The normal melting point is the temperature at which a solid substance changes into a liquid form at a standard atmospheric pressure of one atmosphere or 101.325 kPa. There are several synonyms that can be used to describe this property, such as melting temperature, melting point, and fusion temperature. Other related terms include solidification temperature, freezing point, and crystallization temperature. These terms are commonly used interchangeably in studies involving physical and chemical properties of materials. Measuring the normal melting point is an important aspect of analyzing the characteristics of substances, and can provide valuable information about their behavior and usage in various applications.
