A Comprehensive Guide to Home Security Systems:

 Science: 

That idea which understanding this world and how it work is called Science.

Chemistry:

Chemistry is the branch of science which deal with study of an atoms,Molecule and their transformations this idea is called chemistry in simple way the study of matter is called chemistry.

Matter:

 Anything which has mass and occupies space is called matter. 

Matter has three types:

• Solid
• Liquid
• Gas

Solid: 

The solid has definite volume and definite shapes is called solid.

Example: chair,table,computer,rubber,disk,rubber,pencil,mouse,bulb,stone,

fan,machine,wire,door,shampoo bottle,loud speaker,hen,road,car,bike,ball,bat,cloth,board,etc.

Liquid:

The liquid has definite volume but not definite shape this idea is called liquid.

Example:

Water,oil,tea,coffee,etc.

Gas:

The gas neither definite volume nor definite shape this idea is called Gas.

Example:

Methane gas,boiling gas etc.

Importance of chemistry:

Petrochemistry: in this we we study about petrol by which chemistry is discovered very important rule by chemistry.

Medicines Drugs: 

By chemistry the medicines makled for human diseases as well is drug also.

Soap:

By chemistry the soap is made which is done to easy life for our life nowadays all places and much uses this kind of process.

Plastic:

 Nowadays you see plastic by chemistry is marked which talking all world benefits to easy their life.

Insecticides: 

Mainly you see nowadays Insecticides which are dangerous for whole sicity for finished used alot of sources marked by chemistry which are helpful to secure our life from Insecticides.

Health Environment:

Chemistry very important role in our life for environmental health.You can see in our society.

Disadvantages of chemistry:

Pollution: 

All of pollution is created by industry big disadvantages of chemistry.

Toxic Waste: 

The poisonous is being created by radioactive( which causing Cancer).

• bioaccumulative.> ( Increasing in chain of foods in form pof increasing.).
• mutagenic >(Which is to causing damage to chromosomes).
• teratogenic> (which is to be causing birth defects).

Contaminated water:

By chemistry  big disadvantage chemical and Germs can be getting in drinking at the water'source or in distributed system. 

Branches of chemistry:

• Analytical Chemistry.
• Biochemistry.
• Chemical Engineering.
• Inorganic Chemistry.
• Organic Chemistry.

Physical Chemistry.

The study of physical and composition is called physical  chemistry and change in them.

Physical properties are:

Structure of atom: in this we study how atom made.

Behaviour of matter: In this we study about how atom working.

Formation of molecule: In this we study about transfer of how molecule is used for.

Effect of temperature: In this we study how temperature effect on atom.

Organic Chemistry:

 The Study of hydrocarbon only is called organic chemistry.

Example:Methane Gas (CH4,CH3).

Inorganic chemistry: It is the branches of chemistry in which we study about with hydrocarbon is called

Inorganic chemistry:

Example: Metal, Ceramic glass,cement.

Analytical Chemistry:

It is the branches of chemistry in which we study about detection,identification,quantification ond chemical compound ,characterization is called Analytical Chemistry.

Biochemistry:

 The combination and biology and to study living matter is called biochemistry.

Chemical Engineering:

In this we study about chemical develop and design chemical manufacturing processes.And we know that it chemical engineers  apply the principle of biology,physics,and math for what to solve  problems and also include production chemicals for usage.

Example :Drugs,Food,And many others products.
