yeah.....it does change when you add some liquid to it......
Water increases in density until 4 degrees Celcius, when its density starts to decrease again due to hydrogen bonding. (see Wikipedia.org for more.) As water moves away from the equator, it gives off heat. As it cools, its density increases.
It's actually pretty easy. If the density of the substance is higher than the density of water, the object will sink. If the density of the substance is lower than the density of water, the object will float. Be aware though that various substances may have dissolved into the water, thus changing its density. For example, seawater has a different density than fresh water.
It won't change. Density is volume divided by mass, so if volume doesn't change, density doesn't change unless you change the mass of the object.
The best way would be to change the state of the water. In other words, have ice floating in liquid water, while steam is above that.
yes water can increase the density of water as wood has the power to absorb water and so the density of water is drastically increased
No, your density does not change when you are in water. Your density is determined by your mass and volume, and it remains constant regardless of the medium you are in.
No.
To calculate the water difference when the density changes, you would need to account for the change in volume due to the density change. Use the formula: Difference in water volume = Original water volume / Original water density - Original water volume / New water density. Multiply this difference in volume by the new water density to obtain the actual water difference.
No, pouring out some water from a bucket does not change the density of the water remaining in the bucket. Density is a physical property of a substance that remains constant regardless of the amount of that substance present.
Density = mass / volume. So if the volume changes, the density will obviously also change.
no
yes. the density of a element will not change only the mass and volume will.
The only way to change the mass of water would be to either add more of it (which wouldn't change it's density - density is an intensive property, not extensive) or to change the isotopes of hydrogen and oxygen in the water - thus getting "heavy water" such as is present as an intermediate materiel in the refining of tritium and as a moderator in some nuclear reactors.

Otters can change their density to either float on the surface of the water, or sink. Therefore, their density can vary.
The density of water does not change when the volume changes. This is because density is a proportion of weight to volume. The density of water changes with temperature, but is approximately 1g/ml.
Yes, the density of vapors is lower than the density of the liquid.
