Top 10 facts about the world. Compressive strength is a measure of a materialâs ability to withstand compressive forces, where it is squeezed laterally.Materials testing can determine the compressive strength of a material in optimal conditions, using a specialized device that applies known pressure loads to materials of interest.op 10 facts about the world.

VX gas is one of the most dangerous chemicals created by man. VX gas is an aerosoled chemical warfare agent derived from the oil-based VX. In the film The Rock, it was that green liquid that the terrorists threatened San Francisco Bay with.
The essential component for any breathing gas is a partial pressure of oxygen of between roughly 0.16 and 1.60 bar at the ambient pressure.The oxygen is usually the only metabolically active component unless the gas is an anaesthetic mixture. Hydreliox is a mixture of oxygen, helium, and hydrogen and is used for dives below 130 metres in commercial diving. 2  Hydrox, a gas mixture of hydrogen and oxygen, is used as a breathing gas in very deep diving. 3  Neox (also called neonox) is a mixture of oxygen and neon sometimes employed in deep commercial diving.
