Someone please explain me to me what are the parameters which determine whether a particular curve will pass through the origin or not.First please explain for the P-V Graphs & then for all cases ie make it general.In the fig. that I have attached,ab is passing through the origin.Please explain the reason & similarly for V-T &P-T Graphs too.
Click on the figure & open with any software to see the whole fig.
