Water is most dense at +4 deg centigrade. When it freezes it becomes lighter.
The formula to calculate the density of water for a change in temperature is: Density = Density at reference temperature / [1 - β (T - T_ref)], where β is the volumetric thermal expansion coefficient of water, T is the temperature, and T_ref is the reference temperature.
By cooling it below 4 degrees centigrade whereupon its density will decrease. By heating it above 4 degrees centigrade whereupon its density will decrease. Water is at its densest at about 4 degrees centigrade.
Temperature, salinity, and pressure have significant effects on water density. As temperature increases, water density decreases because warmer water molecules are more spread out. Higher salinity increases water density since dissolved ions make the water heavier. Pressure also impacts density, with deeper water being denser due to the weight of the overlying water column.
To find the density of water at a specific temperature, you can use a reference table or formula that provides the density of water at different temperatures. Alternatively, you can measure the mass and volume of a sample of water at that temperature and use the formula density mass/volume to calculate the density.
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.

no, because the density is denser than salinity.
The density of water changes at different temperatures. As temperature goes up, density goes down.
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.
4° C is the temperature of maximum density for water. Change temperature in either direction from there -- whether you warm it or cool it -- the density decreases.
Only by virtue of the change in density of water. As water expands with temperature rising its density falls slightly so the height of water for a given pressure will increase slightly.
By cooling it below 4 degrees centigrade whereupon its density will decrease. By heating it above 4 degrees centigrade whereupon its density will decrease. Water is at its densest at about 4 degrees centigrade.
The density of water is about 1 g/cm3, and it varies with temperature, not amount. Water is most dense at 4 degrees C. Below that temperature, the density of water decreases, so that frozen (solid) water (ice) is less dense than liquid water. This is why ice floats on water.
As temperature increases, water molecules gain energy and move faster, causing them to spread out and increase in volume, resulting in a decrease in density. Conversely, as temperature decreases, water molecules slow down and come closer together, leading to a decrease in volume and an increase in density.
Most definitely yes. Water has its maximum density at 4° C. By definition this is the point at which clean water has a density of 1 exactly. It gradually becomes less dense as its temperature rises. When it changes state for liquid to gas, it undergoes a tremendous change in density, dropping to 0.0006 at 100° C. When it freezes, it also undergoes a big change in density, but not as drastic. It drops to 0.9150 at 0° C. Since it is less dense than liquid water, ice floats.
Temperature, salinity, and pressure have significant effects on water density. As temperature increases, water density decreases because warmer water molecules are more spread out. Higher salinity increases water density since dissolved ions make the water heavier. Pressure also impacts density, with deeper water being denser due to the weight of the overlying water column.
The density of water does not change based on the amount of salt dissolved in it. The density of pure water at room temperature is approximately 1 g/cm^3.
