Inqubo isobaric

inqubo Isobaric kuyinto izoprotsessa ukushintshashintsha okuyinto thermodynamic. Lapho nenqwaba therein impahla, futhi omunye imingcele yayo (ingcindezi, izinga lokushisa kanye ivolumu) zihlala zinjalo. Ukuze isobaric inqubo kontanga njalo.

inqubo Isobaric nomthetho Gay-Lussac

Ngo 1802, sibonga ukuqhuba uchungechunge ucwaningo, usosayensi French Joseph Louis Gay-Lussac alethwe njalo ukuthi ngomfutho njalo ivolumu ratio igesi lokushisa elinqunyiwe, nenqwaba ubuningi into okumele kube njalo. Ngamanye amazwi, ivolumu gas ithunzi elehlayo emazingeni alo ngesikhathi ingcindezi engapheli. Ezincwadini isiRashiya, umthetho umthetho Gay-Lussac, elibizwa nangokuthi amavolumu, futhi ngesiNgisi - umthetho Charles.

Ifomula ezaholela physics French ngaphansi inqubo isobaric kufanelekile ngokuphelele iyiphi igesi kanye nama-liquid umusi, lapho sekudlule emvuthwandaba.

isobar

Ngoba isithombe izinqubo ezinjalo kusetshenziswa samuntu sokuqhafaza isobar okuyinto umugqa oqondile ku mgudumbili Ukudidiyela uhlelo. Kukhona ama-ekseli amasondo amabili, enye yazo - ivolumu igesi, kuyilapho yesibili imelela ingcindezi. Nge ukwanda omunye izinkomba (lokushisa noma umthamo) ngokulingana uyanda futhi ebonisa wesibili ukuthi ihlinzeka umugqa oqondile njengoba schedule.

Izibonelo inqubo isobaric empilweni nsuku zonke Ukushisa amanzi embizeni ngaleso ipuleti, lapho umfutho womoya kuyinto njalo.

Isobar kungase ukuphuma iphuzu ngesikhathi Ukudidiyela izimbazo.

inqubo yomsebenzi igesi ngaphansi isobaric

Ngenxa yokuthi izinhlayiya igesi ziyahamba njalo, igesi ngokulandelana njalo ucindezela odongeni uyisitsha it is afakiwe. Njengoba izinga lokushisa kwandisa ezinyakazayo igesi izinhlayiya kuba ngokushesha futhi ke ngokuqina amandla ngawo izinhlayiya uqale ezibakhungathekisayo izindonga bomkhumbi. Uma izinga lokushisa iqala ukuba wehlise ke inqubo Kwenzeka okuphambene nalokho. Uma omunye izindonga bomkhumbi kuyinto ezithathekayo, ke elihambisana lokushisa efanele inyuka, - uma amandla ingcindezi gas kusuka ngaphakathi odongeni isitsha iba ephakeme ukwedlula amandla ukumelana, - udonga uqala ukunyakaza.

Ngo izingane zesikole ukuchaza lesi simo sibangelwa isibonelo Ukushisa ukushisa ingilazi isibani egcwele amanzi avalwa ngesivalo, lapho yokugcina lapho ukwanda lokushisa izimpukane kwangaphandle. Kulokhu, lo thisha njalo uthi ingcindezi ezenzeka kulo moya ozungeze njalo.

I Mechanics umzimba ukunyakaza kubhekwe maqondana Isikhala ezinyakazayo izifundo Thermodynamics izingxenye isihlobo umzimba komunye nomunye, lapho ijubane umzimba uhlala ilingane no-zero. Uma sikhuluma umsebenzi e wokushintsha kwamandla nokwakheka kwezinto, ke, okokuqala kunakho konke, siqonde ushintsho amandla angaphakathi, ngenkathi mechanical, sibhekene ushintsho energy kinetic. igesi Ukusebenza ngaphansi inqubo isobaric kungenziwa kunqunywa ifomula, lapho ingcindezi iphindwe umehluko phakathi amavolumu: kokuqala nokokugcina. Ephepheni, ifomula uzovela kanje: A = px (O1-O2), lapho A - enze umsebenzi, p - Pressure - ukubaluleka njalo uma imayelana inqubo isobaric, O1 - Umqulu wokugcina O2 - ivolumu kokuqala. Ngakho-ke, uma kukhona kokucindezelwa igesi, umsebenzi sizoba ukubaluleka ezimbi.

Ngenxa evulekile-Gay-Lussac ngasekuqaleni 19 igesi ekhulwini izakhiwo, singakwazi ukuqhubekela ku izimoto, lapho izimiso injini yokusebenza wabeka isobaric, ujabulele thunzi ukuthi ngosuku olushisayo sithola izinkulumo yesimanje air conditioning. Ngaphezu kwalokho, ukutadisha izinqubo isobaric kwenzekani namuhla, ezenza umsebenzi ngcono imishini esetshenziswa emkhakheni energy.
