A lifting gas or lighter than air gas is a gas that has a lower density than normal atmospheric gases and rises above them as a result. It is required for aerostats to create buoyancy, particularly in lighter-than-air aircraft, which include free balloons, moored balloons, and airships.Only certain lighter than air gases are suitable as lifting gases. Dry air has a density of about 1.29 g/L ...

Liquefied natural gas (LNG) is natural gas (predominantly methane, CH 4, with some mixture of ethane, C 2 H 6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport.It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure).. LNG is odorless, colorless, non-toxic and …
