Thermodynamics -- mono and diatomic gases

[Any Help]

Homework Statement

The 4 processes involve one mole of either mono- or di-atomic gas with the same amount of heat (absorbed or discharged)

•Which belong to the mono and which to the diatomic gas?

Homework Equations

i don't know which equations I should use and how start solving it..
I started thinking by taking into consideration the degrees of freedom of each but it didn't work

What is the molar heat capacity at constant volume for a monoatomic gas? What is the molar heat capactiy at constant volume for a diatomic gas?

What is the molar heat capacity at constant volume for a monoatomic gas? What is the molar heat capactiy at constant volume for a diatomic gas?

(molar heat capacity at constant volume=f/2 R where f is then number of degrees of freedom) I think it should be 3/2R for monoatomic and 7/2Rfor diatomic and delta T is inversly proportional to heat capacity. Similarly for heat capacity at constant pressure (Cp=R+Cv) so diatomic will get a lower temprature than monoatomic ones so 1,3 monoatomic and 2,4 diatomic
Correct?
