Inside each person lives two wolves. One is loyal, kind, respectful, humble and open to the mystery of life. The other is greedy, jealous, hateful, afraid and blind to the wonders of life. They are in battle for your spirit. The one who wins is the one you feed.
*Water* expands when it freezes. I'm not sure that *all* liquids do. Though I'm hard pressed to think of a liquid that isn't water, or doesn't contain water that freezes.
Freezing is simply the state change of a liquid congealing and becomeing a solid. For example, water freezes at 0 degrees Celsius.
Iron's freezing point is around 1500 degrees Celsius.
WATER expands when it freezes, and is one of the only substances that does.
Most substances do not, and, in fact, shrink and become denser when they freeze.
generally for matter there are three states, gas ---> liquid ---> solid, for almost all substances as you go from left to right, things contract. One major exception to this rule is water. The reason for this is that crystals are formed in the solid by hydrogen bonds due to the dipole nature of the molecule (one negative part, the oxygen, and one positive part, both hydrogens).
Water does shrink as you cool it, up to a certain point, somewhere around 3 degrees if I remember well, when it starts expanding
one easy way of looking at it from an atomic level is to think about molecules going around all over the place. As you add heat, you excite them and they take up more room, they move around more, this is a gas. As you cool things down, the molecules get sluggish and move less, they take up less room, this is a liquid. If you cool things down ever more these molecules take up even less room, they never stop moving (unless you hit absolute 0), but they move less and less and take up even less room and you have a solid. The reason water is different is that instead of just colapsing, water is able to build structures when they stop moving enough.

Nope Leah, When I put my water in the ice cube trays and freeze them, alot of the time, the ice cubes have spaces around them depending on how full I fill hte tray.
