Question

Which of the following graphs represent the behavior of an ideal gas ? Symbols have their usual meaning.

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

Using ideal gas equation,

$PV=nRT\Rightarrow \left(PV\right)=nR\left(T\right)$

$PV\propto T(nR=\text{constant})$

So, the graph will be a straight line with positive slope $\left(nR\right)$ and passing through origin.

Thus, option $\left(\text{C}\right)$ is the correct choice.
