5 classification of matter

Classification of Matter - Matter can be classified into different categories depending upon their physical or chemical natur..

All matter consists of atoms and molecules. Each of these atoms and molecules has certain amount of energy. The level of this energy decides the state in which the matter exists. When heat energy is supplied to matter, this energy level rises. As a result of this, sta..

Electricity and Matter - It is important to know the atomic picture of matter. The basic unit of all matter is an 'atom'. Each atom consists of a small core called nucleus which accounts to most of its mass consisting of positively charged protons and neutral neutrons ..

Wave Nature of Particles - The suggestion that matter may have wave like properties was first put forwarded in 1924-1925 by Louis De Broglie. He argued that if light, which consists of waves according to classical picture, can sometimes behave like particles, then it should be possible fo..

States of Matter - All matter consists of atoms and molecules. Each of these atoms and molecules has certain amount of energy. The level of this energy decides the state in which the matter exists. When heat energy is supplied to matter, this energy level ris..

Today the fact that all matter is made up of atoms is universally accepted. Realisation of the atomic constituents of matter began in 1828 when Scottish botanist Robert Brown observed a random ceaseless motion of pollen grains suspended in a liquid. Many macroscopic proper..

Introduction..

Summary - The science of magnetism is old. It has been known since ancient times that magnetic materials tend to point in the north-south direction: like magnetic poles repel and unlike ones attract; and cutting a bar magnet in two leads to two smaller magnets. Magnetic poles cannot be isolated. Wh..
