第 1 页 水与水蒸气
1kg水从常温转化为100℃水蒸气需消耗多少度电？
水从液态转换为蒸汽，需要的热量为两部分：
设常温温度为20℃，压强为一个大气压强，
已知水的沸点是100℃，水的相对分子质量为18g/mol，水的比热是4.2kj/(kg·℃)，气化热是40.8kj/mol。则：
1. 从20℃水变成100度水所需能量
=1×（100-20）×4.2=336千焦；
2. 从100℃水变成100℃水蒸气液体分子要克服分子势能做功，所需能量
=40.8×（1000/18）=2266.7千焦。
合计所需总能量
=336+2266.7=2602.7千焦。
1度=1000瓦时=3600千焦，
2602.7千焦/3600千焦=0.723(度)，
即：将1公斤20度的水转化为100度水蒸气需消耗0.723度电。

一.什么是水和水蒸气的焓?
水或水蒸气的焓h，是指在某一压力和温度下的1千克水或1千克水蒸气内部所含有的能量，即水或水蒸气的内能u与压力势能pv之和(h=u+pv)。水或水蒸气的焓，可以认为等于把1千克绝对压力为0.1兆帕温度为0℃的水，加热到该水或水蒸气的压力和温度下所吸收的热量。焓的单位为“焦/千克”。
(1)非饱和水焓：将1千克绝对压力为0.1兆帕温度为0℃的水，加热到该非饱和水的压力和温度下所吸收的热量。
(2)饱和水焓：将1千克绝对压力为0.1兆帕温度为0℃的水，加热到该饱和水的压力对应的饱和温度时所吸收的热量。饱和温度随压力增大而升高，因此饱和水焓也随压力增大而增大。例如：绝对压力为3.92兆帕时，饱和水焓为1081.9 x 103焦/千克;在绝对压力为9.81兆帕时，饱和水焓则为1399.3 x 103焦/千克。

一.什么是水和水蒸气的焓?
水或水蒸气的焓h，是指在某一压力和温度下的1千克水或1千克水蒸气内部所含有的能量，即水或水蒸气的内能u与压力势能pv之和(h=u+pv)。水或水蒸气的焓，可以认为等于把1千克绝对压力为0.1兆帕温度为0℃的水，加热到该水或水蒸气的压力和温度下所吸收的热量。焓的单位为“焦/千克”。
(1)非饱和水焓：将1千克绝对压力为0.1兆帕温度为0℃的水，加热到该非饱和水的压力和温度下所吸收的热量。
(2)饱和水焓：将1千克绝对压力为0.1兆帕温度为0℃的水，加热到该饱和水的压力对应的饱和温度时所吸收的热量。饱和温度随压力增大而升高，因此饱和水焓也随压力增大而增大。例如：绝对压力为3.92兆帕时，饱和水焓为1081.9 x 103焦/千克;在绝对压力为9.81兆帕时，饱和水焓则为1399.3 x 103焦/千克。

一.什么是水和水蒸气的焓?
水或水蒸气的焓h，是指在某一压力和温度下的1千克水或1千克水蒸气内部所含有的能量，即水或水蒸气的内能u与压力势能pv之和(h=u+pv)。水或水蒸气的焓，可以认为等于把1千克绝对压力为0.1兆帕温度为0℃的水，加热到该水或水蒸气的压力和温度下所吸收的热量。焓的单位为“焦/千克”。
(1)非饱和水焓：将1千克绝对压力为0.1兆帕温度为0℃的水，加热到该非饱和水的压力和温度下所吸收的热量。
(2)饱和水焓：将1千克绝对压力为0.1兆帕温度为0℃的水，加热到该饱和水的压力对应的饱和温度时所吸收的热量。饱和温度随压力增大而升高，因此饱和水焓也随压力增大而增大。例如：绝对压力为3.92兆帕时，饱和水焓为1081.9 x 103焦/千克;在绝对压力为9.81兆帕时，饱和水焓则为1399.3 x 103焦/千克。
