Study the following examples - a) Water stored in a reservoir is capable of rotating turbines, which are kept at a lower level i.e, water stored in a reservoir possesses energy. b) If you hit a nail hard with a hammer the nail gets fixed whereas if the hammer is just placed on the nail, t..

The above resources can be classified as renewable or non-renewable. Some resources are constantly produced on the earth and are known as renewable resources. Others are not replenished and are called non-renewable sources. Resources Renewable resources Non-renewable resources Solar power Wood Hydr..

. The various energies which contribute towards internal energy are: (a) Translational energy of the molecules (E t ) (b) Rotational energy of the molecules (E r ) (c) Vibrational energy of the molecules (E v ) (d) Electronic energy (..

Judicious use of Energy - In order to live and enable ourselves to do everyday work we need energy. The prosperity of a country depends upon the availability of energy. Huge amount of electrical energy is used to run the air conditioners, cold storage and oth..

The unit in which atomic and nuclear masses are measured is called atomic mass unit (a.m.u). 1 a.m.u is defined as 1/12 t h of the mass of an atom of 6 C 1 2 isotope. It can be shown that 1 a.m.u = 1.66 x 10 2 7 kg. According to Einstein, mass energy equivalence E = mc 2 Where m = 1.66 x ..

India produces only half of the national requirement of petroleum products and it imports the rest from other countries. Natural gas is the most popular petroleum product. During last two decades, the consumption of natural gas resources have increased tenfold. If we need to save fossil f..

Growing consumption and non renewablity fossil fuel necessitate the conservation of this natural resource of to help in this effort many measures have been advocated. 1) Use of oil should be minimized so as to save it for future use. Public transport should be used as far possible. 2) Mo..

is a natural gas. It is produced from animal, water and weeds and other plants. India comes first in developing and using biogas technology. It is cheap, non-polluting and labour-saving fuel. Biogas can be used for cooking, lighting, and in vehicles. Solar energy, wind en..

Introduction - All living organisms require a continuous supply of energy for carrying out various functions. The main source of energy for all the functions, in all living organisms is cellular respiration. Cellular respiration is an energy releasing, enzymatically co..

Question: Explain the three R's in the conservation of environment? Answer: The three R's refer to Reduce, Recycle and Reuse. Reduce: Use less electricity by switching off unnecessary lights and fans, save water by repairing leaky taps, do not waste food. Recycle: Materials mad..
