What does density of water mean?
The density of anything is the ratio of the weight (really the mass) to the volume that the material occupies. Water was involved in the original definition of units of mass and volume, so it has a rather special value of density. To a good approximation, the density of water is 1 gram per milliliter.
Why is density needed to know whether a substance will float or sink in water?
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.
Does water affect density of wood?
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
If the volume is 20ml its mass will be 20 grams why?
this is valid for water only (or any fluid with same density as water) water density (@0°C) = 1000 kg/m^3 (actual value is 999.8395 kg/m^3) = 1 g/ml volume = mass / density = (20 g) / (1 g/ml) = 20 ml
Why do you use water to determine specific gravity?
Water was used as the standard because at first, the cubic centimetre was defined so that pure water, at 4 deg C and a pressure of 1 bar, had a density of 1 gram per cubic centimetre. The specific gravity of other substances, being the ratio of their density to that of water, meant that their specific gravity would have the same numeric value as their density. However, an error in defining the centimetre resulted in a change in its definition and the density of water is no longer 1 g/cm3.
What does mean that plasticine has higher density value that water?
means that plasticine has higher density.
Why is the temperature of water shown when the value of its density is given?
The temperature of water is shown when its density is provided because water's density is temperature-dependent. As temperature changes, the kinetic energy of water molecules affects how closely they pack together, altering its density. Therefore, specifying the temperature ensures that the density value is accurate and relevant for calculations or comparisons, as the density of water at 4°C, for instance, is different from that at 20°C or 100°C.
What does density tell you about salt water?
The density of a salt water solution compared against the densities of "pure" water and salt provides an approximate value of the ratio of water to salt in the mixture.
What is the term for the ratio of an object's density to that of water?
The term for the ratio of an object's density to that of water is specific gravity. It is a unitless value that helps determine whether an object will sink or float in water based on its density relative to water.
When comparing the density of a solid or a liquid to the density of water what is the ratio called?
Some folks in the lab call it "spee gee" which is slang for specific gravity (SG). It's relative density, the density of liquid - or any given substance - to the density of water. Surf the link. The formula for density is D= Mass/Volume.
What does density of water mean?
The density of anything is the ratio of the weight (really the mass) to the volume that the material occupies.

What is the density of di water at 22.9 degree Celsius?
it is 0.997561, internationally excepted value
What is the density of water with 50 grams of salt in it?
The density of water with 50 grams of salt in it will be slightly higher than the density of pure water. The exact value will depend on the amount of water used, but in general, adding salt to water increases its density due to the presence of the dissolved salt molecules.
How much density does water contain rose?
Water has a density of approximately 1 gram per cubic centimeter (g/cm³) at 4 degrees Celsius. This density can vary slightly with temperature and pressure, but it remains close to this value under standard conditions. The density of water is what allows objects, like a rose, to float or sink depending on their own density relative to water.
If you had a bathtub full of water would the density of all of the fluid in the tub be the same as only 1 gram of the liquid?
No, the density of a bathtub full of water would not be the same as just 1 gram of water. The density of water is a constant value regardless of the amount of water present. Density is defined as mass per unit volume, so 1 gram of water would have the same density as any volume of water.
Experimentally what is the averange density of water?
The density of water is 1.0 g/ml2In word form it is one gram per milliliter cubed
What is the comparison of density to density of an equal volume of water?
If the density of a substance is greater than the density of water, it will sink in water. If the density of a substance is less than the density of water, it will float on water.
