Comparison between heat in isothermal and isobaric

gaganpreetsingh

The initial pressure (P) and Volume(V) are same. Two processes one isothermal and other isobaric are carried out both ending at the same volume. In which case is more energy given to the gas as heat?

Q(isothermal) = nRT ln(Vf/Vi) Vf = final volume, Vi = initial volume
Q(isobaric) = n Cp (T2-T1) Cp= Molar specific heat at constant P.
How do I compare these expressions?
