Ngokwalokhu okucashunwe lapha, nquma ukuthi ubani owasungula incazelo yokuqala ye - thermodynamics nokuthi yayenziwe nini.
Context:Ngokomlando, i-thermodynamics yasungulwa ngenxa yesifiso sokwandisa ukusebenza kahle kwezinjini zokuqala zensimbi, ikakhulukazi ngomsebenzi wesayensi yaseFrance uSadi Carnot (1824) owayekholelwa ukuthi ukusebenza kahle kwenjini kwakuyisihluthulelo esasiza iFrance ukunqoba izimpi zikaNapoleon. Isazi sesayensi yemvelo saseScotland-Irish uLord Kelvin waba ngowokuqala ukuveza incazelo emfushane ye-thermodynamics ngo-1854 eyayithi, "I-thermodynamics iyisihloko sobudlelwano bokushisa namandla asebenza phakathi kwezingxenye ezihlangene zemizimba, kanye nobudlelwano bokushisa nomenzeli kagesi". Isazi sezibalo nesiJalimane uRudolf Clausius saphinda sachaza isimiso sikaCarnot esaziwa ngokuthi umjikelezo kaCarnot futhi kanjalo sanikeza inkolelo-mbono yokushisa isisekelo esiyiqiniso nesinengqondo. Iphepha lakhe elibaluleke kakhulu elithi "On the Moving Force of Heat", elanyatheliswa ngo - 1850, labeka umthetho wesibili we - thermodynamics. Ngo-1865 wethula umqondo we - entropy. Ngo-1870 wethula isimiso se-virial, esasisebenza ekushiseni.
