what is the Different between water and Ice?

Question

Please don't tell me water is liquid and ice is solid, answer it in the molecular, infact using biological terms

Answer 1

Of course ice and water are chemically identical consisting of H2O. The two hydrogen atoms attach to the oxygen atom other than in a straight line (not like beads on a string). The electron field surrounding the water molecule is uneven providing it with a "polarity" that makes it much easier to pack many molecules together in a given (rather than arbitrary) arrangement. When water is a vapor (or steam) there is so much vibrational energy that the molecules bounce off each other maintaining a "pressure" depending on their energy (temperature). When the molecules are a liquid, they are very closely packed and are nearly incompressible (even seven miles below the surface of the ocean!). The bulk water expands and contracts only a little with temperature changes. When heat is removed from the water (in a freezer?) the molecules are attracted to each other in a preferred array due to polarity and form long chains of molecules that use up space far less efficiently. The "ice" is less dense and floats on water because the space between chains is filled with a vacuum or gases that weigh very little. When the water is allowed to freeze in open space (a cloud?) the polarity is free to align water molecules in the most preferred orientation; a six sided snow flake. When hoar frost forms on a cold window pane the ice forms in dendrites, like growing Christmas trees. Hope that helps a little.

Answer 2

As with any matter, it has to do with the motion of the atoms contained. In a solid state, there is very little atomic motion, though there is always some minute motion in all atoms until the temperature reaches absolute zero. In a a solid state, matter will conform to a specific shape (say, a block of ice) and will remain that way. With the increase of atomic motion (a rise in temperature) the substance will transform in into a fluid, either a liquid (water) or a gas (steam), and does not conform to a specific shape (a puddle of water has no specific shape).

Answer 3

Water has the chemical formula H2O, meaning that one molecule of water is composed of two hydrogen atoms and one oxygen atom. It can also be described ionically as HOH, with a hydrogen ion (H+) that is bonded to a hydroxide ion (OH-). It is in dynamic equilibrium between the liquid and vapor states at standard temperature and pressure. At room temperature, it is a nearly colorless, tasteless, and odorless liquid. It is often referred to in the sciences as the universal solvent and the only pure substance found naturally in all three states of matter.

A simple but environmentally important and unique property of water is that its common solid form, ice, floats on its liquid form. This solid phase is less dense than liquid water, due to the geometry of the strong hydrogen bonds which are formed only at lower temperatures. For almost all other substances and for all other 11 uncommon phases of water ice except ice-XI, the solid form is denser than the liquid form.

Ice can refer to any one of the 14 known solid phases of water. However, in non-scientific contexts, it usually describes ice Ih, which is the most abundant of these phases in Earth's biosphere. This type of ice is a soft, delicate, crystalline solid, which can appear transparent or an opaque bluish-white color depending on the presence of impurities such as air. The addition of other materials such as soil may further alter appearance. The most common phase transition to ice Ih occurs when liquid water is cooled below 0 °C (273.15 K, 32 °F) at standard atmospheric pressure. However, it can also sublime from a vapor with no intervening liquid phase such as in the formation of frost. Ice appears in varied forms such as hail, ice cubes, and glaciers.

Answer 4

Ice is a water in solid form. It forms at the point of freezing (0 degree celcious).

Water is a liquid which is a tasteless, odorless substance that is essential to all known forms of life.

Answer 5

Water (from the Old English waeter; c.f German "Wasser", from PIE*wod-or, "water"), in its pure form, is a tasteless, odorless substance that is essential to all known forms of life and is known also as the universal solvent. It appears colorless to the naked eye in small quantities, though it can be seen to be blue in large quantities or with scientific instruments[1]. An abundant substance on Earth, water exists in many forms. It appears mostly in the oceans and polar ice caps, but also as clouds, rain water, rivers, freshwater aquifers, and sea ice. Water in these bodies continuously moves through a cycle of evaporation, precipitation, and runoff to the sea. Clean water is essential to human health and is in short supply in many parts of the world (see the section on water and human health).

It plays an important role with many meteorological phenomena. The ice caps of the polar regions are of significance for the global climate and particularly the water cycle.

Answer 6

Temperature

Answer 7

There is no chemical or component difference since water and ice are composed of H2O. The difference, if you want to consider it one is in form only.

Answer 8

Temperature is a bigger difference between water and ice.

Answer 9

When water freezes the molecules compact and harden
