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 MATERIAL
1. 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 essence
Nature 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.
