Explosive decompression or freezing solid?

If the person was still alive, they would die from suffocation first.

Air would immediately leave the lungs due to the enormous difference in pressure. Oxygen dissolved in the blood would empty into the lungs to try to equalize the pressure, and once the deoxygenated blood arrived at the brain, death would quickly follow.

Blood and other body fluids do boil when their pressure drops below 6.3 kPa (this is called ebullism).

The steam may bloat the body to twice its normal size and slow circulation, but tissues are elastic and porous enough to prevent rupture.

Water vapor would also rapidly evaporate off from exposed areas such as the lungs, cornea of the eye and mouth, cooling the body. Rapid evaporative cooling of the skin will create frost, particularly in the mouth, but this is not a significant hazard. Space may be cold, but it's mostly vacuum and can hardly transfer heat, so the main temperature worry for astronauts in space suits is not how to keep warm but how to get rid of naturally generated body heat.

If the organism was dead, then decompression would likely occur before freezing.

The body is somewhat insulated by the skin and fat layer.

Plus space isn't cold the way liquid nitrogen is - space is an absence of matter so there is in space to sustain or transmit heat. So while something immersed in liquid nitrogen would freeze very quickly, it would take longer in space.

The word “explosive decompression” shows that all of the stress is published roughly directly. If there have been a small gap the scale of a bullet, the group might get an automated alarm sign and check out to make the fix earlier than deadly decompression. With a gap that measurement, it might take a number of mins earlier than low stress might incapacitate the group. If an astronaut blocked the gap along with his frame, the ventilation might be stopped, even though it might be painful (a bullet sized gap might no longer permit him to be sucked out). Water isn't a liquid at 0 stress. If water ice had been warmed in 0 stress it might sublimate, that's difference straight from a great to a gasoline. If there have been entire decompression, the group might die close to immediately. The blood and different fluids of their our bodies might difference to a gasoline instantly. As it does this, the fluids might truthfully be boiling. But the blood temperature has no longer modified, the boiling temperature has. If the group didn't explode, each and every cellphone of their our bodies might nonetheless rupture because the gasoline expands. Death might be quick.

There is very little compressible in the human body to decompress, explosively or otherwise. The main thing is air in the lungs, which, if you allow it to escape to space by exhaling, will do nothing harmful to you. Humans do not explode in space.

Neither will you freeze very quickly. There is a lot of heat in the human body and no way to get rid of it in space except by the slow process of radiation. And that's the side that's not burning up by facing the Sun.

When you are airlocked, you die by asphyxiation, nothing more.

Actually you wouldn't freeze very quickly. The reason you get cold out in the snow is because the cold air is absorbing the heat from your body. Heat is defined as " the random motion of atoms" or better put as " vibration of atoms". In space, even a single atom is few and far between so heat lose due to this is irrelevant. Your body loses small amounts of heat through infrared radiation given off but other than that heat loss is a slow process up until you die of course. Due to the lack of oxygen in space, you can no longer breathe and your body loses energy very fast. But it is only until you die of asphixiation, as someone else put it, then does your body freeze. Small random objects in space not subject to radiation from a star are about 3 degrees warmer than absolute zero. Absolute zero is as cold as you can be before all random motion of atoms stops. Hope this helps.

You would die from the decompression. Your body probably would not explode but the sudden decrease in pressure would cause any gasses in your blood to flash off and you would die of something like a very severe case of the bends. This would happen in you brain as well so I think it would be very fast, maybe only a few seconds.

I don't know how fast you would freeze, but I suspect the others are right in that it could take a good while.

The human body will not explode at all. The skin is durable enough to withstand the vacuum of space.

As to freezing solid, I doubt it. In a robot plane, the computer compartment has to be pressurized to keep it from over heating. I am guessing that is the same for the human body in the vacuum of space. That the body will not freeze right away.

As to the liquid nitrogen, there is matter there to draw heat away. In space, there is nothing to draw it away.

hmmmm

Well I think the effects of a hard vacuum would be more immediate on the body (though I'm not sure if that would be explosive decompression...just collapsed lungs and fluids boiling which likely would kill you instantly if all your cells are disrupted)

It will take a long time for the body to lose all its heat to space. I have no idea how long that would be though (?hours)

I agree with the previous answer. No explosive decompression, no instant freeze.

As was pointed out, space is cold, but it's empty. Vacuum is a wonderful insulator. The best thermos bottles are Dewer flasks with a double wall and vacuum in between.

There is virtually no conductive heat loss with plenty of vacuum around you, and radiative heat loss will be fairly slow.

Neither, see NASA's answer...

Space itself isn't cold, Vacuum is a very good insulator.

The only way to give off heat would be radiation, so freezing would actually take some time (assuming you are far enough from the Sun).
