how does temperature affect water movement?

Answer 1

Water movement, whether it is in a glass of drinking water, in a lake, or in the ocean is mainly controlled by density. We've all seen how oil floats on the top of water. This is due to oil being less dense than water (there are fewer particles in a given volume). Well, one factor that determines the density of water is its temperature. The warmer the water gets, the farther apart the molecules become, and the less dense it becomes. If there is cold water that is more dense than the warm water, the cold water will sink and flow beneath the warmer water (you can see this happening in a glass as ice melts). Water has an interesting property though. Once the temperature gets very close to the freezing poing, around 4 degrees celcius, it actually begins to expand again and becomes less dense than the liquid. This is why ice floats instead of sinks. This property is why lakes and streams don't freeze solid and allow the fish to survive under the ice.
The sinking of cold water at the poles of the oceans is what drives the deep ocean currents that affect everything from climate to primary productivity in the ocean.

Answer 2

i can not answer the fabric question. i'm no scientist, yet so some distance as i'm conscious, water will become vapour because it gets warmer and to ice because it gets chillier. With this in suggestions, i might assume, an merchandise is far less streamlined in chillier water via fact water is closer to being a stable the chillier it gets for this reason greater resistance via one in all those friction. i'm going to have a flow on the climate one certainly. All could be streamlined. It relies upon on how they make the fabric. think of of nylon shirts as against nylon american soccer.

Answer 3

Warm water will rise above cold water. This causes a water flow within a system. Warm water wants to rise, cold water wants to sink. A good way to illustrate this is to put food coloring in water and make ice cubes with it. Use a clear container and put the died cubes into warm water. Watch how the cold water acts.

Answer 4

As water temperature increases, its viscosity decreases. This is because as it gets warmer, it expands, reducing its density.

Answer 5

it speeds up the molocules of the water and makes the water hotter to the point that it can boil

Answer 6

when it gets hot it moves when it gets real cold it freezes and stops
