Sulamiskäyrään

Sulamiskäyrään is a Finnish term that translates to "melting curve" or "fusion curve" in English. It refers to a graphical representation of the relationship between temperature and pressure at which a substance exists in equilibrium between its solid and liquid phases. As pressure increases, the melting point of most substances also increases, and this trend is depicted by the sulamiskäyrään. For water, however, the sulamiskäyrään has a negative slope, meaning its melting point decreases with increasing pressure due to its unique crystal structure. The sulamiskäyrään is a fundamental concept in thermodynamics and phase diagrams, providing crucial information about a substance's behavior under varying conditions. Understanding the sulamiskäyrään is essential in fields such as materials science, geology, and chemistry for predicting phase transitions and material properties. It helps determine the conditions under which a solid will melt or a liquid will freeze.
