"Ngoba ngaphandle kwamanzi futhi hhayi lapho, futhi hhayi syudy ..." kwaqalwa ifilimu elidala elihle. Ngempela, ngaphandle kwamanzi, ukuphila emhlabeni kumane kungenzeki. Amanzi adingekayo kuzo zonke izinto eziphilayo: izitshalo, izilwane, kanye nendoda. Amanzi ahlanganisa ngaphezu kuka-60% ebusweni bomhlaba wethu, amanzi angu-65% omzimba womuntu. Amanzi - into ekhethekile, ekwazi ukuthatha uhlobo lomkhumbi lapho itholakala khona. Kungaba ngamatsatfu amathathu: okuqinile, okumanzi nokwehla. Okuhlangenwe nakho okuthakazelisayo kuyoba yindlela enhle kakhulu yokuba izingane zesikole zijwayele amanzi, nezindawo zalo namakhono azo. Ukuqhuba ukuhlolwa ngamanzi, awudingi imishini enzima noma izinyathelo zokuphepha ezengeziwe, okwanele kokusungula okuyisisekelo okutholakala kuwo wonke umuntu.
Ukuhlolwa okuthakazelisayo ngamanzi ezinganeni
Ngakho-ke, ake siqale ukuzama.
Ukuhlangabezana namanzi nosawoti
Ngolwazi, sidinga:
- amanzi;
- ingilazi;
- ufulawa usawoti.
Isifundo sokuhlangenwe nakho
- Gcwalisa ingilazi ngamanzi kuze kube semlonyeni.
- Ngokushukumisa ngobumnene okuqukethwe kweglasi ngetambo elincane noma i-toothpick, siqala ukuthululela usawoti kulo.
- Esikhathini sokuhlolwa, kuvela ukuthi egumbini lamanzi ungangezela cishe isigamu ingilazi kasawoti ngaphandle kokuchitha amanzi.
Incazelo
Lapho amanzi esesimweni segazi, kukhona isikhala samahhala phakathi kwama-molecule ayo, agcwele ama-molecule akasawoti. Lapho zonke izindawo zamahhala zigcwele ama-molecule akasawoti, zizophela ukuchithwa emanzini (isixazululo sizofinyelela saturation) futhi uketshezi luzothululela phezu kwengqikithi yesilazi.
Thola amanzi namaphepha
Ngolwazi, sidinga:
- isisindo;
- amapensela noma izimpawu;
- ukunamathisela;
- iphepha elimbala elinabantu abaningi;
- ububanzi obubanzi - ibhasi noma i-tray;
- amanzi.
Isifundo sokuhlangenwe nakho
- Sika iphepha emagcekeni ngecala lika-15 cm. Gcwalisa lezi zigca bese uhlukanisa izimbali ezivela kubo. Siphonsa amacembe ezimbali.
- Beka izimbali esitsheni samanzi.
- Ngemva kwesikhashana, izimbali ziqala ukuvula izikhala zazo. Isikhathi esithatha sincike ekubambeni kwephepha.
Incazelo
Izimbali zephepha ezikhazimulayo ziqala ngokuthi amafayili ephepha ayathululelwa ngamanzi, leli phepha liba nzima kakhulu futhi libuyele phansi ngaphansi kwesisindo salo.
Uhlangabezana nebhola namanzi
Ngolwazi, sidinga:
- ibhaluni lomoya;
- ingilazi yesilazi;
- amanzi;
- i-kettle.
Isifundo sokuhlangenwe nakho
- Gcwalisa ibhaluni ngamanzi abandayo ukuze angadluli entanyeni yembiza engilazi engamalitha amathathu.
- Sishisa amanzi emthonjeni bese siwugcwalisa ngembiza.
- Sishiya amanzi embizeni isikhashana kuze kube yilapho izindonga zembiza zifudumala.
- Thela amanzi embizeni bese ubeka ibhola entanyeni.
- Sibheka ibhola liqala "ukuncela" embizeni.
Incazelo
Emva kokuba izindonga zembiza zivutha futhi amanzi athululiwe kuwo, baqala ukunikeza ukushisa emkhathini ngaphakathi embizeni. Umoya, ngokulandelana, uqala ukushisa futhi ama-molecule ayo ahamba ngokushesha. Uma sigubha entanyeni yembiza ngebhola, sidala umehluko wezingcindezi ngaphakathi nangaphandle kwayo. Ngenxa yalokhu, ibhola lidonsa embizeni.
Ukuhlangabezana namanzi kanye nezinyopho zokugcoba
Ngolwazi, sidinga:
- isitsha esinamanzi;
- isepha;
- ushukela ocolile;
- ama-toothpicks enkuni.
Isifundo sokuhlangenwe nakho
- Sifaka ama-toothpicks ambalwa emathini amanzi.
- Maphakathi nesitsha, faka ngokucophelela ushukela ohlanjulisiwe ushukela futhi ngemva kwemizuzwana embalwa sibona ukuthi ama-toothpicks aqala kanjani ukuhambisa
eceleni kweshukela. - Beka insipho maphakathi nesitsha bese ubukela ukuthi ama-toothpicks aqala kanjani ukuhamba ngendlela ehlukile.
Incazelo
Ushukela ocolile ubamba amanzi futhi ngaleyo ndlela kudala ukugeleza okuqondiswe phakathi kwesitsha. Insipho inciphisa kakhulu ukungezwani kwamanzi phakathi nendawo, futhi izinyopho zidonsa yizindawo ezinomthamo ongaphezulu ophezulu.
Futhi, izingane zizoba nesithakazelo ekuhlolweni kokukhipha amakristalu .
