electrical in classification of 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 and surrounded by lighter negativel..

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 ..

Introduction - 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 macroscop..

The important differences between electromagnetic waves and matter waves are given below: Electromagnetic waves Matter waves Electromagnetic are associated with electric and magnetic fields perpendicular to each other and to the direction of propagation ..

When an electric current is passed through the filament of a bulb, the filament starts glowing and the glow stops as soon as the current is cut off. The chemical composition of the filament does not alter in either stat..

Energy exists in various forms such as mechanical energy, heat energy, chemical energy, electrical energy, light energy and nuclear energy. According to the law of conservation of energy, energy can be transformed from one form to another. In our daily life we use many devices where the h..

Introduction - Electricity is one of the most important sources of energy. Lights, fans, motors, radios and television are some common appliances which work on electricity..

Certain reactions take place with the help of an electric current. Example: Decomposition of water (acidulated) to give hydrogen and oxygen gas. ..
