Solution

You can think of milk as water that contains salts, sugars, fats, and other molecules. Just as salt water boils at a slightly higher temperature than pure water, milk boils at a slightly higher temperature, too. It's not a huge temperature difference, though, so expect milk to boil about as quickly as water.
