Nope. Silicon(Si), Gallium(Ga), Antimony(Sb), Bismuth(Bi) and acetic acid(CH3COOH, vinegar) all expand on freezing as well. Moreover, silicon expands more than water on freezing (10% compared to waters 8%). The trick to this is that any substance with an open tetrahedral molecular structure will also expand upon freezing. (Perhaps phosphorus oxide(s))
Only one liquid expands when heated and thats water the most common liquid.
The difference is the temperature. Temperature is a measure of average molecular kinetic energy, or in layman's terms, the average speed of the molecules. Molecules that are moving very quickly are "hot", while when the molecules move slowly they are "cold". This is in contrast to phase changes, which occur when water, or any other substance, is converted from one state of matter (water, liquid, or gas) to another.
studyisland answer : water
Water is unique in that it does not get denser as it freezes. This unique fact has allowed life to evolve on the planet. If ice was more dense then water, we would not have ice on top of water. it would freeze and fall to the bottom of the lake, ocean or whatever and kill everything below.
Yes, water does frezee as it expands because of the presure. For example, if there was a hole in a rock and you put water in the rock and let it sit over night on a cool night the rock might crack. This proves that the pressure of ice freezing is higher than the rock's pressure.
Yes, water is unique in that it is the only substance that expands when frozen. Therefore ice will be less dense in terms of water molecules than room temperature water or heated water
Water is the only liquid that expands when frozen.
Water actually becomes less dense, or expands, when frozen. When liquid water reaches it's freezing point, the water molecules rearrange themselves into a lattice structure. Due to the nature of the water molecules, they arrange themselves in such a way as to make it less dense than it was in it's liquid form, which is why ice floats on top of liquid water.
Water is the only substance that the solid form is less dense than the liquid. This means that it floats. This is very useful because otherwise, the whole ocean would be frozen!
No, not exactly. Water expands when it is frozen, so a gallon containing only liquid water and a gallon containing a mix of liquid and frozen water will have different volumes when the liquid melts. That is, the second gallon will be less full, as the water contracts when it melts.
No. There are two main differences (and most others follow on from them): the temperature is lower so the frozen water is solid rather than liquid and the density has decreased (the same volume of water will have expanded).
Frost wedging occurs in small cracks in the rock where water seeps in. The water then freezes and expands (fun fact: water is the only knowns natural substance that expands when freezing, and is also the only substance capable of existing in all three basic states of matter--liquid, solid, and gas--at naturally occurring temperatures), which then splits--or "wedges--the rock apart. I've attached an image for graphic demonstration.

non flammability but i only got one answer
Only 2 percent of fresh water is frozen in glaciers.
They all are made of water. Howewer snow is only frozen rain. Ice is simple frozen water.
Answer: When any substance goes through a phase change only its state is changed, it is still the same combination of element's.
