I have the same question:
Helium gas is added to a balloon already partially filled with helium gas. the balloon inflates because the
1) Molecules in the balloon have become larger
2) Molecules are moving faster in the balloon than in the cylinder.
3) Helium molecules are heavier in the balloon than in the cylinder containing the gas.
4) Helium molecules do not collide with each other.
5) Extra helium molecules exert increased pressure in the balloon
) Extra helium molecules exert increased pressure in the balloon.
balloon thought it was getting a promotion to blimp!
additional helium gas increases the pressure inside the balloon.
When helium gas is added to a balloon that is already partially filled with helium gas, it causes an increase in pressure inside the balloon. This increase in pressure is due to the ideal gas law, which states that the pressure of a gas is directly proportional to its temperature and the number of gas molecules present, while inversely proportional to its volume.
The additional helium gas molecules have the effect of increasing the number of gas molecules inside the balloon. As a result, the pressure inside the balloon increases because there are more gas molecules colliding with the balloon walls, creating a greater force per unit area.
The increased pressure acts on the elastic material of the balloon, causing it to expand and inflate. This effect is similar to how blowing air into a balloon with your mouth causes it to inflate; the exhaled air, in this case, acts as the additional gas increasing the pressure within the balloon.
In summary, when helium gas is added to a partially filled balloon, the increased number of gas molecules increases the pressure inside the balloon, causing it to inflate.
