Gas is Compressible Inflating Flotation Storage Propulsion
Natural Gas • It is drilled from gas fields (fossil fuel: mainly methane) • A smell is added to it • It is flammable • Hazardous to life as it is explosive
Helium • It is colourless, odourless and has no taste. • It is the second lightest gas after hydrogen. • Used to fill balloons and air ships.
Carbon Dioxide • Present in the earth’s atmosphere, it contributes to Global Warming. • Colourless gas. • Used to make fizzy drinks as it is soluble in liquids
Air • Part of the earth’s atmosphere. • Made up of other gases: Mainly Hydrogen and Oxygen • Air can vary in temperature and in density around the earth
