Question

Which one of the following graph represents the behaviour of a ideal gas? Assume pressure is constant.

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

According to Charle's law,
For constant pressure,
$V\propto T\Rightarrow \frac{V}{T}=\text{constant (K)}$
Let $V=x$ and $\frac{1}{T}=y$
$\therefore xy=K\Rightarrow y=\frac{K}{x}$
