Ukushisa ezithile Fusion - kungcono kakhulu

gaseous, uketshezi, okuqinile - Iqiniso lokuthi into kungenzeka omunye uthi owaziwa. Futhi ungaya komunye. Isibonelo elula - ucezu ice liyancibilika, liquefies, bese ngababili. Kuyo yonke le nqubo ukuguqulwa esiqinile ukuze isigaba umusi kuyinto ukuncibilika ezithakazelisa kakhulu futhi omunye imingcele yayo - ukushisa ezithile ukuncibilika.

Ngezinye umuzwa wethu uthi iyiphi into kungenziwa bhotela. Lokhu futhi kufakazelwa wonke umlando impucuko. Kuvulwa impahla ukuncibilika wayengomunye walaba ezisunguliwe enkulu ekutfutfukiseni bantfu. Kodwa encibilika - akuyona inqubo lula. Uma uyibambe khona imibuzo eminingi, futhi omunye wabo imayelana kangakanani udinga amalahle (Peat, ukhuni, igesi) zigcwale amanzi ucezu yensimbi noma ithusi. Futhi lapha aphinde kumelwe ubheke nomqondo "ukushisa esicashile ka ukuncibilika."

Uma sikhumbula ukuthi ukuncibilika, kungenzeka ukuhlukanisa izigaba eziningana. Thatha isibonelo phambili. Ngesikhathi esigabeni sokuqala Ukushisa phambili, izinga lokushisa likhuphuka ukuba 327 ° C (ukuncibilika lokushisa). Ngemva ukuncibilika uqalile, akwenzeki lutho isikhathi eside.

phambili okuphansi, naphezu ukushisa enikeziwe kuso, kugcinwa njalo futhi lokhu kuze kube sekupheleni lonke inqubo. Futhi kuphela emva kwalokho nge baqhubeka Ukushisa lokushisa liqala ukuphakama futhi. Kusukela iphethini waphawula kulandele ezinye iziphetho. Enkulumweni okuqinile, wonke ama-molecule kukhona ngendlela ethile futhi isandla exhunywe ne amangqamuzana engumakhelwane.

Ukuze bakwazi ukuhambisa ngokukhululekile kwenye indawo, ngokuqondene molecule angomakhelwane kubalulekile ukuba aphule, okwenzeka enqubeni ukuncibilika. Ukuze wenze lokhu, umzimba kungase kudingeke badlule ngesilinganiso esithile ukushisa, ngokuthi ngesikhathi sokushisa kwemini Fusion. Ukuze izidakamizwa ngamunye, zidinga amanani angalingani ukushisa. Isizathu kungenxa lokhu impahla ndaba njengoba ukushisa ezithile ukuncibilika, okuyinto ichazwa inani ukushisa kuthatha zigcwale amanzi eyodwa kilogram ka ndaba. Lesi simiso Joule / kilogram.

Njengoba sekushiwo, izinto ngayinye lesi silinganiso kuyinto evamile. ukushisa Specific lomthofu ihlukile ukuncibilika ubuningi efanayo ice. Lokhu kuphakamisa iphuzu ezithakazelisayo kakhulu. Ukushisa ezithile encibilika le steel yisilinganiso sesifundo 85 kJ / kg, futhi amanzi (ice), ipharamitha efanayo yisilinganiso sesifundo 335 kJ / kg. Ngo ice kwenani le ipharamitha angabhekwa njengesipho omkhulu emvelweni.

Phela, sibonga bonke iqhwa, iqhwa akusho ancibilike kweso, futhi konke kwenzeka ukuba kube isikhathi eside. Kungenjalo, iqhwa ngabe ancibilike ngokushesha okukhulu, kanti izikhukhula ayelapho kungaba omningi kakhulu futhi elimazayo. Ngaphezu kwalokho, izakhiwo ezifana esiyingqayizivele yamanzi neqhaza kuqiniswa sezulu emhlabeni.

Kukhona amatafula idatha ukushisa ezithile ukuncibilika izinto ezikhethiwe. Ukwazi lesi silinganiso, kulinganiselwa kanjani ukushisa kakhulu kuyadingeka ukuze ancibilike impahla kanye thola ukuthi kungakanani udinga yokubasela yokuncibilikisa ithusi. Uma umzimba ufakwa sishisiswe izinga lokushisa ukuncibilika, ukushisa idingeka kuphela ukuncibilika, futhi uma izinga lokushisa lingaphansi lokushisa ukuncibilika, ukushisa adingekayo amalahle kwento ukuncibilika lokushisa.

izibalo ezinjengalezi ziwusizo umkhakha kakhulu ukubala izindleko zokukhiqiza.

Phela, ngesikhathi Ukupholisa sendaba oncibilikisiwe siyachithwa inqubo ukuncibilika - crystallization. Kulokhu, ngesikhathi ketshezi ukupholisa walulama izibopho ezaphulwa phakathi molecule uphehla ukushisa.

Uma ucabangela izinto ukuncibilika inqubo wedlula mkhuba lapho, umqondo ezifana ukushisa Fusion wayezimisele. Ukuqhathanisa lokhu Inkomba izinto ezihlukahlukene, kunqunywa okusezingeni eliphezulu kanjani ukubaluleka kwalesi ipharamitha at ice Kusizuzisa phezu kwesimo sezulu.
