Why hydrogen gas produces a pop sound when we bring a burning matchstick near it?

A lot of energy is released by hydrogen when it combusts. And this gaseous mixture contains hydrogen, oxygen and water vapor liberated from the reaction. This quick expandation of gas molecules causes a break of the sound barrier. And because of this explosion we hear the pop sound of hydrogen burning.

When a burning matchstick is brought near the dash gas it burns with a pop sound?

The ‘pop’ sound comes due to the evolution of hydrogen gas.

What happens when hydrogen gas is ignited with a burning matchstick?

When the hydrogen gas produced is ignited with a burning matchstick, the gas burns with a ‘pop’ sound and a small explosion takes place.

What burns with a pop sound?

Hydrogen is a gas that burns with a ‘pop’ sound.

What does a pop sound indicate when a burning matchstick is brought near the mouth of the test tube?

A piece of aluminium foil is treated with dilute hydrochloric acid or dilute sodium hydroxide solution in a test tube and on bringing a burning matchstick near the mouth of the rest tube, a pop sound indicates the evolution of hydrogen gas.

What happened when you lighted the matchstick?

Stored inside the match head is another chemical called “potassium chlorate”. When it gets hot, it releases a lot of extra oxygen and heat. This makes the match head burn quickly and strongly. When you put it all together – the heat, the fuel, and the oxygen – you get a flame!

Does hydrogen burns with pop sound?

The hydrogen gas burn with a pop sound because of the presence of the impurities. Also, the reaction between the hydrogen and oxygen results in the squeaky pop sound.

Why the hydrogen gas has a pop sound?

Hydrogen burns with a “pop” sound because it reacts with compounds or elements around it to release energy. The energy released has kinetic energy that expands and rushes out of the test tube to give rise to the “ pop” sound.
