Changes occur everywhere, every moment around us. Everything in the world is subject to change. There are five types of changes. 1. Chemical and physical changes. 2. Reversible and irreversible changes. 3. Desirable and undesirable changes. 4. Periodic and non-periodic changes. 5. Slow and fast changes. Chemical changes: That change the chemical composition of the material. Physical change: That are temporary and do not change the chemical composition of the material. They change only the state, colour, and texture. Reversible chages: They can be reversed. Irreversible changes: They cannot be reversed. Desirable changes: Which are desired Undeirable changes: Which are'nt desired. Periodic changes: Which happen after a regular intervals. Non-periodic changes: Which happen irregular of any specific interval time. Slow changs: Which take a long time to occur. Fast changes: Which happen quickly. -Param Gupta, Std. 6, Victorious Kidss Educares
