A: (a)HO(l,373K,100kPa)与(b)HO(g,373K,100kPa)
B: (a)HO(l,373K,200kPa)与(b)HO(g,373K,200kPa)
C: (a)HO(l,374K,100kPa)与(b)HO(g,374K,100kPa)
D: (a)HO(l,373K,100kPa)与(b)HO(g,373K,200kPa)
A: (a)HO(l,373K,100kPa)与(b)HO(g,373K,100kPa)
B: (a)HO(l,373K,200kPa)与(b)HO(g,373K,200kPa)
C: (a)HO(l,374K,100kPa)与(b)HO(g,374K,100kPa)
D: (a)HO(l,373K,100kPa)与(b)HO(g,373K,200kPa)
举一反三
- 已知水的两种状态A(373K,101.3 kPa,g),B(373 K,101.3 kPa,l),则两者化学势的关系为( ) A: μA=μB B: μA>μB C: μA<μB D: 两者不能比较
- 在373 K、压力为100 kPa时,1.0 g[tex=3.071x1.357]09kO2yLk3H8In1fhN7sJQg==[/tex]经下列不同的过程变为373 K、100 kPa的[tex=3.214x1.357]KCyUmAHtIiN5Ii+ywoUnRQ==[/tex],请分别求出各个过程的[tex=4.714x1.214]B3r/S5LL6OrdNsU/3IqPq3kPuTLcJeODOvQEJkaV7+Y=[/tex]和Q。先在373 K、外压为50 kPa下变为汽,然后可逆加压成373 K、100 kPa的汽
- 比较下列二种状态水的化学势:(a) 373 K,101.3 kPa,液态; (c) 373 K,202.6 kPa,液态;μ(c)与μ(a)相差多少?
- 比较下列二种状态水的化学势:(a) 373 K,101.3 kPa,液态; (b) 373 K,101.3 kPa,气态;u(a)与u(b)谁大?
- △G=△A的过程是:() A: HO(l,373K,p)→HO(g,373K,p); B: N(g,400K,1000kPa)→N(g,400K,100kPa); C: 等温等压下,N(g)+3H(g)→NH(g); D: Ar(g,T,p)→Ar(g,T+100,p)。
