A physical property is any property that is measurable, whose value describes a state of a physical system. The changes in the physical properties of a system can be used to describe its changes between momentary states. Physical properties are often referred to as observables. They are not modal properties
A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.
Hydrogen also has many other uses. In the chemical industry it is used to make ammonia for agricultural fertilizer (the Haber process) and cyclohexane and methanol, which are intermediates in the production of plastics and pharmaceuticals. It is also used to remove sulfur from fuels during the oil-refining process.
meaning of cyclohexane--a colorless flammable liquid cycloalkane obtained from petroleum or by hydrogenating benzene, and used as a solvent and paint remover.
