States of Water

Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.

Water freezes when the intermolecular forces are greater than t...

Water can exist in any of the three classical states of matter—solid, liquid, or gas.

The state depends on the intermolecular forces that attract molecules to each other and the temperature, which measures the average molecular kinetic energy. 

Lowering the temperature reduces the kinetic energy. At 0 °C, hydrogen bonds cause the m...
