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.
A chemistry professor explains the science that makes salt a cheap and efficient way to lower freezing temperature. A chemistry professor explains the science that makes salt a cheap and efficient ...
Ice cream was originally made using very intensive labor and it often took one individual hours to make. Johnson had invented the hand cranked ice cream churn as a way to make ice cream faster and easier than by hand. [4] The patent number for the Artificial Freezer is US3254A. [5] It was patented on September 9, 1843, and antedated on July 29 ...
The meaning of the name ice cream varies from one country to another. In some countries, such as the United States and the United Kingdom, [1] [2] ice cream applies only to a specific variety, and most governments regulate the commercial use of the various terms according to the relative quantities of the main ingredients, notably the amount of ...
So what are some alternatives to ice melters? Michigan Concrete Association recommends a regular salt like Morton table salt instead of an ice melter because it’s 100 percent sodium chloride (NaCl).

The surface is treated primarily by snow removal. Roads are also treated by spreading various materials on the surface. These materials generally fall into two categories: chemical and inert. Chemical (including salt) distribution induces freezing-point depression, causing ice and snow to melt at a lower temperature. Chemical treatment can be ...
Salt for use of melting ice and snow works through a phenomenon called freezing-point depression, the lowering of a substances freezing point after the addition of solutes. When road salt is added to roads, aside from providing better friction for vehicles on the road, it also dissolves in the water of the ice, resulting in a lower freezing point.
