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.

1 Mercury is a liquid similar to Ant, because powders can lay on its surface and will not sink. 2  However, mercury does so because it is more dense, while ant does so because ant and powder are of the same density. 3  Mercury is the same color in BG-Grey as in the other backgrounds. This makes a mercury thermometer impossible in Powder Game unless clone and wind were involved. 2  In-game mercury does not freeze. 3  This could, however, be possible due to the lowest possible temperature being at about 0Â°C (indicated by ice), while the freezing point of mercury is near -39Â°C.
