Match the following graphs of ideal gas with their co-ordinates:

(i) – (b)

(ii) – (c)

(iii) – (a)

Plot (i) shows the plot of p vs V, which is nothing but the Boyle’s law plot,

As according to the Boyle’s law:

p1V1 = p2V2 = constant

if we plot the p vs V graph, we observe that the V increase exponentially with the decrease in the pressure.

Plot (ii) again shows the plot of p vs , which is representing the Boyle’s law plot,

As according to the Boyle’s law:

p vs.

Which means if p increases, also increases, and vice versa.

Hence, straight line passing through origin is formed.
