Yes, and proud of it too!Bandersnatch said:So, we're the 'physics nerd forum'?
Suppose that you have an arbitrarily shaped blob of water. Does the volume of that blob decrease if you mold it into a sphere shape? If not, why would you expect atmospheric pressure to do anything to alter the shape?Chuck Keranen said:So as I understand it, the atmospheric pressure surrounding a quantity of water will give it its globe shape.
Water vaporChuck Keranen said:Becoming what? Water vapor, or splitting into hydrogen and oxygen?
Vapor. The molecules are held together by pressure, the atoms making the molecules are bound together and will not just drift apart.Chuck Keranen said:Becoming what? Water vapor, or splitting into hydrogen and oxygen?

Yes, the water pressure in zero gravity will decrease due to the absence of gravity pulling down on the water. In a zero gravity environment, the water molecules will spread out evenly and there will be no force pushing down on the water, resulting in decreased pressure.
Water in zero gravity will form into a spherical shape due to surface tension. This is because the water molecules are attracted to each other, creating a cohesive force that pulls them together into a compact shape.
Yes, astronauts can drink water in space. However, the water must be specially packaged in a sealed container to prevent it from floating away in the zero gravity environment. It is also important for the astronauts to be careful when drinking to avoid any spills or leaks.
Water pressure in space is measured using devices called manometers. These instruments use the height difference between two water columns to measure the pressure of the water. However, in zero gravity, other methods of measuring pressure, such as pressure sensors, may be used.
Yes, water can freeze in zero gravity. However, the freezing process may be different due to the absence of convection, which is the movement of heat through a fluid caused by differences in density. This can result in a slower freezing process or the formation of different ice crystal structures.
