One mole of an ideal gas expands isothermally and reversibly from $10{\rm{d}}{{\rm{m}}^3}$ to $20{\rm{d}}{{\rm{m}}^3}$ at 300 K. $\Delta {\rm{U}},{\rm{q}}$ and work done in the process respectively are
Given: ${\rm{R}} = 8.3\;{\rm{J}}\;{{\rm{K}}^{ - 1}}\;{\rm{mo}}{{\rm{l}}^{ - 1}}$
$\ln 10 = 2.3$
$\log 2 = 0.30$
$\log 3 = 0.48$
