Knowledge of basic ideas of Chemistry for Engineering students can facilitate them as skilled engineers later in style and material choice, moreover as utilizing the obtainable resources. Learning Objectives:
• Plastics square measure these days employed in menage appliances; conjointly they’re used as composites (FRP) in part and automotive industries.
• Fuels as a supply of energy square measure a basic want of any business, notably industries like thermal power stations, industry, plant food business etc., and thence they’re introduced.
• the fundamentals for the development of galvanic cells square measure introduced. conjointly if corrosion is to be controlled, one needs to perceive the mechanism of corrosion that itself is explained by chemistry theory.
• With the rise in demand, a good kind of materials square measure coming back up; a number of them have glorious engineering properties and a couple of of those materials square measure introduced.
• Water may be a basic material in the majority the industries, additional thus wherever steam is generated and conjointly wherever it’s provided for drinking functions.
• Materials employed in major industries like industry, metallurgic industries and construction industries and electrical instrumentality producing industries square measure introduced. conjointly lubrication is introduced.

the benefits and limitations of plastic materials and their use in style would be understood. Fuels that square measure used unremarkably and their economic science, blessings and limitations square measure mentioned. Reasons for corrosion and a few ways of corrosion management would be understood. the scholars would be currently tuned in to materials like nano materials and fullerenes and their uses. equally liquid crystals and superconductors square measure understood. The importance of inexperienced synthesis is well understood and the way they’re totally different from standard ways is additionally explained. The impurities gift in raw water, issues related to them and the way to avoid them square measure understood. the benefits and limitations
of plastic materials and their use in style would be understood. The unremarkably used industrial materials square measure introduced.
