Kutheni usebenzisa Celsius?

Kule mihla, akunakwenzeka ukuba ukuphila ngaphandle imilinganiselo. Umlinganiselo ubude, umthamo, ubunzima kunye nobushushu. Kukho iiyunithi eziliqela onke amanyathelo, kodwa zikhona
ezaziwayo. Zisetyenziswa phantse kuyo yonke indawo. Kuba ubushushu womlinganiselo kwi-International System of Units Celsius usetyenziswa kakhulu lula. Kuphela US kunye UK zisekhona echanekileyo ngaphantsi Fahrenheit.

Imbali lobushushu yokulinganisa

Ingcamango lobushushu liye makwazeke kubantu ukususela kumaxesha amandulo. Baya owayenokugqiba ukuba into ufudumele okanye ebandayo ngaphezu enye. Kodwa iimfuno yomlinganiselo echanekileyo akazange kuvela kude kube lelo xesha njengoko kwakungekho imveliso. Insimbi, oomatshini umphunga ayikwazanga ukusebenza ngaphandle isidanga ngqo operedeleniya izinto ezishushu. Ngoko ke, oososayensi baqalisa ukusebenza ngokudala iindlela lobushushu womlinganiselo.

Inkqubo yokuqala onjalo owaziwayo Fahrenheit. yamachiza German Gabriel qhwa ngo-1724, wacela ukuba ukuthatha phezu 0 izidanga lobushushu ukunyibilika umxube lomkhenkce netyuwa. Ngokutsho isikali yethu ithi malunga -21 ^o. Kule ¹⁰⁰ sisazinzulu wathembisa ukuba iqondo lobushushu eqhelekileyo umzimba womntu. Le nkqubo azicacanga kakhulu, kodwa isasetyenziswa nangoku eUnited States, kuba iqabaka eyomeleleyo degrees 21 ukuba azenzeki.

Yintoni enye isikali lobushushu

17-18 leminyaka th - ixesha nasekuphuhliseni inzululwazi nobugcisa. Izazinzulu abaninzi baye bazama ukwenza eyakho isikali lwabo lobushushu. Xa ukuphela kwabo sele likhona ngenkulungwane ye-18 malunga 20. Kodwa kuphela abambalwa baye kusetyenziswa.

Reaumur isikali

yamachiza Frantsuzskiyy Rene Antuan de Reaumur Fersho ecetywayo ukusetyenziswa ithemomitha utywala. Ngowe-1730, wathabatha njengesiqalo ^ka-0, qhwa amanzi. Kodwa ke ubushushu abilayo for 80 Wathabatha ^on. Eneneni, xa utshintsho kobushushu nge-1 ^of isisombululo ezinxilisayo leyo awasebenzisa ithemometha yatshintshwa kwi-1 ml. kwaba
ungakhululekanga, nangona oku uluhlu waphila ixesha elide eFransi eRashiya.

isikali Celsius

Naye ecetywayo ngo 1742 yi-nzulu Swedish Anders Tselsy. Isikali lobushushu yayahlulwe 100 ^ukuya phakathi qhwa amanzi abilayo. Celsius - nangoku iyunithi ixhaphakileyo lobushushu womlinganiselo ehlabathini lonke.

Kelvin isikali

Ngenkulungwane ye-19 kunye nophuhliso obizwa kwavela imfuneko isikali lula ukuba ubalo ukwenzela ukuba unxulumanise nengcinezelo, umthamo kunye nobushushu le zomphunga. yamachiza IsiNgesi Thompson, ngubani ogama emva kokuba iNkosi Kelvin wacebisa njengesiqalo ukuqwalasela zero epheleleyo. Celsius zisetyenziswe ngengomlinganiselo ezi ezikalini ezimbini, zisekhona kunye.

Njani isikali Celsius

sesayensi yaphakanyiswa ukuba 0 ^ukuqwalasela iqondo yamanzi, a qhwa of - 100 ^o. Kude kube ngoku, sisebenzisa ukulinganisa degrees Celsius, nangona ingcamango abenaso Carlo Renaldini. Yaba nguye lowo wacebisa ukusetyenziswa kwamanzi abilayo kunye qhwa amanzi kwasekuqaleni 1694.

Ithemometha yokuqala ngokusekelwe ngezimvo Celsius wasetyenziswa Carl Linnaeus ngo-1744 ukuya iliso izityalo. Daniel Ekstrom wakudala, igalelo elikhulu ekuziseni isikali engqondweni wenza nzulu mihla Martin Shtremer. Yaba ubushushu lokuqala 0 degrees Celsius wabonisa qhwa yamanzi, kwaye ^malunga ne-100 - abilayo yayo.

Le nkqubo yaba lula kakhulu kwaye kwafikela ehlabathini lonke. Noko ke, ekuqaleni yayibizwa "isikali Extrema" okanye "isikali Shtremer". Kwaye kuphela ngo-1948 kwathiwa ngokomthetho, ogama emva Celsius kwaye wavuma ehlabathini lonke.

Celsius application

Ngoku phantse onke amazwe basebenzisa le nkqubo ezithile lobushushu womlinganiselo. Emva qhwa amanzi iyafana kuzo zonke iimbombo zomhlaba kwaye akuxhomekekanga xi. Namanzi akuphela kwento eyona ininzi emhlabeni. Ngoko ke ngoku wonke umntwana eyaziwa izidanga uphawu Celsius.
