SUBJECT : CHEMISTRY UNIT : CHANGES

CHANGES Various types of changes takes place around us. Everything in the universe undergoes change. Some changes are here Physical Changes Chemical Changes

PHYSICAL CHANGE Temporary changes in which no new substances are formed are called physical changes.

CHEMICAL CHANGE Permanent changes in which new substances are produced are called chemical changes
