Kjølefase
Kjølefase, also known as the freezing phase, is a physical process in which a liquid transforms into a solid state due to a decrease in temperature. This phase transition occurs at the freezing point, which is the temperature at which the vapor pressure of the liquid equals the vapor pressure of the solid. During the kjølefase, the liquid's molecules lose kinetic energy, causing them to slow down and arrange themselves into a fixed, ordered structure characteristic of the solid phase. The heat released during this process is known as the latent heat of fusion. The kjølefase is a fundamental concept in thermodynamics and plays a crucial role in various natural phenomena and industrial processes, such as the formation of ice, the freezing of water in pipes, and the production of ice cream.
