UV Spectroscopy: UV spectroscopy is concerned with ranges from 190 to 370 nm. Compound which are colourless absorb radiation in UV range. In both UV as well as visible spectroscopy only the valence electrons absorb the energy there by molecule undergoes transition from ground state to exited state. This absorbance is characteristic and depends on the nature of the electron present. The intensity of the electron depends on the concentration and path length as given by Lambert beer’s law. Lambert

INVESTIGATORY PROJECT ABSTRACT: Adding oil to candle wax would soften it. The wax would melt at a lower temperature and the candle would drip more and burn down faster. The flame would also be larger than a flame on a candle with hard wax. Also‚ the flame would produce more soot and there would probably be an odor from whatever was cooked in the oil before it was used in the candle. Results of the tests showed that the candle made from 100 percent paraffin wax had the lowest melting rate‚ lowest

What is the Difference between Flammable and Combustible Liquids? Put simply‚ flammable and combustible liquids are liquids that can burn. The real difference lies within their flash point range‚ or lowest temperature at which vapours of the material will ignite when supplied with an ignition source. Flammable and combustible liquids are utilised in most workplaces‚ from manufacturing to retail and service entities. To ensure the safety of property‚ people‚ and the environment‚ both flammable

1.1 INTRODUCTION Leather is a durable and flexible material created by the tanning of animal rawhide and skin often cattle hide. It can be produced through manufacturing processes ranging from cottage industry to heavy industry. Leather comes from tanneries in various shapes and sizes depending on its intended use and the animal which it came from one thing to always remember about leather- it is an animal’s skin that has been processed into finished leather‚ not a synthetic material.

Upton Sinclair wrote the novel The Jungle along with several other politically-charged novels. Primarily motivated by politics‚ Sinclair wrote novels encouraging socialism and condemning capitalism. The literary period‚ the historical events‚ his family background‚ his job experience‚ and his political opinion inspired Sinclair’s desire to write The Jungle. The bold novel incited bold reactions of both support and criticism. Despite the opinions of the critics‚ Sinclair’s political outcry is
