Definition It is the proportion of mass to volume. It is the relative proportion of the Density of the sample to the Density of the reference. Calculation To calculate the Density of any material weight and volume of the substance must be known. To calculate the specific gravity, the Density...
Relative density and specific gravity are interchangeable terms that refer to the density of a gas relative to air at some defined pressrue and temperature.Relatie density is a useful value in that it defines gas composition independent fo pressure and temperature.aThe opnly variable tha tcna ...
Specific gravity, more formally known as relative density, is a measure of thedensityof a substance in comparison to the density of water. Forsolidsandliquids, specific gravity is generally measured in relation to water at its densest state (at temperatures of 4 Celsius or 39.2 Fahrenheit), and...
It is common to use the density of water at 4oC (39oF) as a reference since water at this point has its highest density of1000 kg/m3or1.940 slugs/ft3. Since Specific Gravity - SG - is dimensionless, it has the same value in the SI system and the imperial English system (BG). SG...

比重gravity密度笔记densitynotes Honors Chemistry I Density & Specific Gravity Density is one of matter’s intensive properties. An intensive property is a property of the substance that is independent of the amount of the substance. Color, luster, malleability, and ductility are some other examples...
). By original definition, 1 ml of pure water has a mass of very, very close to 1 g, so close that the density of water is almost always simply rounded to "exactly" 1 for everyday purposes; this makes g/ml a particularly handy unit, and it comes into play in specific gravity....
Both density and specific gravity describe mass and may be used to compare different substances. They are not, however, identical measures. Specific gravity is an expression of density in relation to the density of a standard or reference (usually water). Also, density is expressed in units (...
