Ukuqonda Izinga Lokushisa Nokushisa
Izinga lokushisa . Umqondo wokushisa empeleni uvela ekuzweni kokushisa nokubanda okubonwa umuzwa wethu wokuthinta. Ngokusekelwe kulokho umuzwa wethu wokuthinta okuzwakalayo, sithi into ishisa kakhulu kunenye into noma into ibanda kakhulu kunenye into. Izinto ezishisayo zinezinga lokushisa eliphakeme kuyilapho izinto ezibandayo zinezinga lokushisa eliphansi. Uma into ibanda kakhulu, izinga lokushisa layo liphansi. Ngokuphambene nalokho, uma into ishisa kakhulu, izinga lokushisa layo liphakeme. Lesi silinganiso sokushisa noma ukubanda kwento sibizwa ngokuthi izinga lokushisa. Esihlokweni se-kinetic theory yamagesi esizofundwa kamuva ebangeni le-11, uzoqonda ngokujulile incazelo yokushisa; kwenzekani kuma-molecule akha into leyo into engayizwa ishisa, ifudumele, ipholile noma ibanda.
AmakhaloriUma izinto ezinamazinga okushisa ahlukene zithintana, kuzoba nokudluliselwa kokushisa, okuvame ukubizwa ngokuthi amandla okushisa, kusuka entweni enezinga lokushisa eliphezulu kuya entweni enezinga lokushisa eliphansi. Ukudluliselwa kokushisa Ukudluliselwa kokushisa kuyama uma izinto ezithintanayo zifinyelela izinga lokushisa elifanayo. Isibonelo, uma sixuba amanzi ashisayo namanzi abandayo, ukushisa kuvame ukuhamba kusuka emanzini ashisayo kuya emanzini abandayo. Uma sifaka insimbi eshisayo emanzini abandayo, ukushisa kuyahamba kusuka ensimbini eshisayo kuya emanzini. Ukudluliselwa kokushisa kuyama uma insimbi namanzi kufinyelela izinga lokushisa elifanayo. Uma udokotela noma umhlengikazi enamathisela i-thermometer emzimbeni wakho, ukushisa kuyama kusuka emzimbeni wakho kuya ku-thermometer. Ukudluliselwa kokushisa kuyama uma umzimba wakho ne-thermometer sekufinyelele izinga lokushisa elifanayo. Uma i-thermometer esetshenziswayo iyi-thermometer ye-mercury, lapho umzimba wakho ne-thermometer kufinyelela izinga lokushisa elifanayo, ubuso be-mercury buyama ukuhamba. Inombolo ekhonjisiwe ebusweni be-mercury izinga lokushisa lomzimba wakho ngaleso sikhathi.
Ngokwemvelo, ukushisa ngokwemvelo kuhamba kusuka ezintweni ezinokushisa okuphezulu kuya ezintweni ezinokushisa okuphansi. Ukudluliselwa kokushisa kuvame ukulinganisa amazinga okushisa ezinto ezithintanayo. Ngekhulu le-18, izazi zefiziksi zazisola ukuthi ukugeleza kokushisa kwakuwukuhamba koketshezi, uhlobo olungabonakali loketshezi (uketshezi luyizinto ezingageleza. Uketshezi luhlanganisa uketshezi namagesi. Amanzi (uketshezi) luwuketshezi ngoba lungageleza. Umoya nawo uketshezi ngoba lungageleza). Lolu ketshezi lubizwa ngokuthi ci-aloric. Imibono mayelana ci-aloric ayisasetshenziswa ngoba ngokusekelwe emiphumeleni yokuhlolwa, ukuba khona ikhalori Lokhu akunakufakazelwa. Ngekhulu le-19, isazi sesayensi yefiziksi saseNgilandi okuthiwa uJames Prescott Joule (1818-1889) safunda indlela yokushisa amanzi esitsheni sisebenzisa isondo lokushukumisa futhi saqhathanisa ukufudumala kwamanzi ngenxa yokujikeleza kwesondo lokushukumisa nokufudumala kwamanzi esitsheni esithintwe ilangabi noma umthombo kagesi. Ngokusekelwe ekuhlolweni kwakhe, uJoule waphetha ngokuthi Ukushisa akuwona amandla (ukushisa akulona uhlobo oluthile lwamandla, njengamandla e-kinetic, amandla angase abe khona, amandla amakhemikhali, njll.). Ukushisa kungamandla adluliselwa ngenxa yokwehluka kwezinga lokushisa. Ngakho-ke lapho ukushisa kugeleza kusuka entweni enokushisa okuphezulu kuya entweni enokushisa okuphansi, amandla empeleni adluliselwa kusuka entweni enokushisa okuphezulu kuya entweni enokushisa okuphansi. Lokhu kudluliswa kwamandla kuyama uma izinto ezithintanayo zifinyelela izinga lokushisa elifanayo, noma ukulingana kokushisa.
