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