Both Graphite and Diamonds are pure forms of Carbon! Yes! The chemical composition of the two are exactly the same. Can you believe it? This makes graphite and diamond allotropes of carbon. That is, graphite can be converted to diamond under high pressure (>100 k bar) and temperature (>2000oC). Allotropy is the existence of an […]

Fluorescence is the ability of certain chemicals to release visible light after absorbing an invisible radiation, such as ultraviolet light. It is a form of luminescence where molecules on absorbing light energy excites to a higher energy state, also known an excited state. Since the energy of the excited state is too high the molecule cannot sustain […]
The quantitative property transferred to a body or a physical system, recognizable in the performance of work is known as energy. It can be in the form of heat and light. Energy is a conserved quantity that is it can neither be converted nor destroyed. It can only be converted from one form to another and this is known as the law of conservation of energy. The […]
