Materials in Our Daily Life : 95 : 21 Materials in Our Daily Life The basic aim of science is not only to study and understand natural phenomena but also to use this knowledge to make our lives more comfortable. Science and technology have enabled us to develop more economical and convenient methods to recover useful materials from nature and to put them to various uses. Chemistry has enabled us to synthesize new materials which have desired properties‚ thus‚ making them even better than natural

transportation of daily necessities). Exponential growth of India’s economy has given rise to an exponential need for energy. Fossil fuels (coal‚ oil‚ natural gas) are the most commonly used fuel by people. Fossil fuels have been formed from decaying plant and animal matter under pressure for many million years. The fuel that has been formed in millions of years is being used at an alarming rate: As citizens‚ what can we do about it? We can become more educated about Oil Conservation and act responsibly

Importance of chemistry in our daily life Importance of chemistry in our daily life Everything is made of chemicals. Many of the changes we observe in the world around we see that caused by chemical reactions. Chemistry is very important because it helps us to know the composition‚ structure& changes of matter. All the matters are made up of chemistry. In our every day like various chemical are being used in various from‚ some of those are being used as food‚ some of those used

questions‚ we must find out where in our daily activities‚ chemistry is involved and how it benefits us. Without realising‚ chemistry is used in all part of our lives and some of its features are more recognised by specific user groups‚ for example a kid wouldn’t be interested in how chemistry makes their fathers shaving foam more lubricant. I believe looking at the problem from this perspective would be more ideal. We all start life as a baby and a our main role is to grow‚ in other

Energy Conservation SCI/275 Energy conservation is so important. Why you ask? Because of the limited amount of nonrenewable energy sources on Earth‚ it is important to conserve our current supply or to use renewable sources so that our natural resources will be available for future generations. Energy conservation is also important because consumption of nonrenewable sources impacts the environment. Specifically‚ our use of fossil fuels contributes to

Oil And Gas Conservation Oil and gas conservation effects your daily life in several ways: 1) As you conserve you own consumption of oil and gas‚ your fuel bills are reduced 2) Oil and gas conservation tends to reduce demand for oil and gas and this‚ in turn‚ tends to lower the price of fuels and products made from oil and gas (like plastics) to the consumer. 3) Conservation of oil and gas usually also means less burning of them as fuels‚ which‚ in turn reduces the amount of pollutants

Conservation of matter and energy Introduction to conservation of matter and energy The conservation of matter and energy means that the total amount of energy and the total amount of matter is always constant in a given closed‚ isolated system. In other words‚ neither energy nor mass can be created or destroyed in any physical or chemical process. Formation of the law of conservation of matter and energy Until the discovery of mass - energy equivalence by Albert Einstein in 1905‚ conservation

SOURCES OF ENERGY Energy can neither be created nor destroyed. Energy can only be converted from one form to another. E.g. if we drop a plate from a height‚ the potential energy of the plate gets converted mostly to sound energy when it hits the ground‚ chemical energy in the wax is converted to heat energy & light energy on burning. The total energy during a physical or chemical process remains the same. In the above examples‚ energy in the usable form is dissipated to the surroundings in less

FREE FALL AND CONSERVATION OF MECHANICAL ENERGY ABSTRACT Free fall is defined as the ideal falling motion of an object that is subject only to the earth’s gravitational field. To prove the law of conservation of energy‚ the free fall motion of an object can be represented through 3 different analyses; position of the object vs. time‚ velocity of the object vs. time‚ and acceleration of the object vs. time. It is observed in this ball toss experiment‚ at any point during the free fall period‚
