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 ..

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 r..

>Filtration is a more effective method of separating an insoluble solid from a liquid. A soluble solid can be obtained back from a liquid in which it dissolves by the process of evaporation. Distillation is employed to separate and re-obtain both the solute and the solvent from a solution. Fraction..

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. ..

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..

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, elements ..
