\({(\Delta Q)_P} = \mu \,{C_P}\Delta T\)

\(\Rightarrow\)  \(207 = 1 \times {C_P} \times 10\)

\(\Rightarrow\) \({C_P} = 20.7\,\frac{{Joule}}{{mol{{ - }}K}}\)

\({C_P} - {C_V} = R\)

\(\Rightarrow\) \({C_V} = {C_P} - R\)\( = 20.7 - 8.3 = 12.4\,\frac{{Joule}}{{mole{\rm{ - }}K}}\)

\({(\Delta Q)_V} = \mu \,{C_V}\Delta T = 1 \times 12.4 \times 10 = 124\,J\)
