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))
Examples include Silicon, which is used in various electronic and technological applications; Bismuth, which in alloys and compounds can be found in chemical and pharmaceutical applications; Antimony; and Gallium.
no, most liquids expand as their temperature rises, but water starts to expand with cooling below 4 degrees celsius through its freezing process. does anything else expand as it freezes?
yes because hydrogen and oxygen are the only ones that have the ability
it is because of molecular arrangment so it expands when frozen
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.
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.
studyisland answer : water
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.
When water freezes it expands, the only substance know to do so when it changes from a liquid to a solid.
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.
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.
Water has many unique properties that enabled life to evolve on Earth. The one that is unique is that it expands when it freezes, thus lowering its density. This means that ice floats on water. It is the only compound or element where the solid form floats on the liquid form.
Only one liquid expands when heated and thats water the most common liquid.
Because the volume of frozen water (Ice) is more than in the liquid form. therefore an ice cube replaces more water hence it floats on the surface of water.
Only 2 percent of fresh water is frozen in glaciers.
Water ice is the most commonly met substance which expands when cooled, even if in the case of ice, it is over a limited temperature range. Additionally, several elements also do so. Ga, Si, Sb, Ge, Bi are the only ones I know of.
