how much heavier / dencer is water at the bottom of the ocean, with all that pressure on it?

Answer 1

a whole helluva lot

Answer 2

Water is essentially a non-compressable fluid so the density remains the same. The pressure increases with depth because there is a higher column of water, i.e., more force per square area, exerting pressure on you. You could get the same effect by filling a really high (technical term) pipe full of water. For example, if the pipe was 1000' high, the pressure at the bottom would be the same as found at 1000' depth.

Answer 3

water cannot increase in density as it cannot be compacted like air. also, weight just depends upon its mass and the acceleration due to gravity according to newtons 2nd law of motion (weight = mass x gravity) or (w=ma). therefore a glass of water at the top of the ocean and at the bottom of the ocean weights exactly the same and is the same density.

air, however, can be compressed which is why a fixed volume of air will be denser and heavier the deeper you go. (e.g 1 litre of air at 2 bar pressure will expand to 2 litres at 1 bar pressure, hence 1 litre of air at 2 bar pressure is twice as dense and twice the weight compared to 1litre of air at 1 bar pressure)

Answer 4

water cannot be pressureized, thats why it is so hard to breathe/move when yiour down that far, since you can be pressurized, all the water acts on you, causeing a strange reaction ;inside your body, and some times your entire chest may emplode if you go up too fast. p.s. water gains 1 pound of acting pressure (the force on you and me if we went in it) every 3 inches past one foot.

Answer 5

As water is not compressable it will be just as dense and weigh the same no matter how much pressure is applied.

Answer 6

water gains a pound of pressure every inch.

Answer 7

wrong mate, twice as dense but half the volume so the same weight. Doh

Answer 8

it depends how far down you are - doesn't it?
