jäätuvust

Jäätuvust refers to the process and phenomenon of freezing. It describes the transformation of a liquid into a solid state, typically due to a decrease in temperature. This change occurs at a specific temperature known as the freezing point, which is characteristic of the substance undergoing the transition. For water, this freezing point is 0 degrees Celsius or 32 degrees Fahrenheit.

During freezing, the molecules within the liquid lose kinetic energy and their movement slows down. As they cool, they arrange themselves into a more ordered, crystalline structure, forming the solid phase. This molecular rearrangement releases latent heat, a phenomenon that can cause the temperature to remain constant at the freezing point until the entire substance has solidified.

Jäätuvust is a fundamental physical process with significant implications in various fields. In meteorology, it is responsible for the formation of ice, snow, and frost, influencing weather patterns and climate. In materials science, understanding freezing is crucial for processes like cryopreservation, food storage, and the development of antifreeze agents. Geologically, it plays a role in permafrost formation and the erosion of rocks. The rate and manner of freezing can affect the resulting solid's properties, such as its density and crystal structure.
