Consider the 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)
In the graph given in question,
PV=constant
And PV=nRT
So, T=constant
And, on going from 1 to 2 'P' decreases. These two conditions are satisfied by the graph in option (iii)
Hence, the correct option is C (iii)
