Why is ice less dense than water?

Asked by el_ricardo_777 about 1 year ago, 3 answers.

Well, my chemistry teacher gave a website link to a website that was supposed to help answer this but it only showed diagrams, but I didn't really know why it's less dense, help's appreciated!

I think its because water is one of the few substances that actually expands as it gets colder. thus there is more volume for the same amount of mass, making it less dense.
