A gram mole of a gas at $2 7^{\circ}$ C expands isothermally until its volume is doubled. Calculate the amount of work done. ( $R = 8$ J $m o l^{- 1}$ $K^{- 1}$ )

Answer:

1660

Solution:

$W = RT ln 2 = 8 \times 300 \times 0.693 = 1.66 \times 1 0^{3}$ J (with $R = 8.314$ it is $1.73 \times 1 0^{3}$ J).
