• Water dissolves many polar non-ionic substances, such as ethanol (CH3CH2OH) and glucose (C6 H12O6), by forming H bonds to them.

• Water even dissolves nonpolar gases such as N2 and O2  through dipole-induced dipole forces.

Thermal Properties of Water

• Water has an exceptionally high specific heat capacity. (4.184 J/g.K)

• Strong H bonds are responsible for much of waterís high specific  heat capacity.

• The larger the heat capacity, the less the temperature rises when a  substance absorbs a given amount of heat.

• Strong H bonds also give water an exceptionally high heat of  vaporization and a high surface tension.
