? 冰是一种透明的六方晶系的晶体结构。纯净的水在正常的大气压下，到0?就会结

冰。若水中含有杂质，压力增加，水的结冰点会下降。

? 冰的融点即为水的冰点，随着大气压升高，冰的融点也升高。

? 冰的融解热为331.6,335.7kJ/kg，通常取335 kJ/kg

? 冰的比重与其温度、冰形成时的环境压力、冰中有否含有空气泡和水的纯度有关。

水结成冰后，密度减少，体积增大。图1为大气压下水(冰)与温度的关系。

? 一般在实用上，冰的温度从0?到-20?时，其平均比热容取2.1kJ/kg?K，而水的比

热容为4.2kJ/kg?K，仅为水的一半。

? 冰的热导率与其温度有关，随着温度的降低而增加。一般工程计算取2.22w/(m?k)

F3 Viscosity decreases with pressure

(at temperatures below 33?C)

Viscous flow occurs by molecules moving through the voids that exist between them. As the pressure increases, the volume decreases and the volume of these voids reduces, so normally increasing pressure increases the viscosity.

Water's pressure-viscosity behavior [534] can be explained by the increased pressure (up to about 150 MPa) causing deformation, so reducing the strength of the hydrogen-bonded network, which is also partially responsible for the viscosity. This reduction in cohesivity more than compensates for the reduced void volume. It is thus a direct consequence of the balance between hydrogen bonding effects and the van der Waals dispersion forces [558] in water; hydrogen bonding prevailing at lower temperatures and pressures. At higher pressures (and densities), the balance between hydrogen bonding effects and the van der Waals dispersion forces is tipped in favor of the dispersion forces and the remaining hydrogen bonds are stronger due to the closer proximity of the contributing oxygen atoms [655]. Viscosity, then, increases with pressure. The dashed line (opposite) indicates the viscosity minima.

The variation of viscosity with pressure and temperature has been used as evidence that the viscosity is determined more by the extent of hydrogen bonding rather than hydrogen bonding strength.

Self-diffusion is also affected by pressure where (at low temperatures) both the translational and rotational motion of water anomalously increase as the pressure increases.
