What is the definition of Melting / freezing point

• the temperature at which a substance changes from a liquid to a solid or a solid to a liquid by the loss or addition of heat; for water this temperature is 0°C
• the decimal measuring system based on the meter, liter, and gram as units of length, volume (capacity), and weight or mass
• a combination of two or more substances that can be easily separated in some physical way
• properties of matter that can be observed, measured, or changed without changing the matter itself
• floating or sinking when compared to water
