Melting-temperature refers to the temperature at which a solid substance melts and becomes a liquid. There are several synonyms for melting-temperature including fusion point, melting point, liquefaction point, and thawing point. These terms are frequently used in various fields such as chemistry, materials science, and metallurgy to describe the behavior of different materials. The melting-temperature can be affected by several factors like pressure and impurities present in the substance. Understanding the melting-temperature of different materials is crucial for the development of new products, processes, and technologies that rely on the controlled melting and solidification of materials.
