Question

Consider a graph plotted between $p$ and $\frac{1}{V}$ as shown below :

The correct order of temperature $T_{1}, T_{2}, T_{3}$ will be

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

Answer 1

Answer: (A)

$p V=$ constant at constant temperature. Higher curves corresponds to higher temperature. Hence, the correct order is
$T_{3} >T_{2} >T_{1}$
