Q. One mole of an ideal gas expands at a constant temperature of $300\ K$ from an initial volume of $10\ litres$ to a final volume of $20\ litres$. The work done in expanding the gas is $(R = 8.31\ J/mole$-$K)$

A) $750\ joules$
B) $1728\ joules$
C) $1500\ joules$
D) $3456\ joules$
Explanation

(b) $W_{iso} = \mu RT\log_{e}\frac{V_{2}}{V_{1}} = 1 \times 8.31 \times 300\log_{e}{\frac{20}{10} = 1728J}$
