Question

Why does hydrogen gas burn with pop sound?

Answer 1

Hydrogen Gas:

• The non-metal hydrogen has the chemical symbol $\mathrm{H}$.
• $H_2$ is the molecular formula for Hydrogen gas.
• Hydrogen has long been acknowledged as a practical and environmentally friendly fuel. It is ideal for internal combustion engines in automobiles and can be stored as a compressed gas or a liquid.
• Hydrogen is a non-toxic and non-carcinogenic element. Coal and water can be used to make hydrogen. It is a necessary component in the manufacture of polyurethane polymers.

Reason for Hydrogen Gas Burn With Pop Sound:

• Hydrogen gas is inflammable in nature. The squeaky pop sound of a bubble of $H_2$ is actually a small explosion which occurs when it comes in contact with oxygen and heat.
