Definition of 'appraise'. appraise. If you appraise something or someone, you consider them carefully and form an opinion about them. This prompted many employers to appraise their selection and recruitment policies. Gloria slid an appraising eye over the rest of the rack before reaching for the dress.
Because the density is directly related to the mass, the specific gravity can also be determined from the ratios of the mass of the object to the mass of water, or the weight of the object to the weight of water. The specific gravity has no units and its value determines if the object will float or sink in water.esson Summary. The specific gravity of an object is the ratio between the density of an object to a reference object. Usually, our reference object is water, which has a density of 1 g/mL or 1 g/cm^3.
In physics, a substanceâs specific gravity is the ratio of that substanceâs density to the density of water at 4 degrees Celsius. Because the density of water at 4 degrees Celsius is 1,000 kg/m3, that ratio is easy to find. For example, the density of gold is 19,300 kg/m3, so its specific gravity is the [â¦]
