hardness of matter

The skeleton or its parts get preserved with the living matter completely disintegratin..

All around us are substances that are made of matter. Matter has mass and occupies some space. Different kinds of substances are made up of different matter. Matter can be thus classified in many ways. Two basic classifications of matter are b..

Summary - All material is made from small moving particles called atoms. Materials can be solid, liquid or gaseous, depending upon the arrangement and freedom of movement of these particles. Diffusion is the movement of particles from a place of high concentration to a place of lower concentration ..

A solid has certain characteristics: According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Solids are usually crystalline. A solid is a crystalline subst..

The evidence of the electrical nature of matter preceeded the first theories about the structure of matter. In 1832, Michael Faraday discovered electrolysis. He gave the first important clue relating electricity to matter and about the electric nature of atoms. Faraday..

A 100 mL syringe is taken whose nozzle is plugged or closed by inserting a rubber cork. The plunger is drawn out such that the whole space is occupied by air. When the plunger is pushed back into the syringe we notice that the air inside the syringe decreases i.e., it is compressed. The experiment ..

The branch of physics which deals with magnetism due to the electric current is called electromagnetism. For a long time it was hard to believe if there existed a relation between electricity and magnetism. Hans Christian Oersted observation made a discovery demonstrating a close relation..

. It was indeed a very hard decision to take. Thanappa made the right choice. I congratulate Thanappa for his humanistic approach in performing his duties. I hope that all of us will remember that people are the ones who matter most in our lives and work towards this goal. Thank..
