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.

The planet Mercury is the color grey, simply because this planet has little to no atmosphere, therefore we just see the rocky surface.ercury is the Roman name for the Greek god Hermes, who is the messenger of the Gods.
