Physical properties of water, II
Hydrogen bonds contribute to H2O�s large latent heat of fusion (= 80 cal/g)
Hydrogen bonds contribute to H2O�s very large latent heat of vaporization = 540 cal/g
Solar radiation (insolation) reaching earth may be stored as latent heat in water at earth�s surface
On moon, noon temperature = ~135�C; on earth highest temperature = 57�C
On moon, midnight temperature = ~-155�C; on earth coldest temperature = -68�C
