Inani ukushisa - akulula kanjalo

Uma beaker amanzi abilayo ushiye spoon abandayo ke ngemuva kwesikhathi esithile lokushisa yayo lilingana nezinga lokushisa elizosetshenziswa kule amanzi. Amanzi ayaphola phansi kancane, futhi spoon, kunalokho, uyabaselwa. Amazinga lapho kuba efanayo futhi kuziwa Equilibrium, ethile ukushisa adluliselwe ibavuthela emzimbeni ngaphansi kwezingaqhwa.

Ngokombono yamangqamuzana theory yesimanje kinetic yesifundvo kute lokushisa eliphezulu iphutha ukudluliselwa amandla ukuze into ezingeni lokushisa aphansi. Futhi inguquko esinjalo kwenzeka, lize lilingana lokushisa izindikimba ezimbili, okuyi bayofika esimweni yakhoibrium ezishisayo. Eqinisweni, umqondo nenani ukushisa, eyisilinganiso lokudluliselwa amandla, walondoloza kusukela lapho izazi zesayensi zisebenzisa i-eside ezifana caloric.

Nokho, lokhu akusho ukuthi ngeke sikwazi uholwe kubo namuhla. Lo mqondo kahle impela uchaza izinqubo ezenzeka ngesikhathi exchange ukushisa. Kuyinto ngokuvamile inani ukushisa ngencwadi Q futhi ulinganiswa Joules. Noma ngisho ukusebenzisa amayunithi akusebenzi yokukala - Calorie futhi (emikhulu) kilojoule. Manje, mhlawumbe, une touch kancane kuzokwenzekani indaba ekukhiqizeni amanye amandla avela ngaphandle.

Lapho ukudluliswa ukushisa wathola amandla (ukushisa) kungenziwa wachitha for amalahle ketshezi noma into (isipuni ingilazi), eshintsha isimo yayo wokuhlanganisa - encibilika (ibhotela epanini ukuthosa), noma ukuhwamuka (iketela ngesikhathi ipuleti). Ngokusobala, lokhu kuyinqubo ezahlukene, futhi ngayinye yemicimbi engenhla kuzodinga amandla akhe. Ososayensi baye ekugcineni wathola kungenzeka ukuba afeze ukubala inani ukushisa edingekayo ngamunye endabeni ethile.

Nokho, lapha futhi, kwakungelula njalo. Kuleso simo, uma isimo ndaba ayishintshi, amandla ewumphumela wakhona esisindo futhi lokushisa umehluko phakathi emizimbeni abasizanayo. Kufanele kuqondwe kusukela yilesi sibonelo esilandelayo. Uma ingilazi yamanzi abilayo ukubeka spoon ukukhanya ke spoon heats ngokushesha, futhi uma ukukhanyisa ingilazi yamanzi wagqoka ipuleti sesakhiwe abilayo, ushintsho ipuleti lokushisa kungatholakala kuphela ngokusebenzisa imishini ekhethekile.

Ngo ukwencika ngenhla kunakwe esinye isici - property ketshezi uqobo. Lokho okubizwa ngokuthi i - ipharamitha ekhethekile elisetshenziselwa ukuchaza izici ezibonakalayo kwama ukushisa ethize. Lokhu value limelela inani ukushisa okuyinto edingekayo ukuze uthumele ketshezi ukushintsha lokushisa yayo ngo-1 ° C. impahla ngayinye, lesi silinganiso esibonisa ikhono ukuthatha (ukunikeza) ukushisa bebodwa.

Uma e inqubo ukudluliswa ukushisa kushintsha isimo umzimba, okungukuthi, lincibilike bese ephenduka ibe umusi, bese ukhuluma okuncane mayelana nokuthi ezinye izinto. Ukuze Ncibilikisa impahla fed nalokho ngobungako ukushisa, ngokuthi ngesikhathi sokushisa kwemini Fusion, futhi isizukulwane umusi - nokuvutha vaporization.

Ngakho, esikhundleni othize ukushisa umthamo kulesi sibalo usebenzisa ukushisa esicashile Fusion noma vaporization. Ngenxa lezi zici zingatholakala inani ukushisa edingekayo ukuze kuncibilikiswe noma isisi Ukudluliselwa lemali oyifunayo lomcebo. Ngenxa yale njongo kubalulekile kuphela ukuze wande ukubaluleka ukushisa ezithile ukuncibilika noma vaporization Coefficient isisindo ketshezi. Lokho kuzodingeka lemali edingekayo ukushisa ukuthola umphumela oyifunayo (ukuncibilika noma vaporization). Izinto ongahlola ngazo kungaba kalula atholakala amareferensi.

Nakhu ukuthi ungakwazi ukuchaza kuyini inkolelo yokungafi inani ukushisa ngalo ihlobenenamanye, nalokho wachitha, futhi kanjani ukuze abone abuye abale elakhiwe (matasa) ukushisa at izinqubo ezahlukene ngokomzimba.
