- ISL 9y agoTake it to high-enough pressure while keeping it at room temperature, and it will liquify.
- philipkglass 9y agoPressure alone is sufficient only when the substance is below its critical temperature. The critical temperature for methane is 190.6 K, some 107 degrees below room temperature. Gases that are highly compressed above their critical point form a supercritical fluid, which can have liquid-like density but does not have a defined volume. LNG is a true liquid, stored at cryogenic temperatures and low pressure.
- simbas 9y agoNo. It is not practical to liquify by compression. See: https://www.youtube.com/watch?v=QgtSoEJD9HE https://www.youtube.com/watch?v=QgtSoEJD9HE It seems it's hard to liquify by pressurisation.
- tim333 9y agoThe basics of it is squash a gas and it gets hot. Let cool then expand and it gets colder. Keep going till -160C and you have liquid gas.
