Examples of specific gravities of common liquids at 25 degrees Fahrenheit include 1.052 for acetic acid or vinegar, 0.826 for ammonia, 1.100 for ethylene glycol, 0.871 for turpentine, and 1.028 for sea water. All the specific gravities stated above are in relation to the density of water of 4 degrees Celsius or 39.2 degrees Fahrenheit, which has a specific gravity of 1.000.Continue Reading
Other examples of specific gravities for common liquids include 0.703 for olive oil at 15 degrees Fahrenheit, 0.820 for kerosene at 60 degrees Fahrenheit, 0.701 for octane at 25 degrees Fahrenheit, 1.035 for milk, and 0.739 for the gasoline used in vehicles at 60 degrees Fahrenheit.
Specific gravity of an object is calculated by dividing its density by the density of a reference material. When liquid is involved, the reference material is usually that of pure water at 4 degrees Celsius. Due to the fact that specific gravity depicts a ratio, it is a unitless quantity.
Density is calculated by dividing the mass of an object by its volume, and it is related to how tightly packed the atoms of an object are. Density of a material varies with temperature. Materials with smaller densities, and subsequently smaller specific gravities, float on top when mixed with a material of greater density. An example is oil, which has a lower density and specific gravity than water, floating on top of water when mixed.Learn more about Motion & Mechanics
