The term is correctly specific gravity (also relative density) which compares the density (typically in g/cm3) to that of water (which is practically 1 g/cm3).
Relative density, is also called specific gravity, and it is the ratio of the density (mass/volume) of a substance to the density of a particular reference substance, usually water. So, where density has the units of mass/volume, relative density (specific gravity) is unitless.
The relative density of a substance X, relative to a substance Y isDensity of X/Density of Y= (Mass of X/Volume of X) / (Mass of Y/Volume of Y)If Y is water then the relative density is called the specific gravity.
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.
Density is a derived unit: mass divided by volume.
To find the relative density of a substance, you divide the density of the substance by the density of water at a certain temperature. Relative density is also known as specific gravity and is a unitless value used to compare the density of a substance to that of water.
It is called relative density. If the second substance is pure water (at normal temperature and pressure) then the ratio is the specific gravity.
The number that compares an object's density to the density of water is called specific gravity. It is a unitless quantity representing the ratio of the density of a substance to the density of water.
Specific gravity is measured by comparing the density of a substance to the density of a reference substance (usually water). It is typically determined using a hydrometer or a densitometer. The specific gravity of a substance is a unitless value that indicates how much denser or lighter the substance is compared to water.
No that is incorrect. When the density of an object is compared to the density of water it is called the Relative Density and no units are specified, since the value obtained is a ratio. Specific Density is expressed in units such as Kilograms per cubic metre or grams per cubic centimetre and does not refer to the density of water. It is worth noting however that the density of water at normal temperatures is very close to 1000 Kilograms per cubic metre, or 1 gram per cubic centimetre, so the numeric values of Relative Density and Specific Density are very nearly the same.
This is called the Specific Gravity of a substance. The density of the material divided by the density of water yields the specific gravity, a specific gravity greater than 1 indicates the substance will sink in water. A specific gravity less than 1 indicates the substance will float in water. Because the units expressed in density cancel each other out specific gravity has no unit dimensions. example: substance 1 has a density of 12 grams per ml water has a density of 1 g/ml then substance 1 has a specific gravity of 12. 12 g/ml / 1 g/ml = 12 *note: for true specific gravity the atmospheric pressure, absolute , and the temperature absolute of both the sample material and the water must be indicated in the calculations as well. ** for gasses the constant or reference medium is air
Density. Since density = mass/volume, if you have a substance A, it has density(A), which is given in a standard form of ## grams per cm^3 (cubic centimeter) or mL (milliliter). The density of water is 1.0g/mL. Thus, suppose the mass of substance A is 10 grams and it's volume is 5 cm^3. Then, it's density is 2g/mL. If you looked at 5cm^3 (or 5mL) of water, it's mass would be 5 grams. Therefore, the ratio of the two masses of equal volumes substance A and water is exactly the ratio of the two densities, which equals the density of substance A.
A hydrometer is a device used to measure the specific gravity or relative density of liquids. In Hindi, a hydrometer is called "हाइड्रोमीटर" (pronounced as "haideromeetar").
