Calcium carbonate (Caltrate 600, Os-Cal 500, Tums Extra, Tums Chewy Delight, and Many Other Brands and Generics) is a prescription drug used as part of a regimen to prevent and treat osteoporosis in individuals with low levels of calcium in their diets and as

Phase Diagrams | Chemistry - Lumen Learning

A phase diagram coines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indie the physical states that exist under specific conditions of pressure and temperature, and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points).
