Please help rewrite my answer to a question of Newton's third law of motion:Q: You blow up a balloon and pinch the open end closed. Predict what...

Newton's third law states that when two bodies interact,
with the first body exerting a force F on the second, the second body also exerts a
force with an equal magnitude on the first. The direction of the two forces is opposite
to each other.

When air is filled in the balloon, it
expands with a potential energy getting stored in the skin of the balloon that is
capable of being stretched. Providing an exit for the air to escape converts the
potential energy stored in the skin of the balloon to kinetic energy of the air. As the
air is pushed out with a force exerted by the balloon, it exerts a force equal in
magnitude and opposite in direction on the balloon. This force pushes the balloon in a
direction opposite to that in which the air is
escaping.

The force exerted on the air which pushes it out
can be referred to as the action and the force it exerts on the balloon is the
reaction.
