

The given curve represents the variations of temperature as a function of volume for one mole of an ideal gas. Which of the following curves best represents the variation of pressure as a function of volume?

Moderate

A
B
C
D

Solution

Slope of line is 1. Therefore, T- V equation can be written as T = V + T₀
$∴$ $\frac{p V}{n R} = V + T_{0} \Rightarrow p = (n R) + \frac{n R T_{0}}{V}$
$∴$ p versus V graph is a sort of rectangular hyperbola.
