No.At high altitudes you are further away from the centre of the earth and so the force of gravity is weaker - or smaller, Consequently, it will weigh less.
However, given that the radius of the earth is 6371 kilometres, even at the top of Mt Everest, the difference would be less than 0.15%.
No. Neither your, mine or anybody else's attitude can change anything about water.
But, if you mean altitude, then yes, as the atmospheric pressure reduces as you go higher, the density of water does change slightly with altitude.
I presume you mean the same volume of water. No, it would weigh less. If you are further from the centre of the Earth, the pull of its gravity is reduced.
The density of air decreases as altitude increases.
I am assuming that you mean mass of an object. The answer is no, it does not change. Mass (Density) stays the same wherever the object is, only its weight will change if the force of gravity is different.
Altitude has a large affect on the air pressure and air density. Air density reduces with altitude and air pressure reduces with altitude as well.
If you poor out some of the water in a bucket does the density of water change?
At standard temperature.
The density of air decreases when the altitude rises.
density changes as the altitude changes.
The density of air decreases as altitude increases.
The density of the atmosphere decreases with altitude.
Density Altitude is the altitude relative to the standard atmosphere conditions (ISA) at which the air density will be equal to the indicated at the place of observation.
As the altitude increases, the density of oxygen decreases.

The density of air decreases with increasing altitude.
Density = mass / volume. So if the volume changes, the density will obviously also change.

"Density altitude is the altitude in the International Standard Atmosphere at which the air density would be equal to the actual air density at the place ofobservation". See the related link.Atmospheric density corresponds to the distance from earth's gravitationalcenter, whereas altitude refers to the vertical distance from a set point on earth's surface.Worth noting is the fact that temperature and humidity are factors in air density, and must be adjusted for to give an accurate density altitude.
