I have a question about how liquid water behaves in space. You cant have liquid water in space is probably your retort but here is the question that i thought about after a strange dream. Sorry to interupt the more serious astronomy questions on this board.
Lets say that a body of water with a diameter of 100m and a temperature of 37 degrees celcius somehow leaks out of a huge space station. this ball is perfectly spherical and in the center of the body a diver with scuba gear is located.
First, how long will it take for the temperature of the water to reach 7 degrees celcuis?
How will the ball of water behave? since there is no atmospheric pressure in space, how will the surface of the body react to that?, will it turn to gas or freeze?
How long will the scubadiver survive in the center of this body of water? Give me a guestimate, what will kill him?, my guess is suffucation or if he has enough oxygen hypothermia from the water getting to cold.
EDIT: Ok, the diver will obviously die from the lack of atmospheric pressure and not from suffucation or cold, silly me.
