Sea water will exert more pressure than river water due to its higher density. The pressure exerted by a fluid is directly proportional to its density, so sea water, being more dense than river water, will exert a greater pressure.
Yes, water exerts pressure on the hull of the submarine.
yes
The same reason bricks exert downward pressure. Gravity.
The same reason bricks exert downward pressure. Gravity.
Water is more dense than air is.
The faster the water the more land erosion as the speed of water puts more pressure on the river bank.
Hot water does exert pressure, but the main thing is that it creates steam if hot enough, and that is often used to run machines that require pressure.
When water freezes it increases in volume by %6. That pressure can destroy its' container.
Pure water exerts osmotic pressure as the tendency of a pure solvent will cause osmotic pressure. This is due to the semi-permeability of the membrane which inhibits the movement of water.
Yes.
