The composition of air can be considered to be composed of three parts, namely, absolute air, water vapor and layer angstroms. Absolute humidity is the mass of water vapor contained in air at a certain pressure and temperature. Saturation humidity is the maximum mass of water vapor that air can contain under such conditions. The higher the temperature, the more water vapor can be contained in the air, and the greater the saturation humidity. The ratio of absolute humidity to saturation humidity is the relative humidity. If the humidity of the air is maintained to lower the air temperature, when the temperature is lower to a certain value, the partial pressure of the water vapor reaches the saturation pressure corresponding to the current air temperature, and the water vapor in the air under the condition reaches saturation. If the air temperature is reduced even further, water vapor condenses out of the air to form "dew droplets". This phenomenon is called "condensation".
