At a `g_(n)` temperature equal masses of monoatomic & diatomic gases are supplied equal quantities of heat. Which of the two gases will suffer a larger temperature rise?

Explanation

(i) The temperature of monoatomic gas will rise by a large value.
(ii) In caes of the monoatomic gas, the heat supplied is used entirely to increase the translational K.E of the molecules.
(iii) In case of the diatomic gas. The heat supplies is used to increase the translational, rotational and some times even the vibrational K.E of the molecules.
(iv) It is only the translational K.E which increases the temperature.
