hi friend, balloon filled with GAS and burst when we take it close to Fire due to pressure....

Answer 2

the gas in the balloon is of different composition from the gas present in the surroundings.
when we take the balloon Close To The Fire the temperature increases which results in the increase in volume of the balloon and also results in the increase of the pressure

hence it bursts.
