A Balloon Question

A Balloon Question

A Physics student blows up two initially identical balloons. However the student blows up one balloon to a larger size than the other. The student then carefully connects the openings of the two balloons together. (See diagram below). The question is, when the two balloons are connected, what happens?

balloon

  • A. Nothing happens, the two balloons are both surrounded by air, therefore at the same air pressure -- so nothing will happen, the size of the balloons does not change.
  • B. The larger balloon has more air in it, so it will decrease in size as it forces air into the smaller of the two balloons, until both are the same size.
  • C. The smaller balloon will force air into the larger balloon until nearly all the air from the smaller balloon will be in the larger balloon.
  • D. I once saw a clown blow up balloons and make little animals.
