Question

On a sunny day, Rahul observed a balloon burst by itself from the bunch of balloons kept on the balcony. What could be the reason ?

Answer 1

• Since it's a sunny day, the air inside the balloon would be getting hot.
• Also we know that air expands on heating.
• Thus, the molecules of air inside the balloon would be colliding with the surface of balloon thereby increasing the pressure from inside, as shown in the image.
• This bursting of balloon is due to expansion of air on getting hot.
