Question

Consider $P-V$ diagram for an ideal gas shown in Figure.
Out of the following diagrams (Figure), which represents the $T-P$ diagram?

• A. (iv)
• B. (ii)
• C. (iii)
• D. (i)

Answer 1

The correct option is C (iii)

In the graph given in question,

$PV=constant$

And $PV=nRT$

So, $T=constant$

And, on going from $1$ to $2$ 'P' is decreasing. These two conditions are satisfied by the graph in option $\left(iii\right)$
