Select correct statement(s).

A

we can condense vapours simply by applying pressure

B

To liquefy a gas one must lower the temperature below `T_(C)` and also apply pressure

C

At `T_(C)`, there is no distinction betwwen liquid and vapour state, hence density of the liquid is nearly equal to density of the vapour

D

All the statements are correct.
