No.
If the density of surface water in a lake does not change, then the water at the surface will maintain its relative position compared to the denser water beneath it. This will result in stable stratification, with the surface water layer remaining on top and the denser water layer staying below.
A rock's density remains the same when submerged under water because its mass and volume do not change in the water. Density is calculated by dividing an object's mass by its volume, and since both the mass and volume of the rock remain constant underwater, its density also stays the same.
No, the density of a material does not change when it expands. Density is a measure of how much mass is contained in a given volume, so even if the material expands and takes up more space, the total mass remains the same, resulting in no change in density.
If you mean why does the density of an object not change when it undergoes a physical change such as a change of shape then the answer is because density is a chemical trait found by dividing the mass by the volume and if you modify the volume then the mass will also be modified for example water has a density of 1 g/cm^3 meaning if you have 3 grams of water it takes up 3 cm^3 even if you change the mass when you change the mass you are also changing the volume same goes if you change the volume you change the mass. In other words mass and volume are relative to each other and when you divide mass by volume you get a number the density the density represents a ratio for water the density is 1 g/cm^3 the ratio of mass to volume is 1:1,1/1, or 1 to 1 meaning for every cm^3 you have of water you will have an equivalent amount of grams. 1 to 1 1 part mass 1 part volume but that is just for water every substance has a density and they rarely if ever are equal.
Density is mass per unit volume of a substance. The Mass and volume of water is in the ratio of 1:1 .There fore the density of water is 1. With rise and decrease of temperature the volume increases or decreases to change the water density.
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.
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.
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.
A change in density may accompany a Physical change. When liquid water becomes solid water, the solid water FLOATS; (is less dense) on top of its liquid form.Density itself is a physical property, not a change.
