The air inside the pressure hull has been under one atmophere pressure before the implosion, During the implosion it would undergo instantaneous adiabatic compression until its pressure equals the pressure of water outside. In this case the pressure outside is 400 atmophere..
That’s a compression ratio of 400:1.
To put that into perspective, the people inside rhe Titan submersible were experiencing air being compressed 20 times more than it would be inside the cylinders of a giant running diesel engine in the compression cycle, which also uses adiabatic compression to heat the air/fuel mixture inside the cylinder until it detonated.
Even though the seawater coming in is nearly freezing, The process would have been so quick, that the air instantly heated to tens of thousands of degrees and would completely incinerate their bodies before the heat would have the time to be dissipated by contact with the cold sea water.
That’s if the pressure hull fails completely all at once.
The other possible mode of failure is the pressure hull first fail locally and spring a leak before the failure propagates and the entire pressure hull collapses. In this case a jet of water at 400 atmospheres will squirt in at the first point of failure. Water at that pressure, while not quite enough to cut steel, will instantly cut through any skin, muscle, or bone it encounters along the way.
