                  Consider P-V diagram for an ideal gas shown in Fig.                 Out of the following diagrams (Fig.), which represents the T-P diagram?                                 (a) (iv)                                   (b) (ii)                 (c) (iii)                                   (d) (i)                

Answer:

                  (c) Fig. 3 represents PV = constant (Boyle?s law)                 This implies that temperature (T) is constant. Further, from 1 to 2, pressure decreases. Thus T-P, diagram is represented by (iii).
