Knowledge Is Power Use...
The group is dedicated to like minded friends who would like to discuss any topic which will help us have a healthy debate and discussion and help us in becoming better human beings. Please go through the details and understand the same well before joining the group as joining the group means agreeing to the same. The knowledge thus obtained can be used for the betterment of humanity and help us in turning out to be individuals working for a common good and a better world. Respect and tolerance for others opinion and views is a basic requirement in this process members would also not make any negative comments, character defamation and use abusive language and indulge in deviant behaviour. Whoever would want to join or comment in the group would not misuse the group and stray from its objective and would not indulge in any legal cases, arbitration, suits, claim damages and the like. Topics will usually start with a write up article.

Changes are constanly occurring around us and within us,many changes occur in the environment-in the air,natural waters,land,and in organisms that thrive there.sometimes matter changes on its own likf when plants decay or a piece of iron gets rusty.you have leared in biology that plants manufacture food by photosynthesis, a chemical proccess that occurs in the presence of sunlight. The starch in palay is manufactured by this process. It undergoes more changes as it is cooke into rice cakes. As you live each day,many chemical processe take place within your body. The digestion of food involves a complex series of chemical changes.chemical reactions are involved in our thought process and how knowledge is stored in and retrieved from our brains. Several chemical changes allow your eyes to scan this page and your brain cells to translate these words into thoughts.

As you live each day,many chemical processes take place tithin your body. The digestion of food involves a complex series of chemical changes. Chemical reactions are involved in our brains. Several chemical changes allow your eyes to scan this page and your brain cells to translate these words into thoughts. Oftentimes, we change matter to make it more useful. Chemists and chemical engineers take the raw stuff of the earth-minerals,water,air,plants or animal materials,crude oil,and energy-and transform them into materials we use in daily life. |

The water in whici you bathe was chemically treated before reaching the pipes. The soap,shampoo,and toothpaste you used look very different from the raw materials(oil and minerals)from which they were manufactured in various ways. Your drinks were in plastic-lined cardboard cartons or in plastic bottles. You carry some books and notebooks-processed cellulose and plastic and electronically printed with ink. |

You Rode in hydrocarbon-fueled vehicles. The changes occurring naturally and synthetically are just to numerous to mention. |
