Good Question: How Does Salt Melt Ice?

Salt melts ice by making it easier for the ice to turn into water, just like how a hot bath helps you get warm faster.

When salt is added to ice, it mixes with the ice and makes it harder for the ice to hold on to its shape. Think of the ice as being really cold and stiff, like a stiff cookie. When you add salt, it's like giving the cookie a little push, it starts to get softer and easier to break apart.

Imagine you're playing with ice cubes in your glass on a hot day. The ice is trying to stay solid because it’s cold. But if you pour some salt over the ice, it starts to melt faster, just like how adding sugar makes your lemonade sweeter and easier to drink.

Salt changes the temperature of the ice, not by making it warmer, but by letting it go from being a hard block into flowing water more easily. This is why we use salt on icy roads in winter, it helps make them safer for cars and people walking.
