Question

Am nevoie urgent .Va rog

Answer 1

1-4-5, L=L1-4+L4-5=0+L4-5=niu

RT1In V5/V1=p1V1In V5/V1=0,2×106×2×10-3×0,4=0,4×0,4×1000=160J

L şi Q sunt mărimi de proces, dar UK este mărime de stare U1-5=niu Cv (T5-T1)

Q=Q14+Q4-5=niu Cv(T4-T1)+niu

Cp(T5-T4)=-niu 3/2R×200+niu 5/2

R×100=niu R×50(-6+5)=-p1V1/T1×50=0,2×2×10-3×50/400

p1/T1=p4/T4, p4=p5, T4=p5T1/p1=0,1/0,2×400=200K

pt gaze monoatomic Cv=3/2 R, Cp=5/2 R
