Why does not waterballon brust when we put it on fire?

Answer 1

A water balloon doesn't burst when placed over a flame because the water inside absorbs the heat, preventing the rubber from reaching its melting point. The water acts as a heat sink, dissipating the heat away from the balloon's material. As long as there's enough water to absorb the heat, the balloon can withstand the flame without bursting. However, if the water evaporates or if the balloon is exposed to direct flame for too long, it can eventually burst.
