Question

Explain how gases can be liquified?

Answer 1

Cooling and High Pressure!i

Answer 2

1 Cooling - for example, hot water vapour in the air after a shower hitting a cold glass surface like a mirror in the bathroom

2 Increase pressure

3 A combination of the above

Answer 3

It is pressurized to about 3000 psi. and cooled down ,it will condense except methane. Methane does not like to compres,it is like trying to compres water.

Answer 4

It is basically a two step process.

First you do work on the gas by compressing it.  This will reduce the volume, but heat the gas.

Second, you cool the heated gas below the temperature at which the gas will condense at the high pressure that is left after the cooling.

Third, the temperature can be slowly raised to distill off specific gases if necessary.

Answer 5

By high compression.

either by cooling or by increasing pressure....
