Question about ice cubes?

Asked by derektherock42 (191points) March 27th, 2008 from iPhone

This one’s really been bugging me. If coldness contracts and heat expands, why do ice cubes take up more space than the same amount of unfrozen water?

Wikipedia??? I’ll give you a hint, search water or ice.

Its like a bunch of marbles vs jello balls of the same volume. The jello balls would take up less space. The molecules in the ice are more rigid and solid. That’s my laymens answer, anyway.

How don’t you know that. With out that phenomenon life would on Earth would have been impossible.

It’s just how the H2O molecules are set up that they form a structure that makes them expand when they get colder. It’s hard to explain with out a image.

I don’t have a clue what this guy (monsoon) is trying to say. Just ignore that. Jello balls.

“If coldness contracts and heat expands” is a shortcut, a general rule.. it is NOT necessarily true.

@omfg: have you ever made ice cubes in a tray? pretty sure derek’s right. try your suggested experiment.

i think monsoon is trying to convey that h2o as a liquid is more fluid/flexible (like a ball/blob of jello).

This question is way to easy. How about the fact that water doesn’t contract past 4 degrees C. It is unlike any other chemical, it gets less dense and expands as it freezes. Also they form a very specific “honeycomb” like structure as the molecules slow down and the water freezes.
