Dear Student,
◆ Answer -
Hydrogen gas makes a pop sound if exposed to a lighted matchstick.
● Explaination -
- When hydrogen gas is exposed to air, it reacts with oxygen to form water vapor.
- So if lighted matchstick is taken near hydrogen gas, it will heat the molecules of water vapor and expand them.
- Some of the molecules burst while expanding which causes a pop sound.
Thanks dear. Hope this helps you...
