You Are Holding Two Helium Balloons, a Large and a Small

question 27

Multiple Choice

You are holding two helium balloons, a large and a small balloon. How do the pressures of the helium compare?

• A) The pressure in the large balloon is greater than the pressure in the small balloon. This is best explained by the fact that there must be more moles of gas in the large balloon, thus greater pressure.
• B) The pressure in the small balloon is greater than the pressure in the large balloon. This is best explained by the fact that as the volume of a container decreases, the pressure of the gas increases.
• C) The pressure in the large balloon is greater than the pressure in the small balloon. The fact that there is a greater pressure in the balloon explains why the volume is larger; as the particles push more on the inside, the volume increases.
• D) The pressures are essentially the same and less than atmospheric pressure.
• E) The pressures are essentially the same and equal to atmospheric pressure.
