Like the millipedes, centipedes are highly segmented (15 to 177 segments), but with only one pair of walking legs per segment (millipedes have two legs per segment). The head of a centipede has a pair of antennae, jaw-like mandibles (called forcipules) and other mouthparts.
Although compressed natural gas (CNG) is a fossil fuel like diesel, gas and coal, it is far different in terms of its impact on the natural environment.
LPG is an acronym for Liquefied Petroleum Gas. LPG is gas that can be compressed into a liquid. Wet gas is a term that is sometimes used to describe LPG, as a result of this property. It may also be referred to as Natural Gas Liquids -- NGL.ollowing its refinement, LPG is stored as a liquid under pressure until used, at which point it becomes a gas or vapour. In Australia, LPG is Propane. Propane is a three carbon molecule with the formula C3H8.
