Ukulinganiswa kwe-thermometer inqubo yokudala isikali ku-thermometer. Nazi ezinye izinyathelo zokulinganisa i -thermometer . Okokuqala , lungiselela i-thermometer ye-mercury noma i-thermometer yotshwala ngaphandle kwesikali. Okwesibili , lungiselela iqhwa elanele. Okwesithathu , lungiselela amanzi anele. Okwesine , lungiselela isifudumezi samanzi esingasetshenziswa ukushisa amanzi aze abilise. Okwesihlanu , faka iqhwa namanzi esitsheni (amanzi neqhwa anobunzima obufanayo). Ngemuva kwalokho, faka i-thermometer esitsheni esiqukethe amanzi neqhwa.
Ekuqaleni, i-thermometer ithinta umoya, okwenza kube kushisa kakhulu kuneqhwa. Ngemva kokufakwa esitsheni, ubude bekholomu ye-mercury buzoncipha ngoba ingxube yamanzi neqhwa ibanda kakhulu. Vumela ubude bekholomu ye-mercury buhlale bungashintshi (indawo engaphezulu ye-mercury ayinyakazi). Uma ubude bekholomu ye-mercury buhlala bungashintshi, ingxube yama-ice cubes namanzi ifinyelele izinga lokushisa eliphezulu. ukulingana kokushisaMaka indawo yekholomu ye-mercury (maka phezulu kwekholomu ye-mercury). Lokhu izinga lokushisa lamanzi eliba yizinga lokubanda.
Okwesithupha , bilisa amanzi usebenzisa isifudumezi sikagesi noma isitofu J. Faka i-thermometer esitsheni esinamanzi afudunyezwayo. Njengoba amanzi eshisa kakhulu noma izinga lokushisa lamanzi likhuphuka, ubude bekholomu ye-mercury buyanda (ubuso be-mercury buyakhuphuka). Ngemva kokuba amanzi ebila, ubuso obuphezulu be-mercury buyayeka ukuhamba. Maka ukuphela kwekholomu ye-mercury. Lokhu izinga lokushisa lephuzu lokubila lamanzi noma iphuzu lomusi.
Uma ufuna ukudala isikali se-Celsius, ibanga eliphakathi kwamamaki amabili lihlukaniswe ngemigqa eyi-100, lapho ibanga eliphakathi komugqa ngamunye kumele lifane. Uphawu olungezansi = 0o C, kanti uphawu oluphezulu = 100o C. Bheka isithombe ohlangothini.
Izinga lokushisa lendawo yokubanda kanye nephuzu lomhwamuko lincike ekucindezelweni komoya. Ngakho-ke, ama-thermometer alinganiswe ngezingcindezi zomoya ezahlukene azonikeza imiphumela ehlukene. Ama-thermometer e-mercury asetshenziswa kakhulu alinganiswe emoyeni owodwa, ngakho-ke izinga lokushisa lamanzi lingu-0 ° C kanti izinga lokushisa lokubila lingu-100 ° C.
Ama-thermometer ajwayelekile, njenge-mercury noma i-alcohol thermometer, avame ukulinganiselwa. Awakwazi ukusetshenziselwa ukukala amazinga okushisa aphansi kakhulu (ngaphansi kuka-0 ° C) noma amazinga okushisa aphezulu kakhulu (ngaphezu kuka-100 ° C).
