QUESTION
What is the direction of the air when the balloon deflates?
ANSWER
1.) When we let go of the end, the air rushes out and pushes against the air around the balloon to move it in the opposite direction.
extra ans.
2.) The elasticity of the balloon contracts the air out through the opening with sufficient force and the resulting pressure creates a thrust which propels the balloon forward as it deflates.
3.) The gas particles move freely within the balloon and may collide with one another, exerting pressure on the inside of the balloon.
