ELI5: Why does salt melt ice on roads, but adding salt to water makes it take longer to boil?
I understand that putting salt on winter roads lowers the freezing point of water, which makes sense for why it melts the ice.
But I also read that adding salt to a pot of water raises its boiling point.
Why does adding the exact same substance cause these two opposite-seeming shifts in temperature thresholds?
What is the salt actually doing to the water molecules in both situations?
