Freezing is a physical process in which a liquid changes into a solid after losing sufficient heat energy. It is one of the key phase changes of matter and occurs when the temperature of the liquid reaches or drops below a specific value called the freezing point. [1-4]
Science of Freezing Water and foods freeze differently. When water freezes and ice crystals form there is actually a small amount of heat produced. The temperature of the water remains at 32°F as the ice crystals grow, and then a rapid temperature drop occurs as the ice crystals cool. Because foods are a complex mixture of many substances, their freezing point is below the freezing point of ...
Freezing Point The temperature at which a substance freezes is known as its freezing point. Freezing point is a physical property of matter. The freezing point of pure water is 0°C. Below this temperature, water exists as ice. Above this temperature, it exists as liquid water or water vapor. Many other substances have much lower or higher freezing points than water. You can see some examples ...
