Q.

Consider the reversible isothermal expansion of an ideal gas in a closed system at two different temperatures T1 and T2 (T1 < T2). The correct graphical depiction of the dependence of work done (w) on the final volume (V) is:

  1. A

  2. B

  3. C

  4. D

Solution

Work done in an isothermal reversible expansion is given by 

W = -2.303 nRT log

|W| = nRT ln

|W| T for the same values of V1 and V2

|W| = +ve if V2 = 1 L and V1 is fraction of a litre
