Which is more stable out of gas and Vapour?
A vapor is a substance diffused or suspended in the air, like smoke or fog, while a gas is homogeneous. A vapor can be liquefied by pressure alone, while a gas can not. Under either definition the gas is a more stable state as there are fewer events that can upset them.
Is natural gas a vapor or liquid?
Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport.
