Atmospheric humidity

Saturated vapor I

---

Liquid water can evaporate and turn into water vapor. Conversely, water vapor in the air can turn into the water again. The “saturation state” is the state in which air contains the maximum amount of water vapor. As the temperature rises, the amount of saturation vapor increases.

Psychrometer - hygrometer

---

A psychrometer is a simple device that allows you to determine the humidity by measuring the difference in how much water evaporates. The wet-bulb hygrometer consists of two thermometers, a dry-bulb, and a wet-bulb. Humidity is measured using the temperature difference between the two thermometers.

Diffusion of two gases
