Sulamispisteellään

Sulamispisteellään is a Finnish term that translates to "at its melting point" or "melting". It refers to the temperature at which a solid substance changes into a liquid state. This transition occurs when the substance absorbs enough thermal energy to overcome the intermolecular forces holding its particles in a fixed, rigid structure.

The melting point is a characteristic physical property of a pure crystalline solid and is constant under a given pressure. For example, pure water freezes and melts at 0 degrees Celsius (32 degrees Fahrenheit) at standard atmospheric pressure. Impurities in a substance generally lower its melting point. This phenomenon, known as melting point depression, is a common observation.

The concept of melting point is crucial in various scientific and industrial applications, including chemistry, materials science, and metallurgy. It is used for identifying substances, assessing their purity, and determining their suitability for specific uses, such as in manufacturing or industrial processes. The term "sulamispisteellään" specifically denotes the state of being at this critical temperature, poised to undergo the phase change.
