Sitshele kangaki ukuthi ulwazi lwesikole luzofika ngokushesha noma kamuva? Yiqiniso akuzona zonke, kodwa ngezinye izikhathi kuvela iqiniso eliyiqiniso. Uma udinga ukufaka amashalofu esikhwameni noma ukudweba umugqa oqondile odongeni , kuyoba nzima ukwenza lokhu ngaphandle kwezinga. Izinga lokwakhiwa kwamanzi lingatholakala kalula kunoma yisiphi isitolo sokwakhiwa, futhi ukwenza kube njalo kunzima kakhulu. Kwanele ukukhumbula imithetho ye-physics ezenzeni ezihlangene.
Isimiso sokusebenza kwamanzi amanzi
Udinga nje ukuthola i-hose engavamile egcwele futhi ugcwalise nge-liquid. Okulandelayo, sizobheka ngokuningiliziwe indlela yokwakha nokusebenzisa izinga lamanzi:
- Ihubhu eliguquguqukayo elinamanzi eligcwele amanzi kusukela kumathinathi bekuyoba okungalungile. Lokhu kuzosusa ingcindezi yamabhulebhu emoyeni, okuzoholela ekulinganiseni okungalungile. Udinga ukulungisa ibhakede lamanzi aqoshiwe. Kuphakama umbuzo ozwakalayo, kungcono ukudweba amanzi ezingeni lamanzi. Eqinisweni, kungaba nhlobo noma yiluphi udaba olubalabala kusukela odwebeni lwezingane ukuya ku-potassium permanganate. Futhi, impendulo yombuzo, kungcono ukupenda amanzi emanzini wamanzi, umbala wokudla ungase ube.
- Okulandelayo, sigubha umkhawulo owodwa wephasi ebhakedeni, owesibili siwukwehlisa phansi bese ususa amanzi ukuze ugcwalise ngokuphelele ithini. Siyidlulisela kuze kube yilapho kungekho bubble olulodwa e-tube. Bese uqhaqha ukuphela kwebhulethi ngomunwe wakho. Isiphetho sesibili siphinde sigwetshwe ngomunwe futhi sithathwe ebhakedeni. Siphakamisela lezi ziphetho ezimbili futhi sihlole idivayisi yethu: uma amanzi esesilinganisweni esifanayo, konke kwenziwa ngendlela efanele.
- Ukunemba kwezinga lamanzi kuxhomeke ngokuphelele ekuqineni komkhiqizo. Uma kungekho moya wangaphakathi, i-tube ayiphambuki - konke kuzolinganiswa ngendlela efanele.
Isicelo sokwakhiwa kwamanzi
Ukwenza amamaki amabili ngokuphakama okufanayo emaphethelweni ahlukene odonga, udinga ukusebenza ngamabili. Okokuqala usebenzisa isicelo esisodwa bese udweba uphawu. Sibamba ukuphela kwebhulethi endaweni futhi sidlulise ngokucophelela ingxenye yesibili. Qinisekisa ukuvala ukuphela kwe-tube ngeminwe yakho ukuze ugcine isimiso sesistimu. Ezingeni zokuthenga eziphelile kukhona ama-flasks akhethekile emaphethelweni, lapho amamaki nezilinganiso sezivele ziphawulwe. Lokhu kwenza lula umsebenzi ngezikhathi ezithile. Kwanele ukuphakamisa noma ukunciphisa kuze kube yilapho amanzi emaphethelweni womabili asezingeni elifanayo. Ukuze uthole amanzi okuzenzela, mane umaka uphawu ngokumaka. Uma ugcwalisa amanzi ngesilinganiso esilungile, kubalulekile ukuthi liwuketshezi ekamelweni lokushisa. Ungalokothi uhlwithe izikhumba zamaflasks, ngoba lokhu kuphula ngokuphelele isimiso sokusebenza kwezitsha zokuxhumana.
Ngemuva kokuthi wenze amanothi amabili, adinga ukuhlanganiswa emgqeni owodwa. Kule njongo kulula ukusebenzisa intambo enemibala. Ulungisa ukuphela kwamamaki amabili, kancane udonsa intambo, futhi ushaya udonga, ushiya umzila. Indlela efanayo isetshenziselwa ngentambo. Kungumqondo omuhle ukuphindaphinda kabili-hlola umsebenzi ngezinga le-bubble, uma usebenzisa
Uma udinga ukudlulisa umugqa ohlangothini oluphambene noma kwelinye ikamelo, isimiso sokusebenza sihlala sinye. Nakhu kuyadingeka ukuthatha i-hose ngokuyiqiniso, futhi esifundeni ngasinye esilandelayo siphinde sithathe uphawu lokuqala. Lokhu kuzokwenza kube lula ukugwema ukungalungi nokungaqondile ekusetshenzisweni kwemigqa yokulawula. Uma kufanele usebenze wodwa, ukuphela komkhawulo we-hose kulungisiwe, futhi okwesibili kuthathwa ibanga elifunayo. Kwanele ukubeka amamaki okulawula kuqala odongeni ngalunye, kusukela kokuvamile, bese uqhubekela kwabanye. Njalo qinisekisa ukuthi i-hose ayiguquki, ayikho ikinks, futhi ihlezi phansi phansi.
