Periodic and Non Periodic Changes | Physical and Chemical Changes | Class 8 Chemistry

These are the changes that keep happening at certain intervals of time. Time is the biggest example of it. Every day we get twenty-four hours and after the periodic interval, the time on the clock is repeated again. Another example of this can be that of weather. They keep coming after a certain interval of time.
