Question

The ideal gas equation for 1 mol of ideal gas is PV = nRT

The graph between P and T at constant volume, i.e. isochores are plotted as under



Which of the following order of volume is correct?

• A. $V_{4}>V_{3}>V_{2}>V_{1}$
• B. $V_{1}>V_{2}>V_{3}>V_{4}$
• C. $V_{1}=V_{2}=V_{3}=V_{4}$
• D. $V_{2}>V_{1}>V_{3}>V_{4}$

Answer 1

Answer: (B)

At constant temperature T, $V \propto \frac{1}{P}$ (for 1 mol gas).

Thus, correct sequence of volume will be

$V_{1}>V_{2}>V_{3}>V_{4}$
