Chemistry..not just chemicals…..

That’s True…

Chemistry Is Not Just About Chemicals Or Test Tubes , Molecules  Etc.

So..

What Is Chemistry ?… What Is Chemistry All About ?..What’s The Importance Of Chemistry In Every Day Life ?..What Chemistry Deals With ?

Definition of  Chemistry :

As the technology advances , as new discoveries and theories  takes place so the definition of Chemistry Changes. In general we may define Chemistry as :

Chemistry is

A branch of physical science that studies the composition, structure, properties and change of matter.

Or in simpler words , Chemistry is the study of matter, its properties, how and why substances combine or separate to form other substances, and how substances interact with energy.

Chemistry Deals With :

Chemistry deals with various topics such as , the properties of individual atoms, how atoms form chemical bonds to create chemical compounds, the interactions of substances through intermolecular forces that give matter its general properties, and the interactions between substances through chemical reactions to form different substances etc.

Chemistry As Central Science :

Chemistry is sometimes called the central science because it bridges other natural sciences, including physics, geology and biology. For the differences between chemistry and physics see Comparison of chemistry and physics.

Not Only Chemist…

Many people think of chemists as being white-coated scientists mixing strange liquids in a laboratory, but the truth is we are all chemists.

Doctors, nurses and veterinarians must study chemistry, but understanding basic chemistry concepts is important for almost every profession. Chemistry is part of everything in our lives.

Every material in existence is made up of matter — even our own bodies. Chemistry is involved in everything we do, from growing and cooking food to cleaning our homes and bodies to launching a space shuttle. Chemistry is one of the physical sciences that help us to describe and explain our world.

Importance Of Chemistry In Everyday Life :

Why chemistry is important in our everyday life..This Question clicks in mind when we are taking chemistry as our subject in 11th Standard. Attending Your 1st Day In School you may be given an homework assignment to find an answer to above question.

Have a look here at why chemistry is important.

• Everything is made of chemicals. You are made of chemicals. So is your desk. So your vehicles. So is the sun. Drugs are chemicals. Food is made from chemicals.
• Many of the changes you observe in the world around you are caused by chemical reactions. Examples include changing colors of leaves, cooking food and getting clean.
• Knowing some chemistry can help you make day to day decisions that affect your life. Can I mix these household chemicals? What are safe mosquito repellents? Will my bottled water expire?

Every material in existence is made up of matter — even our own bodies. Chemistry is involved in everything we do, from growing and cooking food to cleaning our homes and bodies to launching a space shuttle. Chemistry is one of the physical sciences that help us to describe and explain our world.

Amazing Science…..

Science is a fascinating subject with many amazing things to learn and discover.

Enjoy interesting posts and fun facts on  astronomy, chemistry , life, our natural world, animals, plants and much more.

Read on to find more posts and trivia while remembering that as the society and technology advances so too does our understanding of science and the world around us.

What is ‘fact’ today may be disproved tomorrow.What are ‘the laws’ governing our natural world today may be modified tomorrow.

New Laws will come into existence. New inventions takes place almost every day. Technology advances everyday helping us in better understanding of this world.

This whole world as we see around us is a mystery. For example The Earth we live on , is still a mystery in many sense today. The Sun around which earth revolves is still a mystery or in short we may say that  this whole universe is full of mystery.

There are more unanswered questions then answered ones. But men has not ended his curiosity and willingness to learn , study and understanding things. As the things around us changes so our understanding. Enjoy reading our Posts and other articles and get connected to blog for updates.

Organic Chemistry An Small Introduction..

Organic Chemistry

The study of all compounds that contain carbon is called organic chemistry. Carbon atoms are unique. They can combine with each other to make molecules that contain hundreds, even thousands, of carbon atoms. There are more CARBON COMPOUNDS than compounds of all the other elements put together. CARBON TECHNOLOGY uses carbon compounds to make many modern materials, from the interiors of aircraft to medicines.

a)  Carbon In All Living Things :

From butterfly wings to the petals of a flower, all living things are made of carbon compounds. All the processes that happen in living things – such as digestion, movement, and growth – are chemical reactions involving carbon compounds. It is the ability of carbon to make so many different compounds that results in the rich diversity of life on Earth.

b)  Carbon Compounds :

Many carbon compounds contain the same few elements, but in different quantities and arranged in different ways. The most important elements to join with carbon are hydrogen, oxygen, and nitrogen. Carbon atoms can form chains of just carbon and hydrogen, which are called hydrocarbons. They can also form rings of carbon, called aromatics.

Methane is a hydrocarbon. It contains one carbon atom bonded to four hydrogen atoms. The prefix “meth-” always refers to compounds whose molecules contain only one carbon atom. Methane is a natural gas. It is used in domestic central heating.

Butane gas is a slightly more complex hydrocarbon than methane. Butane contains four carbon atoms and ten hydrogen atoms. The prefix ‘but-’ always refers to compounds whose molecules contain four carbon atoms in a chain.

A benzene molecule is made of a ring of six carbon atoms, each of which is bonded to a hydrogen atom. This gas is used to make dyes and pigments. Compounds whose molecules are made of carbon rings are called aromatics as they have distinctive smells.

Alcohol And Esters :

A carbon compound called an ester gives an apple its distinctive smell. Esters are liquids with a sweet, fruity smell, and evaporate quickly. They are made when alcohol reacts with an acid. Alcohols and esters contain carbon, hydrogen, and oxygen atoms.

c)  Carbon Technology :

The carbon industry is one of the largest and most important industries because so many products contain organic (carbon) compounds. Carbon technology is vital to the production of medicines, paints, synthetic fabrics, food flavorings, plastics, cosmetics, and glues. The raw materials that are the basis for these products come from coal, crude oil, and natural gas.

Racing bikes are often made from carbon fiber because it is strong and light, and can be moulded into complex shapes. The carbon fibers are woven into a cloth which is then cut and layered in a mould. The moulded part is filled with a chemical called a resin and then baked in an oven to form the hard, tough carbon fiber material.

New medicines are made to treat specific illnesses by combining organic (carbon) compounds in new ways. Some are similar in structure to compounds found naturally in our bodies or in plants. New medicines undergo a series of tests to ensure they do not have any poisonous effects.

  

Paint pigments and the dyes that colour our clothes are mostly organic compounds. Pigments coat the surface of a material. Dyes bond with the molecule of the fabric they are colouring. The molecules of pigments and dyes often contain many rings of carbon atoms.

All plastics are organic compounds, made from recycled plastic or from the products of coal, oil, and natural gas. From flexible bags to hard chairs, plastics are light and cheap to make. Their molecules are made of long chains of carbon atoms called polymers.

Carbon Fibers :

Polyacrylonitrile (PAN) is heated to 3,000°C (5,432°F) to create thin filaments of carbon fiber. This material is fireproof and five times lighter than steel, yet twice as strong. Carbon fiber has many uses, such as in lightweight sports equipment, car body panels, construction pipes, and on the wings and nose of space shuttles.

Amazing And Updated Outer Space Facts

Outer Space Or Just Space Has Always Surprised Humans Since Ancient Times.

Outer space is just what its name implies. It is the void that lies beyond the uppermost reaches of the atmosphere of Earth and between all other objects in the universe. Although it is a void, outer space may be thought of as an environment. Radiation and objects pass through it freely.

Read The Facts and Enjoy

1 ) We Are In Motion Every Time…..

When you think you’re standing still remember this fact. Even though you don’t feel it, our entire local group of galaxies is moving at about one million miles per hour toward another galaxy group called the Virgo Cluster.Our Galaxy – the Milky Way is spinning at a rate of 225 kilometers per second. In addition, the galaxy is travelling through space at the rate of 305 kilometers per second. This means that we are traveling at a total speed of 530 kilometers (330 miles) per second. That means that in one minute you are about 19 thousand kilometers away from where you were. Scientists do not all agree on the speed with which the Milky Way is travelling – estimates range from 130 – 1,000 km/s.  [Source : Listverse.com]

2 ) Without A Telescope…..

The farthest you can see with the naked eye is 2.4 million light years away! (140,000,000,000,000,000,000 miles.) That’s the distance to the giant Andromeda Galaxy. You can see it easily as a dim, large gray “cloud” almost directly overhead in a clear night sky.

3 ) First Animal In Outer Space…..

The first animal sent up to outer space was a dog. Laika was a Soviet space dog who became one of the first animal in space, and the first animal to orbit the Earth. Laika, a stray dog from the streets of Moscow, was selected to be the occupant of the Soviet spacecraft Sputnik 2 that was launched into outer space on November 3, 1957.

4 ) Galaxies In Universe…..

There Are More Then 100 Billion Galaxies In Universe. Of which Andromeda Galaxy Is Nearest To us. Andromeda Galaxy is 2.537 Million Light Years Away From Earth.

5 ) Our Sun…..

The Sun is the largest object in our solar system. Comprising Of 98%  of our solar system’s total mass.

6 ) The moon is drifting away from Earth…..

Every year the moon moves about 3.8cm further away from the Earth. This is caused by tidal effects. Consequently, the earth is slowing in rotation by about 0.002 seconds per day per century. Scientists do not know how the moon was created, but the generally accepted theory suggests that a large Mars sized object hit the earth causing the Moon to splinter off. [Source : Listverse.com]

7 ) The Sun loses up to a billion kilograms a second due to solar winds…..

Solar winds are charged particles that are ejected from the upper surface of the sun due to the high temperature of the corona and the high kinetic energy particles gain through a process that is not well understood at this time. Also, did you know that 1 pinhead of the sun’s energy is enough to kill a person at a distance of 160 kilometers? [Source : Listverse.com , Planet Science]

8 ) If two pieces of metal touch in space, they become permanently stuck together

This may sound unbelievable, but it is true. Two pieces of metal without any coating on them will form in to one piece in the vacuum of space. This doesn’t happen on earth because the atmosphere puts a layer of oxidized material between the surfaces. This might seem like it would be a big problem on the space station but as most tools used there have come from earth, they are already coated with material. In fact, the only evidence of this seen so far has been in experiments designed to provoke the reaction. This process is called cold welding. For those who still don’t believe it,  please lookup Wikipedia’s article on Cold Welding.       [Source : Listverse.com ]
