Water in a glass

If you drop a glass of water straight down at a high speed, will the water stay in the glass or what will happen with it?

the water will evaporate
2021-09-19 22:50
in a vacum it would stay in the cup, but the fact that it is falling through air might change that. we need a fluid dynamics person here!

The water will become steam and evaporate

At what speed does it become steam?

at around 100°C

Yes obviously but do you really reach that temperature while falling through the air?
2021-09-19 23:02
LOL So are we now making assumptions about air pressure?

due to inaction water will not maintain glass' speed if the gap of the glass is pointing upwards when you throw it. So it will get out if it can

+1, depending on the height

He isn't throwing he is dropping the glass, which must mean releasing it from a grip so really the only significant forces acting on the water and the glass is gravity and aerodynamic drag - that is providing the dropping of the glass is done in such a manner no rotation or change in orientation is introduced and of course it is done at a location where there is no movement in the air it is traveling through. Thus - the water will stay in the glass unless the fall is so long the glass reaches a speed where the aerodynamic drag creates a negative pressure creating essentially a suction effect on the water which then could be disturbed and some may escape the glass.

its actually hard to explaing such stuff with text only

Agree. The description of the OP also leaves out lots of details so to give an answer all sorts of assumptions must be made. Like are we talking a theoretical drop from infinite height or 1 meter or... to name just one.

The glass will hit the ground first

why water in glass and not glass outside water
