How Salt Melts Ice on Roads While Making It Even Colder

How does salt melt ice on the road when the slush it leaves behind is colder than the ice was? Salt releases no heat at all; it quietly changes the temperature at which water freezes. You will learn why zero degrees is really a balance between molecules leaving and joining the ice, how dissolved salt particles tip that balance toward melting, and why the effect depends on particle count rather than the substance. The video also covers why salt and ice were used to make ice cream, why road salt stops working around minus ten, why calcium chloride is used in harder frosts, and how the same rule shapes sea ice and antifreeze.
