Three moles of an ideal gas at 300 K are isothermally expended to five times its volume and heated at this constant volume so that the pressure is raised to its initial value before expansion. In the whole process 83.14 kJ heat is required. Calculate the ratio \[{{C}_{P}}/{{C}_{V}}\]of gas \[\left( {{\log }_{e}}5=1.61 \right)\]

Answer:

1.42
