It can still break things but now it’s pressure from the outside pushing in. From what I know, water is the only substance that occupies more space upon freezing than it does as a liquid. It's greatest density is at 4 C, so it expands at temperatures higher and lower than that. This physical fact creates some interesting phenomena in nature beyond ice forming at the surface of a body of water. mcneely |
