Why does a balloon taken near a candle burst?
Answer:
When a balloon is brought near a candle the molecules heat up and the balloon starts expanding. When the balloon no longer can expand it bursts.


#2

When the balloon is brought near to a heating source eg candle, the temperature of the air rises causing it to expand. Since the balloon has reached its elastic limit it nolonger expand hence bursting
