When you have a cup with ice cubes in it and you leave it sitting there for a while, the ice cubes all sort of meld into one big ice cube. Why? How is it warm enough for the ice to melt, but then cold enough for it to re-freeze?
In: Chemistry
My answer to this would be: the outside of the pile of ice is getting warmer and melting Because it is exposed to warm air. The melted water drips down to the unexposed middle of the pile where it is still cold and at freezing temperature. Then it freezes again and sticks the cubes together.
