Heat Capacity Ratio - Real Gas Relations

Real Gas Relations

As temperature increases, higher energy rotational and vibrational states become accessible to molecular gases, thus increasing the number of degrees of freedom and lowering . For a real gas, both and increase with increasing temperature, while continuing to differ from each other by a fixed constant (as above, = ) which reflects the relatively constant P*V difference in work done during expansion, for constant pressure vs. constant volume conditions. Thus, the ratio of the two values, decreases with increasing temperature. For more information on mechanisms for storing heat in gases, see the gas section of specific heat capacity.

Famous quotes containing the words real, gas and/or relations:

    Everyone likes the obscene; that is real life.
    Christina Stead (1902–1983)

    ... when I awake in the middle of the night, since I knew not where I was, I did not even know at first who I was; I only had in the first simplicity the feeling of existing as it must quiver in an animal.... I spent one second above the centuries of civilization, and the confused glimpse of the gas lamps, then of the shirts with turned-down collars, recomposed, little by little, the original lines of my self.
    Marcel Proust (1871–1922)

    In the relations of a weak Government and a rebellious people there comes a time when every act of the authorities exasperates the masses, and every refusal to act excites their contempt.
    John Reed (1887–1920)
