If one mole of a monatomic gas (γ=53) is mixed with one mole of a diatomic gas (γ=75) the value of γ for the mixture is:
One mole of ideal monoatomic gas (γ=53) is mixed with one mole of diatomic gas (γ=75). What is γ for the mixture? γ denotes the ratio of specific heat at constant pressure, to that at constant volume.
