Question

leave one baloon in the sun and one in freezer for an hour what will happen?

Answer 1

I think other balloon in the sun will blast earlier than in cold

Answer 2

The air inside the balloon and the rubber of the balloon kept in the sun will exp pans this will cause an increase in its size and would finally burst.

Whereas the balloon inside the freezer will shrink in size because of the contraction of air and rubber of the balloon.

Hope it helps.
