Physics It is easy to burst a gas-filled balloon with a needle than with a nail. It is because Gas is reactive with the needle. Needle exerts more pressure than nail on the balloon. Nail exerts more pressure than needle on the balloon. Nail is more longer than needle. Gas is reactive with the needle. Needle exerts more pressure than nail on the balloon. Nail exerts more pressure than needle on the balloon. Nail is more longer than needle. ANSWER DOWNLOAD EXAMIANS APP
