ANTECEDENT.Elementary concept of Chemistry Civil Engineering

Chemistry learn about material structure and natural by changes this items in course of natural and also in planned experiment.

Descriptive chemistry marking differentiating one from another, elaborating the condition of that essence interaction, and summarize the nature of and new usefulness any kind of which is yielded.

Chemistry of Teoristis explain why that change happened. Material science discipline science with aim to specify relation

between structure, nature of and prosessing of solid material. this Application science under knowledge of physics and chemistry.

5 CLASS MATERIAL1. Metals : any kind of or chemical elements combination like

gold, silver, iron, aluminium. Metal represent conductor which good to electrics and heat.

2. Ceramic : Greek of keramos (earth burnt), by tardisional ceramic is burned clay. Modern Ceramic may in the form of oxides, karbida-karbida, and borida-borida.

3. Polymer : Many Greek poly ; meros (part), materials of organic consist of to enchain from simple molecules which repeated.

4. Semiconductor : Material like Si and Ge with nature of electrics between ceramic and metal.

5. Composite : made Material from all kinds of shares; physics mixture from two or more materials.

NATURE OF ITEMS

Every essence have the nature of, for example salt and sugar have the nature of white chromatic, solid, dissolve crystal in water, but sweet sugar likely. Sugar burnt on the air and new salt melt after heat etc.Nature of intrisink is the quality of having the character of typically every example of size measure and form.Nature of ekstrisink is the nature of which do not typically from itself Iihat vitamin. Size measure, long form, weight, and temperature.Nature of chemistry is the nature of intrisink, for example ethyl of alcohol flammable, rusty iron etc. Earn also referred is typical quality causing that essence exchange, goodness alone and also have interaction with other essenceNature of Physics is characteristic, differentiating from other essence and not entangle any change to other essence.

Change in Items and of Energi.• Change of chemistry result to lose essence and

forming of new essence.• Change of Physics is changes which do not

cause the happening of forming of new essence. • Change of Energy is ability of system or object

work, every change of chemistry and or physics, entangling change of energy Various form of energy.
