Identify why a balloon was stretched over the top of the conical flask.It has no purposeTo show how heat affects the particles of rubber in the balloonTo help show that a gas is formedTo help show that a liquid is formed

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

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.

What effect will the heat have on the air inside the bottle/balloon?*1 pointThermal contraction.Temperature decrease.Thermal expansion.Change in state.
