18.令符號h = 焓，Cp = 定壓比熱，Cv = 定容比熱，k = 比熱比（Cp /Cv），T = 溫度，則自狀態1變 化至狀態2之焓變化量h2 – h1為何？
(A).h2 – h1 = k (T2 – T1 )
(B).h2 – h1 = (T2 – T1 ) /k
(C).h2 – h1 =Cv (T2 – T1 )
(D). h2 – h1 =Cp (T2 – T1 )
(A).h2 – h1 = k (T2 – T1 )
(B).h2 – h1 = (T2 – T1 ) /k
(C).h2 – h1 =Cv (T2 – T1 )
(D). h2 – h1 =Cp (T2 – T1 )
