A balloon filled with air is slowly taken from sea level to higher altitudes. Which of the following can be the most suitable observation?
The balloon stretches out and bursts at a point.
At sea-level, the internal pressure of the balloon tries to stretch out the balloon and the atmospheric pressure tries to shrink it in. As the balloon goes up, the atmospheric pressure reduces. So, the internal pressure dominates and it stretches out the balloon. As we continue going up, atmospheric pressure will keep on reducing, consequently, the balloon will keep on stretching and will burst at some point.
