Why does salt and ice make my beers colder?

Question

How does salt get an ice-water mixture to be colder? I mean... I use salt to melt ice on the road in the winter time. Salt to bring ice at a higher temperature so, it's in a state of liquid form and not solid. I could never figure this out.

Answer 1

Because it is a solid that is frozen. Simple, it simply forms a carbonic gas through osmosis that delivers you a very, cool drink.

Answer 2

Salt lowers the melting point of ice, and takes the solid to below the ambient temperature, so it melts. It does not raise the temperature!
