5 tusaale oo ku saabsan ku dhaqanka sharciga koowaad ee thermodynamics hababka isothermal-ka (heerkulka joogtada ah)

1. Jaantuska hoose wuxuu muujinayaa gaas ku habboon oo la marinayo Habka isothermal-ka (habka). Shaqada uu gaaska ku qabto habka AB waa…
Tusaale ahaan ku dhaqanka sharciga koowaad ee thermodynamics habka isothermal-ka ee heerkulka joogtada ah 1Dood
Shaqada la qabtay = bedka ka hooseeya qalooca AB = bedka saddexagalka + bedka leydiga
W = [½ (8 x 105–4 x 105)(3-1)] + [4 x 105 (3-1)]
W = [½ (4 x 105)(2)] + [4 x 105 (2)
W = [4 x 105] + [8 x 105]
W = 12 x 105 Joule
Shaqada uu gaaska ku sameeyay habka AB = 12 x 105 Joule

2. Shaqada uu qabto gaaska ku habboon ee ABC waa…
Tusaale ahaan ku dhaqanka sharciga koowaad ee thermodynamics habka isothermal-ka ee heerkulka joogtada ah 3Dood
Waa la garanayaa :
Cadaadiska 1 (P)1) = 10 x 105 N / m2
Cadaadiska 1 (P)1) = 5 x 105 N / m2
Mugga 1aad (V)1) = 10 litir = 10 dm3 = 10x10-3 m3
Mugga 2aad (V)2) = 30 litir = 30 dm3 = 30 x 10-3 m3
La weydiiyay Shaqada uu gaaska ku qabto ABC
Jawab :
Marka la eego habka BC, mugga wuxuu ahaanayaa mid joogto ah, sidaa darteed ma jiro shaqo uu gaasku qabto. Gaasku wuxuu shaqeeyaa oo keliya habka AB sababtoo ah waxaa jira isbeddel ku yimaada mugga. Sidaa darteed, shaqada uu gaasku qabto ee habka ABC = shaqada uu gaasku qabto ee habka AB.
Shaqada uu qabto gaaska = aagga ka hooseeya qalooca AB = bedka saddexagalka + bedka leydiga.
W = [½(10×10)5–5×105)(30-10)]+[5×105(30-10)]
W = [½ (5 x 105)(20)] + [5 x 105 (20)
W = [(5 x 105)(10)] + [100 x 105]
W = [50 x 105]+ [100 x 105]
W = 150 x 105 Joule
W = 1,5 x 107 Joule

3. Gaasku wuxuu maraa hab-raac isothermal ah. Xaddiga kulaylka ee ay tahay in la nuugo si gaaska uu u qabto 5000 Joules oo shaqo ah waa…
Dood
Waa la garanayaa :
Shaqada (W) = 5000 Joules
La weydiiyay Kuleylka oo la nuugo (Q)
Jawab :
Habka isothermal-ka ee lagu sheegay su'aashan waa habka thermodynamic kaas oo heerkulku uu yahay mid joogto ah. Xiriirka ka dhexeeya heerkulka (T) iyo isbeddelka tamarta gudaha ee gaaska waxaa lagu muujiyaa isla'egta soo socota:
Tusaale ahaan ku dabaqidda sharciga koowaad ee thermodynamics habka isothermal-ka (heerkulka joogtada ah) - 3Haddii heerkulku joogto yahay, markaas isbeddelka heerkulku waa eber. Isbeddelka heerkulku waa eber, sidaas darteed, isbeddelka tamarta gudaha waa eber. Ku dhaqanka sharciga koowaad ee thermodynamics wuxuu keenaa natiijooyinka soo socda.
Sharciga ugu horreeya ee thermodynamics :
Tusaale ahaan ku dabaqidda sharciga koowaad ee thermodynamics habka isothermal-ka (heerkulka joogtada ah) - 4Haddii isbeddelka tamarta gudaha (U) uu eber yahay, markaas kulaylka (Q) ee gaaska nuugaya wuxuu la mid yahay shaqada uu gaaska (W) qabto. Marka gaasku nuugo kulaylka, gaasku wuxuu helaa tamar dheeraad ah, tamartan dheeraadka ahna waxaa gaaska u isticmaala shaqada.
Markaa kulaylka uu nuugo gaaska = shaqada uu sameeyo gaaska = 5000 Joules.

4. Garaafka cadaadiska (P) ee ka dhanka ah mugga (V) ee gaaska maraya habka isothermal-ka ayaa lagu muujiyay sawirka hoose. Qadarka kulaylka uu nuugo gaaska habka AB waa…

Tusaale ahaan ku dabaqidda sharciga koowaad ee thermodynamics habka isothermal-ka (heerkulka joogtada ah) - 5Dood
Waa la garanayaa :
Cadaadiska 1 (P)1) = 5 atm = 5 x 105 Pa
Cadaadiska 2 (P)2) = 10 atm = 10 x 105 Pa
Mugga 1aad (V)1) = 2 m3
Mugga 2aad (V)2) = 6 m3
La weydiiyay Kuleylka (Q) ee uu nuugo gaaska ku jira habka AB
Jawab :
Isothermal = heerkul joogto ah. Haddii heerkulku uu ahaado mid joogto ah, isbeddelka heerkulku waa eber. Haddii isbeddelka heerkulku yahay eber, isbeddelka tamarta gudaha waa eber. Xiriirka ka dhexeeya isbeddelka heerkulka iyo isbeddelka tamarta gudaha ee gaaska waxaa lagu muujiyaa isla'egta soo socota:
Tusaale ahaan ku dabaqidda sharciga koowaad ee thermodynamics habka isothermal-ka (heerkulka joogtada ah) - 6Haddii lagu dabaqo sharciga koowaad ee thermodynamics, natiijooyinka soo socda ayaa la helaa:
Tusaale ahaan ku dabaqidda sharciga koowaad ee thermodynamics habka isothermal-ka (heerkulka joogtada ah) - 7Haddii isbeddelka heerkulku eber yahay, markaa kulaylka uu nuugo gaaska wuxuu la mid yahay shaqada uu sameeyo gaaska. Si loo helo kulaylka uu nuugo gaaska habka AB, waxaan xisaabineynaa shaqada uu sameeyo gaaska iyadoo lagu saleynayo garaafka kore.
Shaqada uu qabto gaaska = aagga ka hooseeya qalooca AB = bedka saddexagalka + bedka leydiga.
W = ½ (P)2 - P1)(V2 - V1) + P1(V2 - V1)
W = ½ (10 x 105 - 5 x 105)(6-2) + (5 x 10)5)(6-2)
W = ½ (5 x 105)(4) + (5 x 10)5) (4)
W = ½ (20 x 105) + (20 x 105)
W = (10 x 105) + (20 x 105)
W = 30 x 105 Joule
W = 30 atm
Kulaylka (Q) ee uu nuugo gaaska habka AB = shaqada uu qabto gaaska habka AB = 30 x 105 Joule = 30 jawi.

D. ku saabsan heerkulka xawaaraha molecular-ka oo sarreeya
E. cadaadiska iyo mugga gaaska isma beddelaan

Dood
