  A gas is liquified by cooling and pressure.  When the pressure is released
 the gas (now liquid) transforms back into a gas and in so doing absorbs
 heat from its surroundings.  Thus the surroundings lose heat get colder.

 not quite) to absolute zero.  A lot of details are left out but that's the

Nowadays they are using super powerful lasers to zap heat away from atoms..
