+100 °Bé (specific gravity, 3.325) would be among the densest fluids known (except some liquid metals), such as diiodomethane. Near 0 °Bé would be approximately the density of water. −100 °Bé (specific gravity, 0.615) would be among the lightest fluids known, such as liquid butane .
Lithophile heavy metals are mainly f-block elements and the more reactive of the d-block elements. They have a strong affinity for oxygen and mostly exist as relatively low density silicate minerals. [102] Chalcophile heavy metals are mainly the less reactive d-block elements, and period 4–6 p-block metals and metalloids.

“The easiest way to lower the amount of heavy metals in a food is to water it down,” Bowen said. “If water is the first ingredient on that baby food’s ingredient list, beware. Water doesn ...

True specific gravity of a liquid can be expressed mathematically as: =, where is the density of the sample and is the density of water. The apparent specific gravity is simply the ratio of the weights of equal volumes of sample and water in air: =,,, where , represents the weight of the sample measured in air and , the weight of an equal ...
