Read MoreOct 20, 2014· So, why do the temperature and density change so dramatically in the vertical direction? It's because of gravity. We have both an upward and a downward force on the cube. The downward forces come from molecules hitting the top of the cube---pressure---and gravity.

Read MoreRelative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). The term "relative density" is often preferred in ...
