jäämuodossa

Jäämuodossa refers to a state of being frozen or solid, typically describing water that has transitioned into ice. This phase change occurs when the temperature of water drops below its freezing point, which is 0 degrees Celsius (32 degrees Fahrenheit) at standard atmospheric pressure. The transformation involves water molecules slowing down and arranging themselves into a crystalline lattice structure.

This solid form of water is known for its rigidity and is a common occurrence in natural environments, forming features like glaciers, ice sheets, and frost. The density of ice is lower than that of liquid water, causing it to float, a property crucial for aquatic life in colder climates. Jäämuodossa can also be observed in everyday life, such as in ice cubes used for cooling beverages or in frozen food products. The process of thawing reverses this state, returning the substance to its liquid form as it absorbs heat and its molecules gain kinetic energy.
