Workers spreading salt from a salt truck for deicing the road Freezing point depression is responsible for keeping ice cream soft below 0°C. [1]Freezing-point depression is a drop in the maximum temperature at which a substance freezes, caused when a smaller amount of another, non-volatile substance is added.

If your scale says your weight went up overnight, you might wonder: Can you gain weight in one day? Experts give 11 reasons you seemed to gain weight overnight.
Slurry ice with propylene glycol as depressant viewed through a microscope.. Slurry ice is a phase changing refrigerant made up of millions of ice "micro-crystals" (typically 0.1 to 1 mm in diameter) formed and suspended within a solution of water and a freezing point depressant.
“If you have two 1-pound bags of salt, but one bag has big crystals and the other has small crystals, the smaller crystals will melt ice faster,” Ferguson says.
While weight fluctuations in men can be perfectly normal, if they are significant or unexpected it may be cause for concern, according to an expert. Why does my weight fluctuate so much? Skip to ...
Fractional freezing is a process used in process engineering and chemistry to separate substances with different melting points. It can be done by partial melting of a solid, for example in zone refining of silicon or metals, or by partial crystallization of a liquid, as in freeze distillation, also called normal freezing or progressive freezing.
