Question

Rajesh took two balloons and filled one with air and the other with water. He left the balloons out in sunlight. In a little while,
the balloon filled with air burst. Why did this happen?Why didn't the other ballon burst?​

Answer 1

Answer:

The answer is due to the following

Explanation:

When the balloons were kept in open sunlight, the sunlight heated up  the balloons. So, the balloon filled with air burst because of the heat on the surface of the balloon, but the balloon filled with water did not burst. This is because, the water inside the balloon caused the heated surface of the balloon to cool and thus, the balloon did not burst even when it was exposed to sunlight.

Answer 2

Answer:

the second balloon did,nt burst because the first balloon was filled with air and by the heat of the sun the thermal expansion happened but it didn't happen in second balloon because it was filled with water which is cooler so the surface cannot be heated
