freezing embrace season 2 - Gardening Tips
As global temperatures rise, the freezing line where precipitation changes from rain to snow moves up the mountains, shrinking the area capable of sustaining a seasonal snowpack. Freezing is almost always an exothermic process, meaning that as liquid changes into solid, heat and pressure are released. This is often seen as counter-intuitive, since the temperature of the material does not rise during freezing, except if the liquid were supercooled.
Understanding the Context
The confusion seems to be based on the fact that few people understand how freezing protects food. Here is some information on how to freeze food safely and how long to keep it. 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] A common example of freezing is water turning into ice.

Key Insights
The freezing point of water is 0°C (32°F) at standard atmospheric pressure. To preserve high-quality frozen foods it is important to understand the freezing process. Freezing is one of the easiest, most convenient, and least time-consuming methods of preserving foods. Freezing does not sterilize foods; the extreme cold simply retards the growth of microorganisms and slows down chemical changes that affect quality or cause food to spoil. We explain why freezing rain is the worst of the precipitation types, as far as impacts are concerned.
