6 Mienzaniso yemibvunzo pamusoro pekushandiswa kwemutemo wekutanga wethermodynamics kune maitiro e-isobaric (kumanikidzwa nguva dzose)
1. Kumanikidzwa (P) – girafu yevhoriyamu (V) yegesi riri kuita isobaric process. Basa rinoitwa negesi riri muprocess AB…
Kukurukurirana
Zvinozivikanwa :
Kumanikidzwa (P) = 5 x 105 N / m2
Vhoriyamu yekutanga (V)1) = 2 m3
Vhoriyamu yekupedzisira (V)2) = 6 m3
Akabvunzwa : basa rakaitwa mukuita AB
Jawab :
W = P (V)2 - V1)
W = (5 x 10)5)(6 – 2) = (5 x 105(4)
W = 20 x 105 = 2 x gumi6 Joule

Maitiro eIsobaric AB :
Kumanikidzwa (P) = 6 atm = 6 x 105 N / m2
Vhoriyamu yekutanga (V)1) = marita gumi = 1 dm3 = 1 x gumi-3 m3
Vhoriyamu yekupedzisira (V)2) = marita gumi = 3 dm3 = 3 x gumi-3 m3
Maitiro eCD isobaric :
Kumanikidzwa (P) = 4 atm = 4 x 105 N / m2
Vhoriyamu yekutanga (V)1) = marita gumi = 2 dm3 = 2 x gumi-3 m3
Vhoriyamu yekupedzisira (V)2) = marita gumi = 5 dm3 = 5 x gumi-3 m3
Akabvunzwa Musiyano mubasa rinoitwa negasi mumabasa AB neCD
Jawab :
Basa rinoitwa negasi riri muchikamu cheAB:
W = P (V)2 - V1)
W = (6 x 10)5)(3 x 10-3 - 1 x 10-3)
W = (6 x 10)5)(2 x 10-3)
W = 12 x 102 = 1200 Joule
Basa rinoitwa negasi muCD process:
W = P (V)2 - V1)
W = (4 x 10)5)(5 x 10-3 - 2 x 10-3)
W = (4 x 10)5)(3 x 10-3)
W = 12 x 102 = 1200 Joule
Musiyano mubasa rinoitwa negasi mumaitiro eAB neCD i1200 - 1200 = 0.
3. Basa rinoitwa negasi muABC process nderiri…
Kukurukurirana
Zvinozivikanwa :
Kumanikidzwa 1 (P)1) = 6 x 105 Pascal = 6 x 105 N / m2
Kumanikidzwa 2 (P)2) = 3 x 105 Pascal = 3 x 105 N / m2
Vhoriyamu 1 (V)1) = 2 cm3 = 2 x gumi-6 m3
Vhoriyamu 2 (V)2) = 6 cm3 = 6 x gumi-6 m3
Akabvunzwa : Kuedza kwakaitwa mukuita kweABC.
Jawab :
Mukuita AB, vhoriyamu haichinji, saka hapana basa rinoitwa negasi. Gasi rinoshanda chete mukuita BC. Saka basa riri mukuita ABC = basa riri mukuita BC.
W = P2 (V2 - V1)
W = (3 x 10)5)(6 x 10-6 - 2 x 10-6)
W = (3 x 10)5)(4 x 10-6)
W = 12 x 10-1
W = 1,2 Joule
Basa rakaitwa muABC process = 1,2 Joules.
4. Chirevo chakarurama nezvemaitiro ethermodynamic ndechekuti…
A. Isobaric inzira yekuchinja gasi padanho rinogara richimanikidzwa.
B. Isobaric inzira yekushandura gasi patembiricha yakaenzana.
C. Isochoric inzira yekuchinja gasi padanho risingaperi.
D. isotherm inzira yekushandura gasi pahuwandu husingachinji.
E. Isochoric inzira yekushandura gasi patembiricha yakaenzana.
Kukurukurirana
Isobaric = kumanikidzwa nguva dzose
Isochoric = vhoriyamu isingachinji
Isothermal = tembiricha isingachinji
Mhinduro chaiyo ndiA.
5. Kuenzanisa kwemabasa ari kuitwa mumabasa ekutanga neachipiri zvichibva pagirafu iri pazasi ndiko...
A. 4: 3
B. 3: 4
C. 2 : 3
D. 1: 2
Chikamu 1: 3
Kukurukurirana:
Zvinozivikanwa :
Maitiro I: P = 15 N/m2, V1 = 15 XNUMX m3, V2 = 35 XNUMX m3
Maitiro II: P = 10 N/m2, V1 = 5 m3, V2 = 45 XNUMX m3
Akabvunzwa :
Kuenzanisa kushanda nesimba (W) kwemaitiro I uye maitiro II?
Jawab :
Mhinduro chaiyo ndeiyi B.
6. Dhayagiramu yePV yegesi rehelium riri kuitwa muchimiro chethermodynamic inoratidzwa mumufananidzo uri pazasi! Basa rinoitwa negesi rehelium mukuita ABC…

B. 500 kJ
C. 600 kJ
D. 800 kJ
E. 1000 kJ
Kukurukurirana:
Zvinozivikanwa :
P1 = 2 x gumi5 N / m2
P2 = 1 x gumi5 N / m2
V1 = 5 m3
V2 = 15 m3
Akabvunzwa :
Basa (W) muABC process?
Jawab :
Basa rinoitwa chete kana huwandu hwegasi hwawedzera. Mukuita AB, huwandu hwegasi hunoramba hwakafanana, saka hapana basa rinoitwa negasi rehelium. Mukuita BC, huwandu hwegasi hunowedzera, saka basa rinoitwa negasi rehelium.
