Air pollution


  As we know that Air pollution is basically the presence of foreign substance in air in excessive concentration which adversely affects the well being of the individual or cause damage to property. Wherever we live, the air is contaminated to some degree by human activity.The earliest pollutants noted in the atmosphere were of natural origin ; like smoke , fumes, ash, and gases from volcanoes and forest fires or sand and dust from with storms or any other natural sources. But real problem arise when human induced or anthropogenic source started emitting pollution. Which are not good for human being.
  According to WHO ( world health organization) is defined as "the substance put into air by human activity which directly effect to his health, vegetable, property etc".
We have a many historical overview of Air pollution some are given below ;
1. London smog in Dec. 1952 coal induced smog is formed by interaction of sulphur dioxide, smoke and water to form sulphuric acid mist approx 4000 people died in last five days in this air pollution disaster.
2. Meuse valley, Belgium a strong atmospheric inversion got settled over the Meuse valley on Dec. 1, 1930 due to effluent from several companies in valley, like SOx and soot were trapped in the stable atmosphere, 63 persons died and several hundred other are become ill due to this disaster.
And many other example of Air pollution disaster are Donora, Pennsylvania, Pittsburgh, los Angeles and bhopal also under fallen this category.
Air pollution causes irreversible damage to young children's brain, says a new unicef report.air pollution decrease the I Q level and loss memory of young children according to report.  So first of all we will have to understand the whole problem and after that we will search solution of this problem.

Introduction of Water, impact of water pollution, uses of water and impurities in water.

                                  WATER 1. Water is an important gift of nature for all the living things. As it is used in all types of metabolic activities and house hold works. It may be defined as “Clear, transparent, odourless and tasteless liquid. Chemically it is made up of two atoms of Hydrogen and one atom of Oxygen.      2. In day to day life, required potable water means should be tasteful, aesthetically pure and wholesome. But due to presence of some chemicals, biological and microbes it’s become unfit for drinking and for other uses.

Properties of Fluids

Image
We know about fluid and students every fluid(liquids, vapours, gases) has definite properties which help us to describe its physical condition. Such properties are called properties of fluid. It also  helps us to analysis fluid flow problem. PROPERTIES OF FLUIDS There are main properties of fluids following :- 1. Density or Mass Density:- It is the ratio of mass of a fluid to its volume. It is de noted by ρ( ro ).     Mass Density,.   p = Mass of fluid/volume of fluid                                  =m/v SI Unit of density or Mass Density is Kg/cubic meter.   The density of water is 1000kg/cubic meter or 1 gm/cubic centimeter. 2. Specific Weight:- It is defined as the ratio of the weight of a fluid to its volume. It is denoted by 'w' and is also called weight density.          w =.       Weight of fluid/volume of fluid                 = mass of fluid ×g/volume of fluid               =     Density of fluid× g.               =.   ρg Unit of specific weight i

Introduction of Thermodynamics.

Image
In this post we will discuss about thermodynamics. so let's start. Thermodynamics is the branch of science which deals with the transformation of energy of all kinds from one form to another form and we can also say that it is mainly the study of heat and work effect. In the study of thermodynamics we read, basically four laws : the zeroth, the first, the second, the third law of thermodynamics. The laws of thermodynamics apply to the matter in bulk and not to individual atoms or molecules.these laws are based on a large number of experimental observation  and logical reasoning like all physical laws(Boyles, charles, etc). The laws of thermodynamics have no mathematical proof and have not so far violated. So, why do we study thermodynamics? or what is the utility of this subject?   Basically thermodynamics tells us whether a given process(including chemical reaction) is possible or not, under a given set of condition (e.g. temperature, pressure, etc).It provides infor
