Physical Properties of Water

Property	Value	Temperature (°C)	Effect and Significance
Density	0.9999	0	Solid form is less dense than its liquid form; ice floats at the surface of liquid water
	1.000 g/mL	3.98
	0.9971 g/mL	25
	0.9584	100
Viscosity	I. 79 cP	0	Hot molasses flows much faster than cold molasses
	0.89 cP	25
	0.28 cP	100
Surface tension	75.6 dyn/cm	0	Water bugs (striders) seem to skitter across this skin as if ice-skating. You can actually float a pin on water, if you carefully lay it across the surface
	72.5 dyn/cm	25
	58.9 dyn/cm	100
Dipole moment	1.8546 D		Reflects the polarity of water molecule
Specific heat	1 cal/g/°C		Water can absorb a substantial amount of heat while its temperature rises only slightly
Latent heat of fusion	80 cal	0
Latent heat of vaporization	540 cal	100
Boiling point	100°C at 1 atm
