Summary Matter - anything which has mass, occupies space and can be perceived by our senses. Law of conservation of matter - matter can neither be created nor destroyed. The states of matter are solid, liquid gas, plasma and super cooled solid. ..

Is Matter Around us Pure Matter can be broadly divided into two major groups, 'Pure' and 'Impure'. In chemistry, the term 'purity' acquires quite a different meaning from what we understand it to be in our day-to-day life. Normally, when we refer to ..

Pure Substances The distinctive features of pure substances are: A pure substance is composed of the same kind of particles e.g. hydrogen, oxygen, water, sodium chloride, etc. A pure substance is homogeneous, irrespective of its origin or method of p..

Physical and Chemical Changes Matter undergoes certain changes as a result of the application of energy. Water from saltpans on the seacoast dry up, leaving behind salt; water from the sea evaporates to from water vapour, which convert into clouds and then condense to form rain. Glaci..

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 i..

Separation of the Constituents of Mixtures The separation of the various constituents of different mixtures depends on the properties of the constituents. Some of these properties are size, density, magnetic nature of particles, solubility, miscibility, differences in boiling and melting points..

Characteristics of Particles of Matter - According to the dynamic particle model all states of matter are made up of tiny particles and matter as a result is an aggregation of very small particles. Nevertheless, the state of aggregation of particles is different in dif..
