    已知373.15K下H2O(l)的标准摩尔汽化焓为40.67kJ/mol。2molH2O(l,373.15K,100kPa)在定温定压下汽化为H2O(g,373.15K,100kPa)时,过程的Q,W,ΔU,ΔH,ΔS,ΔG为()
    A: Q=81.34kJ,W=-81.34kJ,ΔU=0J,ΔH=0J,ΔS=218J·K-1, ΔG=0 J
    B: Q=40.67kJ,W=-3.10kJ,ΔU=37.57,ΔH=40.67kJ,ΔS=109J·K-1, ΔG=0 J
    C: Q=40.67kJ,W=-40.67kJ,ΔU=0 J,ΔH=0 J,ΔS=109J·K-1, ΔG=0 J
    D: Q=81.34kJ,W=-6.20kJ,ΔU=75.14kJ,ΔH=81.34kJ,ΔS=218J·K-1, ΔG=0 J
