How is called the density of any substance compared to the density of water?

Water's density is 1.
If an object floats, it's density is less than 1.
If an object sinks, it's density is greater than 1.
Specific Gravity can be calculated as:
(weight in air) / ((weight in air) - (weight in water))

∙ 6y agoMost substances become more dense when they solidify, because the same amount of particles are taking up a smaller amount of space, but ice is actually less dense than water, and so it floats on water.
---
Water's solid form is less dense than its liquid form, while the opposite is true of most other substances.
---
Substances that change phase from liquid to solid when cooled have lower molecular pressure, and are typically denser as solids than as liquids. Water also loses molecular energy as it turns into ice, but the presence of hydrogen bonds forms a solid lattice that takes up MORE space than the water molecules did --- so ice is less dense.

∙ 13y agoThe density of substances are compared to water frequently because water at room temperature has a density of about 1g/ml, or 1 gram per milliliter. Since it has a density close to a whole number, it makes it easier to compare other materials to it. I hope that answered your question.

∙ 9y agoMost substances are more dense in solid form than in liquid form. Water is an exception. Ice is less dense than water, which is why ice cubes float.
Wiki User
∙ 12y agoThe density of water is 1. That's different. Everything else is higher or lower.
Wiki User
∙ 15y agoThe density of a substance is compared to the density of water so that we would know if the substance is less dense or if it is denser.
Wiki User
∙ 15y agobecause water is the easiest thing to compare to, with only 1 g/cc.
Wiki User
∙ 12y agoThe density of different substances are always compared to the density of water because water is considered a neutral substance since it has a density of 1g/ml.

What defines the ratio of the density of a substance compared to the density of water at 4 celsius?
specific gravity
The density of water is equal to 10 gcm3 A substance with density equal to 09 gcm3 would in water?
float
If 1 liter of substance weighed 1 kilogram what would the substance be?
A substance with approximately the same density as water.
Does the same volume of all dry substances weigh the same?
No. The weight of a given volume of a solid is dependent on its DENSITY (weight per volume). The value provided may be its absolute density (at a given temperature) or its specific gravity(density compared to another substance, usually water).
The density of water is equal to 1.0 A substance with density equal to would in water?
It depends on the units you are using for density.Typically, water is thought to have a density of "1" at 4 degrees Celcius. But that is assuming you are using (g/cm3) as your units.Density of water is dependent upon other factors such as impurities in the water as well.
What is the relationship between the density of a substance and its specific gravity?
Specific gravity is the density of a substance, compared to (divided by) the density of a reference substance, usually water.
What defines the ratio of the density of a substance compared to the density of water at 4 celsius?
specific gravity
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 speciffic gravity mean?
Specific gravity is defined as the density of a substance, compared to the density of water. This is roughly equivalent to the density, expressed in kilograms/liter.
Is specific gravity the same as density?
More or less. Specific gravity is the density of a substance, compared to the density of water - so the units may vary.
What is the number that compares an object's density to the density of water called?
That is the specific gravity of the substance.
What is meant by relative density of a substance?
The relative density of a substance is defined as the ratio of density of any substance to the density of water at 4 degree celcius.Formula=Density of any substance/Density of water at 4 degree celcius.
What is the ratio of density?
Density is a derived unit: mass divided by volume.
What can you infer about the density of a substance if a block of that substance floats in water?
because the density is lower than water.
What can you infer about the density of substance if a block of that substance floats in water?
because the density is lower than water.
What is density compared to?
Density = mass / volumeThe density of an object affects how it will float in another. Example the density of hydrogen is ~ 0.08 g / L whereas the density of air is ~ 1.2 g/L. Therefore, hydrogen floats in air.For an object to float in water it has to have a density less than 1.0 g/mL or 1.0kg/L.densities can be compared to see if an object will float.densities of pure substance can be checked with reference books or online. If a substance is impure then its density will not be the same as the reference value. Densities can be compared to check if the substance is pure. When Indiana Jones replaced a block of gold with an equal volume of water to avoid a trap springing would not have worked. Why? Density of gold is 19.3 times heavier than an equal volume of water.
What the formula for relative density?
The relative density of a substance is the ratio of its density to the density of some standard substance. The standard substance for solids and liquids is water. Thus for solids or liquids: Relative density = denisty of substance (kg/m3) / density of water (kg/m3) Relative density therefore has no units, it is a number, and indicates only how many times more dense the substance is than water. The relative density of water is 1 or 1000 kg/m3.
