text: If the temperature is low enough the gas can condense and turn into a liquid.
text: Sometimes, if the temperature is low enough it can go through deposition, where it changes straight to a solid.
text: Normally a gas must first condense to a liquid, and then freeze to become a solid, but if the temperature is very low it can skip the liquid stage and instantly become solid.
text: Some other gases exhibit this phase change if the ambient temperature is low enough; this includes ethylene (R1150), carbon dioxide (R744), ethane (R170), nitrous oxide (R744A), and sulfur hexafluoride; however, these can only be liquefied under pressure if kept below their critical temperatures which are 9 °C for C 2 H 4 ; 31 °C for CO 2 ; 32 °C for C 2 H 6 ; 36 °C for N 2 O ; 45 °C for SF 6 .
text: Because work is extracted from the expanding high-pressure gas, the expansion is approximated by an isentropic process (i.e., a constant-entropy process), and the low-pressure exhaust gas from the turbine is at a very low temperature,
