Is Matter Around us Pure - Summary Matter is anything that occupies space and has mass Element is a pure substance, which can neither be decomposed nor built from simpler substances by any physical or chemical means. It contains only one kind of atom. Broadly speaking,..

Summary - Matter is anything that occupies space and has mass. Element is a pure substance, which can neither be decomposed nor built from simpler substances by any physical or chemical means. It contains only one kind of atom. Broadly speaking, elements can be divided into meta..

Summary - The phenomenon of interference, diffraction and polarization can be explained by the wave theory of light. But the photo electric effect can be explained only using 'photon theory'. That is using particle nature of light. The experimental study of photoelectric effect led to the..

Ammonia is produced by decay of plant and animal tissues. Nitrogenous organic matters like urea in the urine and excreta of animals get acted upon by bacteria releasing ammoni..

According to Dalton's atomic theory, all matter is made up of very small particles called atoms, which cannot be further divided and have independent existenc..

Physics is a branch of science that deals with the nature and natural phenomena. The study of physics finds great importance in our day-to-day life. The laws, formulae and calculations of physics are not merely things to be remembered from the point of view of exams, but their knowledge inc..

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 on..

Electric charge is a basic property of all matter. Unlike charges attract, like charges repel. Conductor allow flow of electric charges through them while insulators don't. Electric charges have three basic properties (a) Additivity (b) Quantisation (c) Conservation Coulomb's law:..

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. When a ..

Ammonia is produced by decay of plant and animal tissues. Nitrogenous organic matters like urea in the urine and excreta of animals get acted upon by bacteria releasing ammonia. Ammonia is manufactured by Haber's Process by the reaction of 1 volume of nitrogen gas and 3 volumes of hy..
