6 Tusaalooyin su'aalo ah oo ku saabsan ku dhaqanka sharciga koowaad ee thermodynamics ee hababka isobaric (cadaadis joogto ah)
1. Cadaadiska (P) - garaafka mugga (V) ee gaaska oo maraya habka isobaric. Shaqada uu gaaska ku sameeyo habka AB waa…
Dood
Waa la garanayaa :
Cadaadiska (P) = 5 x 105 N / m2
Mugga bilowga ah (V)1) = 2 m3
Mugga kama dambaysta ah (V)2) = 6 m3
La weydiiyay : shaqada lagu qabtay habka AB
Jawab :
W = P (V)2 - V1)
W = (5 x 105)(6 – 2) = (5 x 105) (4)
W = 20 x 105 = 2x106 Joule
2. Farqiga shaqada uu gaaska ku sameeyo hababka AB iyo CD waa…
Dood
Waa la garanayaa :
Habka isobaric AB :
Cadaadiska (P) = 6 atm = 6 x 105 N / m2
Mugga bilowga ah (V)1) = 1 litir = 1 dm3 = 1x10-3 m3
Mugga kama dambaysta ah (V)2) = 3 litir = 3 dm3 = 3x10-3 m3
Habka isobaric CD-ga :
Cadaadiska (P) = 4 atm = 4 x 105 N / m2
Mugga bilowga ah (V)1) = 2 litir = 2 dm3 = 2x10-3 m3
Mugga kama dambaysta ah (V)2) = 5 litir = 5 dm3 = 5x10-3 m3
La weydiiyay Kala duwanaanshaha shaqada uu gaaska sameeyo ee hababka AB iyo CD
Jawab :
Shaqada uu gaaska ku sameeyo AB-ga:
W = P (V)2 - V1)
W = (6 x 105)(3 x 10-3 - 1 x 10-3)
W = (6 x 105)(2 x 10-3)
W = 12 x 102 = 1200 Joule
Shaqada uu gaaska ku sameeyo habka CD-ga:
W = P (V)2 - V1)
W = (4 x 105)(5 x 10-3 - 2 x 10-3)
W = (4 x 105)(3 x 10-3)
W = 12 x 102 = 1200 Joule
Farqiga shaqada uu gaaska ku sameeyo hababka AB iyo CD waa 1200 - 1200 = 0.
3. Shaqada uu gaaska ku qabtay habka ABC waa…
Dood
Waa la garanayaa :
Cadaadiska 1 (P)1) = 6 x 105 Pascal = 6 x 105 N / m2
Cadaadiska 2 (P)2) = 3 x 105 Pascal = 3 x 105 N / m2
Mugga 1aad (V)1) = 2cm3 = 2x10-6 m3
Mugga 2aad (V)2) = 6cm3 = 6x10-6 m3
La weydiiyay Dadaallada lagu sameeyay habka ABC.
Jawab :
Habka AB, mugga waa mid joogto ah, sidaa darteed ma jiro wax shaqo ah oo uu gaasku qabto. Gaasku wuxuu shaqeeyaa oo keliya habka BC. Markaa shaqada ABC = shaqada ku jirta habka BC.
W = P2 (V2 - V1)
W = (3 x 105)(6 x 10-6 - 2 x 10-6)
W = (3 x 105)(4 x 10-6)
W = 12 x 10-1
W = 1,2 Joule
Shaqada lagu sameeyay habka ABC = 1,2 Joules.
4. Hadalka saxda ah ee ku saabsan hababka thermodynamic waa…
A. Isobaric waa habka lagu beddelo gaaska cadaadis joogto ah.
B. Isobaric waa habka lagu beddelo gaaska heerkul joogto ah.
C. Isochoric waa hab lagu beddelo gaaska cadaadis joogto ah.
D. isotherm waa habka lagu beddelo gaaska mugga joogtada ah.
E. Isochoric waa hab lagu beddelo gaaska heerkul joogto ah.
Dood
Isobaric = cadaadis joogto ah
Isochoric = mug joogto ah
Isothermal = heerkul joogto ah
Jawaabta saxda ah waa A.
5. Isbarbardhigga dadaallada geeddi-socodka I iyo II iyadoo lagu saleynayo garaafka hoose waa...
A. 4: 3
B. 3: 4
C. 2: 3
D. 1: 2
E. 1: 3
Dood:
Waa la garanayaa :
Geedi socodka I: P = 15 N/m2, V1 = 15 m3, V2 = 35 m3
Geedi socodka II: P = 10 N/m2, V1 = 5 m3, V2 = 45 m3
La weydiiyay :
Isbarbardhigga dadaalka (W) ee habka I iyo habka II?
Jawab :
Jawaabta saxda ah waa B.
6. Jaantuska PV ee gaaska helium ee maraya habka thermodynamic waxaa lagu muujiyay sawirka hoose! Shaqada uu qabtay gaaska helium ee habka ABC waa…
A. 400 kJ
B. 500 kJ
C. 600 kJ
D. 800 kJ
E. 1000 kJ
Dood:
Waa la garanayaa :
P1 = 2x105 N / m2
P2 = 1x105 N / m2
V1 = 5 m3
V2 = 15 m3
La weydiiyay :
Shaqada (W) ee habka ABC?
Jawab :
Shaqada waxaa la qabtaa oo keliya marka mugga gaaska uu kordho. Habka AB, mugga gaaska wuxuu ahaanayaa mid joogto ah, sidaa darteed wax shaqo ah laguma qabto gaaska helium. Habka BC, mugga gaaska wuu kordhaa, sidaas darteed shaqada waxaa qabta gaaska helium.
