yeah.....it does change when you add some liquid to it......
No, it would only have a density of 1g/cm3 if it was pure water, at 4oC and at 760 mm Hg pressure (absolute)
it depends what kind of water. if it is pure then it is the same density. if not if difers
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
Density = mass / volume. So if the volume changes, the density will obviously also change.
If you poor out some of the water in a bucket does the density of water change?
No.
No.
no
The water will be calm, because a change in density causes water to move and can also cause deep water currents
yes. the density of a element will not change only the mass and volume will.
the density of sea increases with depth
Salt
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.
