What do the particles do when the water begins to freeze?

Answer 1

Short Answer:
As water freezes the water particles particles move from a somewhat random (liquid) arrangement into a more orderly crystalline (ice) pattern and give up energy in the process.

Explanation:
Water freezes (at 0 degrees C, 32 degrees F) and liquid water and solid water coexist at the same during the freezing process. In the liquid portion, molecules are still rather mobile, moving around in an irregular diffusive process. In the solid form, molecules are arranged in a regular pattern, the crystalline patter of ice. In the crystal state, the individual molecules stay in specific positions relative to their neighbors.

It is important to note that the kinetic energy of water molecules is proportional to temperature, so the kinetic energy of the ice water molecules is the same as the kinetic energy of the water molecules at the freezing temperature, 0 C. The heat that is removed from water to form ice is potential energy that exists as a consequence of the electrostatic forces between the molecules. The potential energy decreases when the molecules move into positions where attractive forces hold them together more effectively.

Answer 2

As water freezes, its molecules form a lattice-like crystal that resembles a stack of empty boxes. This is unique among molecules, for as the ice melts, water molecules can move into the empty boxes of the lattice, making liquid water more dense than the solid.

Answer 3

the particles begin to move slower because the the water is starting to freeze and a solids particles are packed tightly.

Answer: There are several options: # As water gets less dense below 6C, the particles could sink more readily and fall to the bottom of the container # The ice may freeze as needle like ice crystals (frazil ice) forming a mesh that traps the particles in the final ice mass. # The water may freeze by plating out on the existing ice excluding the particles until they are trapped in the last to freeze bit of water (similar to zone refining of semiconductors)

Answer 4

They move farther apart.
they slow down
the particles expand, creating the ice less dense.
Unlike most elements and compounds, which contract and get denser as they freeze, water expands and gets less dense as its temperature drops below 4° C and it freezes (at 0° C) due to its molecules arranging themselves into crystalline structures.

Answer 5

As water freezes, the water particles begin to move more slowly. If water starts to melt or boil, the particles begin to move more quickly.

Answer 6

The particles in the water when freezing link together, causing the frozeness.

Answer 7

THEY GO CLOSER
