Energy required to increase the temperature of one mole of monoatomic gas by $\Delta T =3 / 2 \times R \times \Delta T$
Energy required to increase the temperature of one mole of a diatomic gas by $\Delta T =5 / 2 \times R \times \Delta T$
So, for equal volume i.e. equal moles equal amount of heat will increase the temperature of a monoatomic gas more than the diatomic gas
