bases in classification of matter

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 matterh..

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 metals..

Based on its physical characteristics, matter is divided into solids, liquids and gase..

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..

This theory explains the physical properties of matter in terms of motion of its molecules. According to this theory, every substance (solid, liquid or gas) consists of a large number of minute particles called molecules . A molecule may be defined as the smallest particle of a substance ..

The fourth state called plasma refers to the super heated gaseous state. This is a mixture of electrons and positively charged ions with unusual properties. It is found at extremely high temperatures such as interiors of the sun or stars. Astronomers reveal that 99% of all matter in the u..

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

The classification of matter into three different states, namely solid, liquid and gaseous state is termed as the physical classification of matter. Most properties of solid, liquid and gases that can be observed with our sense organs are called as 'mac..
