consider 2.0 mole of a monatomic ideal gas that is taken from
state A(Pa=2atm Va=5L) to state B(Pb=1atm Vb=20L) by different pathways.
Path1:stateA (Pa=2atm Va=5L)to state C(Pc=2atm Vc=20L)to state B(Pb=1atm Vb=20L)
Path2:stateA (Pa=2atm Va=5L)to state D(Pd=2atm Vd=5L)to state B(Pb=1atm Vb=20L)
12.calculate q(KJ) of path1 and path 2
A)q1=3.04 q2=2.48 B)q1=1.62 q2=4.56 C)q1=6.27 q2=2.45 D)q1=4.56 q2=3.04
E)q1=2.56 q2=4.24
13.calculate W(KJ) of path1 and path 2
A)w1=-3.04 w2=-1.54 B)w1=-2.74 w2=-3.62 C)w1=-2.52 w2=-3.57 D)w1=-3.04 w2=-2.24
E)w1=-3.62 w2=-2.74
14.calculate △E(KJ)between state B and state A
A)2.53 B)-1.52 C)-2.53 D)1.52 E) -3.04
......终於打完了......
