At a given temperature, equal masses of monoatomic and diatomic gases are supplied equal quantities of heat. Which of the two gases will suffer a larger temperature rise?

Answer:

                The temperature of the monoatomic gas will rise by a large value. In case of the monoatomic gas, the heat supplied is used entirely to increase the translational K.E. of the molecules. In case of the diatomic gas, the heat supplied is used to increase the translational, rotational and sometimes even the vibrational kinetic energy of themolecules. It is only the translational K.E. which increases the temperature.
