Answer 1

Changes which take place in a definite interval of time are called periodic changes whereas changes which are irregular and not determined with definite time are called non periodic changes.

Day and night, changing phases of the moon, beating of heart, clock striking an hour are all examples of periodic motion whereas water becoming ice, burning of matchstick etc are non periodic changes.
