Molecules in all states of matter have a Kinetic Energy that is proportional to temperature.
As water is cooled, that Kinetic Energy, the translation, rotational and vibrational, decreases.
When water reaches 0 degrees C at normal pressure, the Kinetic Energy remains constant as freezing proceeds.
Removing more heat energy decreases the potential energy of the molecules by changing their positions relative to one another. Attractive forces between molecules move them into preferred positions which are identical for every molecule. In the process a pattern emerges and a regular array of molecules is assembles in the crystalline structure we know as ice.
Unlike most other substances, this rearrangement of water keeps the molecules further apart than the average separation in the liquid. That is why ice floats, it has a lower specific gravity (density) than liquid water.
Who ever answered this is dumb because this is wrong;D

As water is cooled, Kinetic Energy, including the translation, rotational and vibrational, decreases. Potential energy decreases as well, going from near zero in the gas to a negative value that is a fraction of the kinetic energy.

When water freezes does the molecules ionize?
No, they do not.
When water freezes to form ice what connect the water molecules?
hydrogen bonds
What will happen to the molecules when it freezes?
When a molecule freezes, the kinetic energy of that molecule decreases, and the molecules do not move as fast. It is chemically unaltered, but on the phase has changed, making it a physical change.
Why do cracks in a rock get bigger if water freezes in them?
Frozen water molecules are larger and expand. In liquid form H2O is smaller
What will happen when atom and molecules of substance melt freeze boil or condense?
When a substance melts, the molecules move more freely and when it freezes, they move more slowly. When a substance boils and becomes a vapor (gas), the molecules again move faster than when in the liquid state, and when the vapor condenses, the molecules move slower.
When water freezes does the molecules ionize?
No, they do not.
What happens to the arrangement of water molecules as water melts and freezes?
When water freezes the molecules come together and become more orderly. When water melts the molecules loosen apart.
What is the freezing temperature that freezes water molecules?
Water freezes at 0o Celsius, or 32o Fahrenheit.
When water freezes to form ice what connect the water molecules?
hydrogen bonds
When water freezes to form ice what connects the water molecules?
hydrogen bonds
Does ice undergo a chemical change when it freezes?
No. Ice undergoes a physical change when it freezes, such that its molecules align in a lattice that is less dense than the liquid state.
What will happen to the molecules when it freezes?
When a molecule freezes, the kinetic energy of that molecule decreases, and the molecules do not move as fast. It is chemically unaltered, but on the phase has changed, making it a physical change.
What happens when molecules lose energy?
They get colder.
Why isn't the freezing point of a liquid a chemical property?
Because when something freezes, the atoms and molecules don't undergo a chemical change, they go through a physical change. By this, I mean that the individual atoms and molecules lose kinetic energy (energy that makes you move) in order to freeze. There is no chemical change here. Rather, the molecules and atoms are slowing down physically.
How does the volume of a kilogram of water when change when it freezes?
it changes because when it freezes, the molecules within the water slows down thus changing the placement of it, which also changes the over size or volume of water.
Do soap bubbles last longer in hot or cold days?
it may not last longer because when it freezes the kinetic energy of the molecules move slower and freezes therefore the bubble may pop.
When liquid water freezes into ice it's molecules align to form what?
Ice is a material with crystalline structure.
