Does liquid hydrogen spontaneously combust?

3 things will happen:
H2 will evaporate
water will condense from the air forming ice crystals
the floor will get very cold & probably crack
no spontaneous combustion.

Let's say the floor is wood. The liquid Hydrogen would cause the floor to become so brittle that it would shatter like glass if hit with a hammer.
The liquid Hydrogen, of course, would boil away. It wouldn't spontaneously combust with the floor but if enough hydrogen mixed with the oxygen in the room, and you had a spark, you could have an explosion.
Liquid Hydrogen has one of the lowest boiling points of any liquid.

It depends on how high you were to pour it from, mostly the hydrogen would change state into a gas and become harmless. Very near the floor and it would 'freeze' the material that the floor is made of.

Usually, when an object is dispersed into liquid nitrogen, that object would become frozen. But in this case, the situation is rather the opposite.
When liquid nitrogen is poured onto a solid floor, the floor WILL NOT become frozen. Liquid nitrogen when compressed, remains at a liquid state, but when poured onto the floor, it will convert to a gaseous state.
As a solid floor will be too dense to become consumed (frozen), the, the liquid nitrogen will also convert to a solid state as it hits the solid floor; thus leaving frozen ice as the remains.

It won't explode, but will freeze the floor as it turns back into gas. (You don't want to be in the same room when you do this.)
Hydrogen will mix with Oxygen and explode only if there is a spark or flame introduced.

it would change state to a gas?
i don't think it spontaneously combusts but i could be wrong. i suppose it might as it just needs to mix with oxygen but I'm not sure :)

I wouldn't be smoking at the time. you may also need an oxygen supply to breath.

You would bugger the flooring, that's for sure !
