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:
“I was curious, I was avid to know only what I found more real than myself, that which allowed me to glimpse the thoughts of a great genius, or the force or grace of nature left to its own devices, without the intervention of man.”
—Marcel Proust (1871–1922)
“Shielded, what sorts of life are stirring yet:
Legs lagged like drains, slippers soft as fungus,
The gas and grate, the old cold sour grey bed.”
—Philip Larkin (1922–1986)
“All social rules and all relations between individuals are eroded by a cash economy, avarice drags Pluto himself out of the bowels of the earth.”
—Karl Marx (1818–1883)
