Questions and Answers

What is the primary reason for air to go out of the balloon but not come in?

  • The balloon material allows air to escape but not enter (correct)
  • The balloon's shape forces air to escape and prevents entry
  • The balloon surface repels incoming air molecules
  • The balloon creates negative pressure inside, pushing the air out

    • Which physical property of the balloon contributes to the phenomenon of air going out but not coming in?

  • Elasticity (correct)
  • Density
  • Temperature resistance
  • Opacity

    • What role does air pressure play in the behavior of the balloon?

  • Air pressure has no effect on the movement of air in and out of the balloon
  • Higher pressure inside the balloon forces air out but prevents entry (correct)
  • Lower pressure inside the balloon allows air to escape but not enter
  • Equal pressure inside and outside the balloon allows for bidirectional air movement
