Draws the P-Tand 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` From the equation state PV = nRT

Explanation

we have` V = ((nR )/(P_n))T or V prop T `
`At V=V_0 =T_1 =(P_0 V_0)/( nR ) and at V=2V_0 , T_1 = ( 2P_0 V_0 )/(nR )`
For the graph of 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 graph of V versus T, the equation `V=((nR)/(p_0) )T `
(or) V = KT shows that the volume varies directly, as the temperature (Charles. law). So, the graph is a straight line inclined to the (V T) axis, and passingthrough the origin (when produced) as shown in figure.
