bræðsluhitastig

Bræðsluhitastig is the Icelandic term for melting point. It refers to the specific temperature at which a solid substance transitions into a liquid state under standard atmospheric pressure. This transition is a physical change, meaning the chemical composition of the substance remains the same, only its physical form alters.

Different substances have unique bræðsluhitastig. For instance, pure water melts at 0 degrees Celsius (32 degrees Fahrenheit), while iron has a much higher bræðsluhitastig of approximately 1538 degrees Celsius (2800 degrees Fahrenheit). Impurities in a substance can often lower its bræðsluhitastig. This property is crucial in various scientific and industrial applications, such as metallurgy, food processing, and material science, where precise temperature control is essential for manipulating the physical state of materials. The concept is the inverse of freezing point, which is the temperature at which a liquid solidifies.
