Equal masses of monoatomic and diatomic gases are supplied heat at the same temperature, pressure and volume. If same amount of heat is supplied to both the gases, which of them will undergo greater temperature rise?
For monoatomic gas, temperature rise will be greater because monoatomic gas possesses only transladonal degree of freedom whereas diatomic gas translation, rdtation and vibrational (at higher temperature), so temperature size for diatomic gases is lower.
