My mother always asks me not to fill the ice cube tray with water to the brim because it’ll expand and break the box. But doesn’t matter shrink in volume when heat is dissipated, so why does the ice cube expand?
Sorry in advanced, if I word it incorrectly, English is not my first language. Thank you.

The first answer here is right on, but if you really want to blow your mind, think about how the world would work if this wasn’t the case. For instance, nothing could live in a lake ina temperate climate if the ice sank, as the surface would continually cool, freeze, and sink, eventually freezing the entire lake. Instead, the already frozen ice stays next to the cold air and insulates the water underneath.
