ogleme said:Oh great and wise Mayday, does hot water weigh more than cold? (Given that they are the same amount and in the same kind of container, etc. etc.)
O.K. this is a doozy that stems from a conversation with my husband. He remarked that our Earth and universe couldn't function properly without the property of ice being able to float in water. It has something to do with our weather because hot water rises and cold sinks. But I had to ask what about outer space when there is no planetary gravity? Can ice float in outer space?
So here's the question:
Imagine an airtight container of water (with some air inside) with one ice cube is in zero gravity (taking into account expansion etc.). There is no movement, no temperature changes.. Would the cube float in the water near the air or would it just stay in place wherever it was in the first place. What if you did shake it first and then place it in zero gravity, would the water and air mix slowly over time like a lava lamp with the ice cube in the center? Would the movement of the water and air create enough friction to melt the ice ever so slowly?
Also, if you're bored,
