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:
“Do you think that the things people make fools of themselves about are any less real and true than the things they behave sensibly about?”
—George Bernard Shaw (18561950)
“Papa died in the gas chamber,
slipping blue as an undressed minnow,
gulping in the shower to wash the Jew off him.”
—Anne Sexton (19281974)
“When any one of our relations was found to be a person of a very bad character, a troublesome guest, or one we desired to get rid of, upon his leaving my house I ever took care to lend him a riding-coat, or a pair of boots, or sometimes a horse of small value, and I always had the satisfaction of finding he never came back to return them.”
—Oliver Goldsmith (17281774)
