What produces a popping sound?
The reaction of hydrogen with oxygen is very fast. We know that heat causes gases to expand , so whenever we bring hydrogen in contact with heat it expands , it is so fast that it breaks the sound barrier and as a result we hear a 'pop' sound. Hence, the 'pop' sound occurred due to formation of Hydrogen.

If you have a heating, ventilation, and air conditioning (HVAC) system, the knocking sounds you're hearing could be from the ductwork.
What do crackles sound like?
Crackles, also called rales, are described as discontinuous, interrupted or explosive sounds. They might sound like rattling, bubbling or clicking. Fine crackles, or “crepitation,” are short, high-pitched sounds. Coarse crackles are a lower pitch and last longer.

A crackle is usually a softer, more continuous sound. Campfires crackle, a bowl of rice krispies crackle (and snap and pop), the ice underfoot could crackle perhaps. Crack is to crackle as shout is to murmur. Although one could easily imagine occasions where either word might be appropriate.
What is crackling or cracking sound?
Many times, the sound simply means air or gas bubbles have built up in the fluid around the joints and the cracking is those tiny bubbles bursting. Other times, knee crepitus can indicate early or even moderate osteoarthritis.

What gas turns lime water milky?
The sediment layer isn't entirely solid, instead trapping pockets of water among the solid material. So, when the heating element warms up, it boils the water trapped within the sediment. The hot water rises through the sediment layer and 'pops' out of the solid material, causing the popping noise that you can hear.
