Question

a balloon went kept in Sun breast after sometime why​

Answer 1

Storing Uninflated Balloons So They Last. Balloons should be stored away from heat, light and exposure to the air. ... I used to keep my balloon supply in the freezer, and there were times when I'd have the same gross in there for a year, or more, and they always worked just fine, even after all that time.

Answer 2

It is burst not breast, It is because the kinetic energy increase in the gas molecules with the increase in tempreature and because of this the balloon expands and bursts.
