The water molecules are formed of hydrogen and oxygen atoms. However, as the temperature drops the hydrogen atoms slow down and form very tight bonds, but without the presence of oxygen atoms. This creates a more open molecular network, which is why frozen water is less dense than when in liquid form.
by 'the law of non-compress ability of liquid' a liquid can neither be compressed nor be expanded. Between 3'C and 0'C water does expand with a decrease in temperature. Water at 3'C is the densest; water at 0'C is the lightest. This is the only interval for Ice I on which it expands with decreasing temperature.
No, the molecules move farther apart
No. Most liquids contract when they freeze. Water is unique in that it expands.
no
Since ice is a solid, there is no free motion between water molecules due to the intermolecular bonds holding the molecules in place. Because of this, water molecules "vibrate" in place when it is frozen. The colder it gets the less water vibrates.
The water molecules expand when the temp. drops.
Any liquid or solid shrinks when frozen; the molecules contract. Molecules expand when thawed.
Frozen water molecules are larger and expand. In liquid form H2O is smaller
Water expands at the equator because it is warm there, and warm molecules expand. Warm molecules expand and cold molecules decrease in size.
If the food has water in it then it will expand.
poo
expands because hydrogen bond operates the molecules and increase the average distance between molecules
yes, this is why if you put a filled to the brim cup of water in the freezer, it overflows when it is frozen....
Water expands when it is cold because the water molecules found in water expand in the cold.
Yes, due to the orientation of the molecules. In the liquid state water molecules are in disorder, but when they are solid (ice), they form a regular hexagonal patterns that naturally surround empty space. The presence of this unoccupied center accounts for the expansion.
Like all molecules, a molecule of H20 is in constant motion; 'hot' molecules move faster than 'cold' molecules. If the molecules move slowly enough the substance appears stationary to us (frozen water) and if they move quickly enough they will expand to fill their container (vapor or gas water.)
The water molecules expand when the temp. drops.
