A liquid substance, like water or gasoline, normally is a liquid at ambient temperature and pressures.
A liquified gas, like LPG or liquified natural gas, exists as a liquid as the result of compression and
cooling to temperatures and pressures unlike the ambient temperatures and pressures.
gas
When a gas is changed to a liquid the gas has condensed, or liquefied or cooled.
That the gas has liquefied.
NGL is not liquefied natural gas, which is condensed natural gas that is compact and therefore convenient for overseas shipping.
Liquefied petroleum gas is a gas at room temperature but is compressed into a liquid for transportation.
liquefied petroleum gas and liquid propone gas LPG stands for "Liquified Petroleum Gas" or "Liquid Propane Gas". The term is commonly used when describing the gas tanks of vehicles which run on such fuel.
Natural gas (out of the ground) that has been compressed until it forms a liquid.
LP gas is liquid in the tank. It is the evaporation of that liquid that produces the gas. LP=Liquid Propane, or Liquefied Petroleum
LPG stands for Liquefied Petroleum Gas, which means that it is a gas which has been compressed to liquid in cylinders. For more info, go this website: http://en.wikipedia.org/wiki/Liquefied_petroleum_gas
Ice is a solid, water is a liquid, and oxygen is a gas in the air we breath.
LPG, which stands for liquefied petroleum gas, is a mixture of propane and butane gases that exist in a liquid state when compressed.
Steam and vapor are in the form of a gas. Liquid water is in the form of a liquid.
