When water freezes some interesting things happen. A pond can transform into an ice skating rink, rain turns to snow, and ice cubes transform a pot of hot steaming tea into a refreshing summer beverage. Outside, the temperatures need to drop to 32 degrees F before rain freezes into snow flakes. Inside we fill up an ...
When water freezes, the molecules slow down and assume a fixed position, although not quite in the way that one might think. Water is made of molecules with two hydrogen atoms and an oxygen atom, but those molecules don't just stop moving as units.
The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. In theory, the two temperatures would be the same, but liquids can be supercooled beyond their freezing points so that they don't solidify until well below freezing point.
Describe what happens to water molecules as they move from being water vapor near the can to ice on the can. ... Point out that when water freezes, the water molecules have slowed down enough that their attractions arrange them into fixed positions. Water molecules freeze in a hexagonal pattern and the molecules are further apart than they were ...
The fact that water expands upon freezing causes icebergs to float. The fact that water reaches a maximum density at about 4°C causes bodies of water to freeze on the top first. Then the further expansion as a part of the phase change keeps the ice floating with some 8% of its mass above the surface.
When water freezes, the molecules are locked into place in a crystal structure, and it turns into a hard solid, or ice. The ice is hard because unlike in water, where the individual H2O molecules ...
Thus slow-freezing ice rejects impurities including air, minerals, and salts, and pushes them out of the way. This is why the last part of the ice to freeze is where any trapped air and impurities are. Most ice cubes are cloudy in the middle because the water is freezing on all four sides of the container; outside-in.

when you boil water you set the temp to 100 degrees C and it stays 100 degrees C because that is the water's boiling point describe what happens to the average kinetic energy of water molecules as water freezes
Water can exist as a solid (ice), liquid (water) or gas (vapour or gas). Adding heat can cause ice (a solid) to melt to form water (a liquid). Removing heat causes water (a liquid) to freeze to form ice (a solid). When water changes to a solid or a gas, we say it changes to a different state of matter. Even though the water’s physical form changes, its molecules stay the same.
