The correct answer is: C. specific gravity<\/p>\n
Specific gravity is a dimensionless quantity defined as the ratio of the density of a substance to the density of a standard substance. The standard substance is usually water at a temperature of 4 \u00c2\u00b0C (39.2 \u00c2\u00b0F).<\/p>\n
In this case, the density of the liquid is 850 kg\/m^3. The density of water at 4 \u00c2\u00b0C is 1000 kg\/m^3. Therefore, the specific gravity of the liquid is 0.85.<\/p>\n
Specific weight is the weight of a unit volume of a substance. It is calculated by multiplying the density of a substance by the acceleration due to gravity.<\/p>\n
Specific mass is the mass of a unit volume of a substance. It is calculated by dividing the density of a substance by the acceleration due to gravity.<\/p>\n
Specific density is the density of a substance relative to the density of water at 4 \u00c2\u00b0C. It is calculated by dividing the density of a substance by the density of water at 4 \u00c2\u00b0C.<\/p>\n","protected":false},"excerpt":{"rendered":"
