1、第二章四、计算题1.在常压和0℃下，冰的熔化热是334.4Jg-1，水和冰的质量体积分别是1.000和1.091cm3g-1，且0℃时水的饱和蒸汽压和汽化潜热分别为610.62Pa和2508Jg-1，请由此估计水的三相点数据。解：在温度范围不大的区域内，汽化曲线和熔化曲线均可以作为直线处理。对于熔化曲线，已知曲线上的一点是273.15K，Pa；并能计算其斜率是PaK-1熔化曲线方程是对于汽化曲线，也已知曲线上的一点是273.15K，610.62Pa；也能计算其斜率是PaK-1汽化曲线方程是解两直线的交点，得三相点的数据是：Pa，K2.试由饱和蒸汽
2、压方程（见附录A-2），在合适的假设下估算水在25℃时的汽化焓。解：由Antoine方程查附录C-2得水和Antoine常数是故Jmol-1六、证明题各个公司可以自行设计各种单据，并将单据内容与结果列示在“实验过程中使用的表格”中，可以注明单据设计人与单据使用效果。SafetySupervisionBureauoftheparty'smasslineeducationalpracticereformprogramtopromotetheimplementationoftherectification,establishanewsystemtowo
