Relative humidity. Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. It requires less water vapor to attain high relative humidity at low temperatures; more water vapour is required to attain high relative humidity in warm or hot air.

Elemental mercury is a heavy, silver-white liquid metal that can be found at trace levels in many minerals with greater concentrations in fossil fuels. There are three forms of mercury in the environment: elemental, inorganic, and organic mercury.All forms of mercury are toxic.www.epa.state.oh.us/opp/ pq/fall98/merc498.html. Elemental mercury occurs naturally in three valence states: elemental (Hg0), monovalent-mercurous (Hg1+), and the divalent mercuric (Hg2+).Elemental mercury is the most stable form and is only slightly water-soluble.here are three forms of mercury in the environment: elemental, inorganic, and organic mercury.
