What causes pressure inside a helium balloon?A.The helium atoms stick to the surface of the balloon and increase its weight.B.The helium atoms expand and press on the surface of the balloon.C.The helium atoms bounce off the surface as they move inside the balloon.D.The helium atoms exert an electrostatic force that pushes the surface outward.

If a balloon is squeezed, what happens to the pressure of the gas inside the balloon?A.It stays the same.B.The pressure depends on the type of gas in the balloon.C.It increases.D.It decreases.

What happens to the pressure inside a balloon when someone squeezes it (i.e., decreases its volume)? Explain what is happening to the gas particles.Answer text Question 2Rich text editor

When you squeeze a balloon, it gets smaller and the air inside pushes harder against the walls. This happens because there's less room for the air to move around, so it bumps into the balloon more often, making the pressure increase

The string of a helium balloon slips from your hand, and the balloon rises up into the air. When this happens  the balloon rises continually but slows down due to the effect of viscosity.   the balloon rises until it reaches an altitude where its weight equals that of the same volume of air.   the balloon rises until it reaches an altitude where the air and helium densities are equal.   the balloon rises indefinitely because helium is lighter than air.
