Reply to comment by kemptonite1 in Eli5: Some ice cream recipes put ice + salt outside the recipient to make it cool faster. But in the winter, salt is put on snow on the street to melt faster. Why one make cool and other melt? by zimobz
How does it lower the freezing temperature before the ice melts? The salt makes it melt because you are adding weight, and the salt decreases the viscosity in the chamber making it easier to 'grind', which in turn facilitates the melt process because it adds energy.
No?
