Answer

The internal energy for diatomic molecule is the sum of translational kinetic energy, rotational kinetic energy and vibrational energy. So, a monatomic and diatomic gas with same temperature will have same average kinetic energy but diatomic gas will also have rotational and vibrational energy which will contribute to its internal energy.
