Question

One mole of an ideal gas expands isothermally and reversibly from $10 \, \mathrm{dm}^{3}$ to $20 \, \mathrm{dm}^{3}$ at $300 \, \mathrm{K}$ . $\Delta U$ , $q$ and work done in the process respectively are :

Given : $\mathrm{R}=8.3 \, \mathrm{J K}^{-1} \, \mathrm{mol}^{-1}$

In $10=2.3$ $\log 2=0.30$ $\log 3=0.48$
