Answer 1

Dear Student,
Yes, hydrogen is the only gas which burns with a pop sound. It is one of the test to identify hydrogen gas. Hydrogen is a combustible gas and produces large amount of energy when it combusts. This energy is much larger than other combustible gases like gasoline, etc. It is this heat which causes sudden expansion of air in the test tube and produces a pop sound.
