WebSep 12, 2024 · When an ideal gas is compressed adiabatically \((Q = 0)\), work is done on it and its temperature increases; in an adiabatic expansion, the gas does work and its temperature drops. Adiabatic compressions actually occur in the cylinders of a car, where … WebBottom line: whether the compression makes more liquid or more gas depends not just on p and T but also on the starting liquid/gas ratio. There's a special liquid/gas ratio at each T, and whichever phase beats that ratio gains further, compared to the special ratio, as the cylinder is compressed. It's sort of like economics. dal tile warehouse
