Kusukela endimeni enikeziwe, khipha umkhawulo ophansi ngo-Celsius webanga lokushisa lekhofi elilungile.
Context:Izinhlamvu zekhofi kumelwe zigaywe bese zenziwa isiphuzo. Izindinganiso zokukhetha indlela zihlanganisa ukunambitheka nokonga. Cishe zonke izindlela zokulungiselela ikhofi zidinga ukuba ubhontshisi ugayiwe bese uxutshwa ngamanzi ashisayo isikhathi eside ngokwanele ukuba kuphume ukunambitheka kodwa hhayi isikhathi eside ngokwanele ukuba kukhishwe izinhlanganisela ezibabayo. Uketshezi lungadliwa ngemva kokususwa kwenhlabathi esetshenzisiwe. Izinto ezicatshangelwayo lapho kwenziwa ikhofi zihlanganisa ukugaya kahle, indlela amanzi asetshenziswa ngayo ukuze kukhishwe ukunambitheka, isilinganiso se-coffee grounds namanzi (isilinganiso sokuphisa), ukunambitheka okungeziwe njengoshukela, ubisi, nezinongo, kanye nendlela yokusebenzisa ukuze kuhlukaniswe i-grounds esetshenzisiwe. Ukukhishwa kwekhofi okuhle kakhulu kwenzeka phakathi kuka-91 no-96 °C (196 no-205 °F). Izinga lokushisa elifanele liphakathi kuka-85 kuya ku-88 °C (185 kuya ku-190 °F) kuze kufike ku-93 °C (199 °F) kanti izinga lokushisa elifanele lokusebenza liyi-68 kuya ku-79 °C (154 kuya ku-174 °F).
Izinga lokushisa eliphansi elifanele lokukhishwa kwekhofi lingu-91 °C.
