wait what, how does that work? like theyre underwater but its hotter than the sun?? Username relevant to my inability to understand this btw
Oxygen is flammable, compression can ignite it due to the heat generated sort of like how a diesel engine combusts by super high compression rather than a spark plug. Air molecules got super-compressed and flash ignited.
Yeah this video shows near-vacuum bubbles collapsing and striking a beer bottle. Note that the glass doesn’t break because of a shockwave traveling through the the glass - it breaks because of the tiny bubble collapsing and causing a little bit of water to slam into the glass.
The bubbles are just above 0 atmospheres, while the surrounding liquid is basically just at standard earth air pressure at sea level, around 1 atmosphere. So the difference in pressure here is 1 atmosphere.
The titanic wreck is sitting under 375 atmospheres of pressure and the cabin was at 1.
Know how in a diesel cylinder, the fuel ignites just because of pressure, with no spark plug needed?
