So much in fact, that it's compressed, but not to the point of liquefaction, when used as a fuel Exposed to the open air, these fuels are gaseous and highly inflammable. If you've cooked with gas, you'll know what that means. Lighting the burner after the pilot light's been extinguished can produce a mini-explosion.
