Water molecules are V-shaped with a partly negative charge on the oxygens and partly positive charges on the hydrogens. These two factors cause strong bonds between the oxygen and hydrogen atoms of surrounding water molecules, and a higher boiling point to cause enough vibration for them to break apart and vaporize. Carbon dioxide, however, is line-shaped, so it doesn't have the partial charges. Therefore, the bond is weaker between molecules.
