The density varies with temperature, but not linearly: as the temperature increases, the density rises to a peak at 3.98 °C (39.16 °F) and then decreases; the initial increase is unusual because most liquids undergo thermal expansion so that the density only decreases as a function of temperature.

WebThe α form of the tetrahydrate has density 1.33 g/cm 3. It melts congruously at 7.55 °C into a liquid with 35.7% NaOH and density 1.392 g/cm 3, and therefore floats on it like ice on water. However, at about 4.9 °C it may instead melt incongruously into a mixture of solid NaOH·3.5H2O and a liquid solution. [17] Webdensity, mass of a unit volume of a material substance. The formula for density is d = M / V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth ’s density is 5.51 grams per cubic centimetre.
