Try a question.
Heat is supplied to a diatomic gas at constant pressure. Then the ratio of ΔQ : ΔU : ΔW is ________.
At constant pressure ΔQ : ΔU : ΔW = Cp : Cv : R. For a diatomic gas Cv = 5R/2 and Cp = 7R/2, so the ratio is 7 : 5 : 2.
Common mistakeUsing monatomic values (Cv = 3R/2), which gives 5 : 3 : 2.
