Why Do Balloons Explode When Left in the Sun?

Why did some balloons hanging outside Ella's house explode after a few hours?

The balloons hanging outside Ella's house exploded after a few hours because they were in the sun for a long period of time.

Explaining Balloons Exploding in the Sun

Balloons exploding in the sun is a common phenomenon that can be easily explained by science. When balloons are left in direct sunlight for an extended period of time, the air inside them heats up and expands. This expansion causes the pressure inside the balloon to increase to a point where the balloon can no longer contain it, resulting in the balloon popping or exploding. When balloons are exposed to sunlight, they absorb heat from the sun, causing the air molecules inside the balloon to move faster and increase in temperature. As the temperature of the air inside the balloon rises, the molecules move more vigorously and spread out, increasing the pressure inside the balloon. If the pressure inside the balloon becomes too high, the balloon's material, typically latex or rubber, may not be able to withstand it and eventually gives way, resulting in an explosion. The sudden release of pressure is what causes the balloon to burst. In Ella's case, the balloons hanging outside her house exploded after a few hours because they were continuously exposed to direct sunlight, which caused the air inside them to heat up and expand. Eventually, the pressure inside the balloons became too great, leading to their explosion. To prevent balloons from exploding when left outside in the sun, it is advisable to keep them in a cool and shaded area, away from direct sunlight. This will help maintain the air inside the balloons at a stable temperature and pressure, reducing the risk of them popping or exploding. In conclusion, the reason why balloons hanging outside Ella's house exploded after a few hours was due to the prolonged exposure to the sun, which caused the air inside them to heat up, expand, and create excess pressure that the balloons could not contain, leading to their explosion.
