ICSE Class 8 Answered
What will happen if an inflated balloon is brought near a lighted bulb ? Why? Is it a physical or chemical change?

Expert Answer
A bulb produces heat, when a ballon is taken near a candle, the heat causes the air molecules in the balloon to vibrate and they expand hence the size of balloon increases and it bursts. Bursting of the balloon is an irreversible physical change.
