Njalo ekuseni, “ukuchofoza” okujwayelekile kwegedlela likagesi elicimayo kuletha umuzwa wokuqiniseka.
Lokho okubonakala sengathi yindlela elula empeleni kuhilela ubunjiniyela obuhlakaniphile.
Ngakho-ke, iketile “lazi kanjani” ukuthi amanzi ayabila? Isayensi engemuva kwalo ihlakaniphile kunalokho ocabanga.
Umsebenzi wokuvala ngokuzenzakalela wekettle kagesi uncike esimisweni sokuzwa umusi.
Uma amanzi esezobila, umusi uhamba ngomsele omncane uye enzwa etholakala esivalweni noma esibambweni.
Ngaphakathi kwenzwa kukhonaidiski ye-bimetal, ezenziwe ngezinsimbi ezimbili ezinezinga lokunwebeka elihlukile.
Njengoba izinga lokushisa likhuphuka, idiski iyagoba futhi ibangele ukushintsha ukuze kunqunywe isekethe—kuyekiswa inqubo yokushisa.
Lonke lolu hlobo lokusabela lungokoqobo kuphela, aludingi zobuchwepheshe, kodwa luyashesha, lunembile, futhi luthembekile.
Ukuvala okuzenzakalelayo akukhona nje ukuze kube lula—kuyisici esiyinhloko sokuphepha.
Uma amanzi ebila omile futhi ukufudumala kuqhubeka, isisekelo sekettle singashisa kakhulu futhi sibangele umonakalo noma ngisho nomlilo.
Ukuvimbela lokhu, amaketela esimanje afakweizinzwa ezomile ngamathumbanomaama-fuse okushisa.
Uma izinga lokushisa lidlula umkhawulo ophephile, amandla anqanyulwa ngokushesha ukuze kuvikelwe ipuleti lokushisa kanye nezingxenye zangaphakathi.
Le mininingwane yomklamo ecashile iqinisekisa ukuthi ukubilisa amanzi kuhlala kuyindlela ephephile nengenazinkathazo.
Kusenesikhathiamaketela kagesikuncike kuphela ezindleleni zomshini ezisebenzisa amadiski omusi kanye ne-bimetal.
Namuhla, ubuchwepheshe buthuthuke babaizinhlelo zokulawula izinga lokushisa zikagesieziqapha ukushisa ngokunemba okuphezulu.
Amaketela esimanje angacima ngokuzenzakalelayo, agcine amazinga okushisa engaguquki, noma ahlele ukufudumala kusenesikhathi.
Amanye amamodeli avumela ngishoUhlelo lokusebenza kanye nokulawula izwi, okuvumela abasebenzisi ukuthi babilise amanzi bekude.
Lokhu kuthuthuka—kusukela ekucinyweni kwemishini kuya ekuphathweni kwezinga lokushisa okuhlakaniphile—kuphawula inkathi entsha yezinto zikagesi zasekhaya ezihlakaniphile.
Ngemuva kwalokho "kuchofoza" okulula kulele ubuhlakani besayensi yezinto zokwakha, i-thermodynamics, kanye nobunjiniyela bokuphepha.
Ukuzwela kwediski ye-bimetal, ukwakheka kwendlela yomusi, kanye nokusebenza kahle kokudlulisa ukushisa komzimba wekettle—konke kumele kuklanywe kahle.
Ngokuhlola okuqinile kanye nobuciko obuhle, igedlela elisezingeni eliphezulu lingamelana namazinga okushisa aphezulu kanye nokusetshenziswa njalo iminyaka.
Yile mininingwane engabonakali echaza ukuqina kwesikhathi eside kanye nokwethenjwa komsebenzisi.
Namuhla, i-kettle kagesi isiphenduke ingxenye ebalulekile yomswakama ohlakaniphile.
II-SunledUhlakaniphileIkettle kagesiihlanganisa ukulawulwa kokushisa okunembe kakhulu nokuvikelwa okubili kokuphepha, igcina ukuthembeka kokuvalwa kwesitimu yendabuko ngenkathi inezela ubuhlakani besimanje.
NgeUkulawula Izwi Nohlelo Lokusebenza, abasebenzisi bangasethaAmazinga okushisa asethwe kusengaphambili enziwe ngokwakho (104–212℉ / 40–100℃)noma ishejuliIzindlela zokugcina ukufudumala ezingu-0–6Hngqo kusuka kumafoni abo.
A isikrini esikhulu sedijithali kanye nesibonisi sokushisa sesikhathi sangempelayenza ukusebenza kube lula futhi kube nenhle.
Kusukela ekulawuleni okuhlakaniphile kuya ekuqinisekiseni ukuphepha, i-Sunled iguqula isenzo esilula sokubilisa amanzi sibe yinto ehlanjululwe kahle, elula.
Ngesikhathi esilandelayo lapho uzwa lokho “kuchofoza” okujwayelekile, zinike isikhashana sokwazisa isayensi engemuva kwakho.
Ukuvala okuzenzakalelayo akusikho nje ukulula—kungumkhiqizo weminyaka eminingi yokusungula izinto ezintsha.
Inkomishi ngayinye yamanzi ashisayo ayigcini nje ngokufudumala, kodwa futhi nobuhlakani obuthule bobunjiniyela besimanje.
