Question

Why is an inflated ball heavier than a deflated one?

Answer 1

Answer:

WHENEVER WE SEE AN INFLATED BALL AND A DEFLATED ONE, MASS OF THE INFLATED ONE IS MORE BECAUSE THE ONLY DIFFERENCE BETWEEN THE INFLATED AND DEFLATED IS THAT INFLATED HAS AIR IN IT WHEREAS THE DEFLATED DOESN'T HAVE. WE ALSO HAVE DONE A ACTIVITY IN EARLIER CLASSES TO SHOW THAT AIR HAS ITS OWN MASS.
