Is this also considered an explosion?

2009-03-28View Original

Thread Content

It is a phenomenon that occurs when liquid nitrogen vaporizes. When liquid nitrogen is vaporizing and low-pressure steam is used, a \"popping\" sound can be clearly heard inside the vaporizer. I would like to ask everyone: is this also a type of gas explosion? Is it a common phenomenon that occurs when there is a large temperature difference when heating low-temperature liquids?

I think it can be like the process of water boiling – a sound produced by gases bubbling up within the liquid.

I suspect it might be due to excessive local temperature, causing the small bubbles formed inside to burst and generate sound, but I haven’t verified this

Is it boiling over? In a situation like the one you described, boiling over is very likely to occur

I don’t think so; it boils when the pressure reaches the saturation vapor pressure at that temperature.

It’s somewhat similar to that – it gives a feeling akin to the violent bubbling that occurred during experiments in the past when no zeolite was used. There’s a very sharp and loud noise coming from the vaporizer, like that of small firecrackers.
