Cooling and heating

Change of state is a physical change where intermolecular bonds are broken. Melting and boiling points are determined by vapor pressures of the solid and liquid states. At 0 degrees Celsius, ice and liquid water have the same vapor pressure. At 100 degrees Celsius, water vapor and atmospheric pressure are equal.

Super cooling is cooling of liquid below freezing point and it occurs when the particles lack the internal arrangement to solidify at freezing point.

Super heating is heating of a liquid is raised above its boiling point and it occurs when vapor bubbles fail to form and it may suddenly boil violently when vapor bubbles do form.
