Im going to do my best. Salt lowers the freezing point of water. Think of regular water as little balls, the temperature dropping is like trying to put the balls into a small box and when they can’t get any closer they become ice. Salt are smaller balls that get in between the water and make it so that it has to be colder for the water to become ice.
