1.	Draw the P-T and V-T diagrams for an isobaric process of expansion, corresponding to n moles of an ideal gas at a pressure P_(0), from V_(0) to 2V_(0).
Answer» Solution :For the graph PF P versus T the variation is a straight line NORMAL to the pressure axis, the temperature varying from `T_(1) " to " T_(2)` as shown FIGURE. From the gas EQUATION `PV=nRT` we have, `V=[(nR)/P_(0)]T or V prop T` At `V=V_(0),T_(1)=(P_(0)V_(0))/(nR)` and at `V=2V_(0), T_(2)=(2P_(0)V_(0))/(nR)` From the graph of V versus T, the equation `V=[(nR)/P_(0)]T` or V=KT shows that the volume varies directly, as the temperature (Charless. law). So, the graph is a straight line inclined to the `(V-T)` axis, and passing through the origin (whenproduced) as shown in figure.
