Why is there a pop sound when hydrogen is burned?

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.

What is causing the pop sound?

The fluid contains the gases oxygen, nitrogen, and carbon dioxide. When you pop or crack a joint, you stretch the joint capsule. Gas is rapidly released, which forms bubbles. In order to crack the same knuckle again, you have to wait until the gases return to the synovial fluid.

What does the pop sound indicate in a reaction explain with an example?

Hint: Sodium metal is very reactive. Sodium reacts vigorously with oxygen and water. A large amount of heat is generated in the reaction. To test for the release of hydrogen gas, a lighted splint is placed over the reacting metal- if it “pops” then hydrogen gas is present.

What is the sound of a hydrogen gas pop?

The pop is the sound of the rapidly expanding water vapor and heated hydrogen, slamming into the surrounding air. , Researching Renewable Energy and Technologies. How many kWh can you get from burning 1 litre of hydrogen gas?

Which gas does not give pop sound when it burns?

The pop sound comes from the small explosion formed by the burning of Hydrogen with oxygen. Other common gasses, such as water vapour, nitrogen, and carbon dioxide will not burn with oxygen, so will not give a pop. Was this answer helpful? Was this answer helpful?

Why does a balloon pop when it is filled with hydrogen?

The pop sound you hear is a mini shock wave. If the H2 is collected in a balloon about 10–15cm in diameter the pop become a very loud “bang”. Hydrogen burns with a “pop” sound because it reacts with compounds or elements around it to release energy.

What happens when hydrogen is burned in air?

If the hydrogen is let to burn openly in air it will not form a “pop” sound but fire will be seen. , Born sceptical. One is a pure sample of hydrogen, which will not make a pop sound as it will not burn in the absence of oxygen. The second is a mix of hydrogen and air, and ignites with a pop.
