Hoppa till Air density and volume – Humidity depends on water vaporization and condensation. Humid air is less dense than dry air because a molecule . Relative_humidityCachadLiknandeÖversätt den här sidanRelative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor.

If the relative humidity is 1percent at the same air temperature, then it feels like °C (°F). In other words, if the air is °C (°F) and . The relative humidity in air can be expressed by partial vapor and air pressure – density of the vapor and air – or by the actual mass of the vapor and air. Density of dry air and water vapor – moist or humid air.

Pressure, temperature and volume for an ideal or perfect gas like air with water vapor – or moist air. The assumption that humid air is heavier than dry air is wrong. Humid air can be modeled as a mixture of air and water vapor.

In the simplest analysis, water and air are treated as ideal gases but in principle there is . To understand humidity, you first have to realize that there’s water in the air all around you.
