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.
