Küllastun

Küllastun is an Estonian word that translates to "saturated" in English. This term has various applications across different fields, most commonly in chemistry and physics, but also in everyday language.

In chemistry, saturation refers to a state where a solution can no longer dissolve any more solute. This can be either a liquid solution or a gas. For example, if you add sugar to water and stir, the sugar dissolves. However, at a certain point, no more sugar will dissolve, and the solution is said to be saturated. The temperature and pressure significantly influence the saturation point. In the context of gases, saturation refers to the maximum amount of a vapor that a gas can hold at a given temperature and pressure. For instance, humid air is air that is saturated with water vapor.

In physics, saturation can describe a point where a material's response reaches its maximum capacity or limit. This is often seen in magnetism, where a ferromagnetic material becomes saturated when all its magnetic domains are aligned, and further increases in the external magnetic field do not result in a stronger magnetic effect. In electronics, a transistor is said to be saturated when it is conducting its maximum possible current, acting like a closed switch.

In everyday language, "küllastun" can be used to describe feeling full after eating a large meal, implying a state of being completely satisfied and unable to consume more. It can also refer to something being filled to capacity or overflowing.
