Perfect Gas Nomenclature
The terms perfect gas and ideal gas are sometimes used interchangeably, depending on the particular field of physics and engineering. Sometimes, other distinctions are made, such as between thermally perfect gas and calorically perfect gas, or between imperfect, semi-perfect, perfect, and ideal gases. The assumptions are summarized in the following table.

Famous quotes containing the words perfect and/or gas:
“With sudden roar and aged pine-tree falls,—
One crash, the death-hymn of the perfect tree,
Declares the close of its green century.”

“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.”
