One mole of an ideal gas expands isothermally and reversibly from $\displaystyle 10 \mathrm{dm}^3$ to $\displaystyle 20 \mathrm{dm}^3$ at $\displaystyle 300$ K . $\displaystyle \Delta \mathrm{U}, \mathrm{q}$ and work done in the process respectively areGiven: $\displaystyle \mathrm{R}=8.3 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}$ $\displaystyle \ln 10=2.3$ $\displaystyle \log 2=0.30$ $\displaystyle \log 3=0.48$
