Some of the hydrogen bonds between the water molecules break and three-dimensional hydrogen bonded structure is broken. This causes the number of molecules per unit volume to increase (this is exceptional for water) and thus intermolecular distance decreases.

What happens to water when it is allowed to cool down below 0 degrees Celsius?
A change of phase from the liquid water to solid water (ice); the physical properties are of course different. The molecules in the unfrozen water are moving fast, but as it starts to cool off, the molecules begin to slow down until they don't move at all, thus, freezing.
What is the process called when water turns into ice?
Melting. The ice molecules start to move more than in its solid state. This is also the melting/freezing point (0 degrees Celsius).
Which statement is true regarding the motion of liquid water molecules and ice molecules?
Liquid water molecules exhibit a greater amount of motion than ice molecules.
How does ice turn to water?
When heated, energy is added causing the particles to move faster and loosen bonds therefore turning the solid state into water.
How does snow turn into ice?
when H2O (water) hits snow it turns to ice
What happens when ice melts?
It turns into water and the molecules becomes less densely packed
When water turns to ice are new molecules formed?
No, when water turns to ice, no new molecules are formed. The molecules in water rearrange themselves into a crystal lattice structure when they freeze, but the individual water molecules remain the same.
What happens to the packing of the molecules when water turns from ice to water?
The Molecules(Atoms) stretch their bonds so they spread further apart from each other.
What happens when you put ice cream in the refrigerator what happens to the molecules and the energy?
the molecules freeze and it turns to the freezing point
What happens to water when it is dense?
It turns to ice or heavy water.
Why are molecules closer when its a solid?
molecules that start closing together turn into solid example: think of water, when molecules are loose the water is liquid but when the molecules are packed together the water turns into ice
What happens to the water molecules when the air above gets cold?
the water molecules get cold and expand and turn into ice
Can you give me the characteristics of freezing?
The characteristics of freezing is when water (or any other liquid) turns into a solid. This happens when the liquid gets cold and the molecules get closer together. When the molecules get closer together, they form a solid (ice).

What happens to water molecules as ice melts in terms of kinetic molecular thery?
As the ice melts, the water molecules gain energy, causing them to move more quickly.
What happens to the motion of the particles in a block of ice at it finishes melting?
it turns into water
What happens to the water molecules in an ice cube when it is removed from a freezer?
the temperature increases
