its because the salt causes a decrease in the freezing point of water ie 0 degs changes to -20 degs so since ambient relative temperature i much higher than in no salt condition,it melts.
Rock salt, for sure!
i think that they will turn in a river
rock salt melts ice faster because every winter my mom puts rock salt on ice and it melts within 2 seconds so i think rock salt melts the fastest
Rock salt because it is a larger, coarser salt than table salt. It is also safer than salt water because it will provide a surface to walk on. Salt water still has the ability to freeze, so it is not a good de-icer.
it melts
A serous difference doesn't exist.
The stuff you buy for that purpose is just plain, ordinary salt.
rock salt
Sand and sugar are two examples of solids that can be poured easily. When poured, their small particles flow and settle into molds or containers, taking the shape of the surface they are poured onto.
Salt lowers the freezing temperature of water to some extent, so ice at 0°C can be melted to some porportion of ice at a lower temperature and brine.
you know what, i'd presume so
It is the salt itself that melts ice.
