Neoprene is superior to natural rubber because of the following properties: Neoprene is non-inflammable but natural rubber is inflammable Neoprene is resistant to oils, organic solvents, petrol and grease. Natural rubber swells and rots in contact with these materials Neoprene is stable ev..

Static electricity was known to people more than 2500 years ago. The Greeks knew about the attractive property of the resin amber. They knew that by rubbing amber with cloth, it could be made to attract small feathers. The Greek name for amber was 'elektron'. After about a thousand years ..

Polymerization - is the process of formation of large molecules or macromolecules with high molecular weight from small molecules. 'Poly' means many and 'meros' means parts in Greek. The simple compounds from which these macromolecules are made are called monomers . When two monomers combine, a dim..

Excretion in Plants - In plants, breakdown of substances is much slower than in animals. Hence accumulation of waste is much slower and there are no special organs of excretion. Green plants in darkness or plants that do not contain chlorophyll produce carbon dioxide and water as respiratory waste ..
