Ukususela ebuntwaneni siye safundiswa ukuba i-thermometer ephukile yintlekele kwinqanaba lehostela. Kamva le ngcamango ibonakala ingaphantsi kwentloko yethu, kwaye xa i-thermometer iphazamisekile ekhaya, akukho mntu uyazi ukuba yenzeni. Ngoko, makhe sihlaziye isicwangciso senzo kule meko.
I-mercury thermometer yaphuka: iziphumo
Umphunga weMercury uyingozi kakhulu. Ekuqaleni, kunzima ukuqaphela ukutyhefuza, kuba iimpawu zalo ziyazi kakuhle zonke iindawo ezihamba phambili. Ukusukela entloko, ukukhathala, ukucabangela okanye ukucaphuka. Yonke le mpawu, ngokukhawuleza asiqapheli kwisigqi sokuphila. Kodwa imiphumo emva kokuba i-thermometer idibeneyo inokudakalisa kakhulu: izibini zichaphazela kakubi inkqubo yentsholongwane yomntu kunye neentso. Ngoko kuyimfuneko ukuba senze ngokukhawuleza kwaye ngokuzithandela.
Emva kokuba unike izibonelelo ze-thermometer kubaphathi abanegunya, kufuneka nilungiselele igumbi. Lungisa isisombululo se-0.2% se-potassium permanganate okanye isisombululo sesobho. Ukulungiselela kwayo, xuba i-30 g ye-soda kunye ne-40 g yesepha, yonke iyanciphisa ilitha yamanzi. Zonke iindawo ezazisondele kwindawo ye-mercury kufuneka ziphathwe ngokucophelela ngesisombululo esilungisiweyo. Emva kweentsuku ezimbalwa, isisombululo siyahlanjulwa kwiindawo.
Ungasusa njani i-thermometer ephukile?
Qinisekisa ukuba uvule iwindi kwigumbi apho waqhekeza i-thermometer. Ungavumeli ulungiso! Vala iminyango ngokuqinileyo ukuze umoya ungangeni kwihostela. Gcina ukhumbule ukuba i-mercury isasazeka ngokulula kwiintsimi, idibanisa kwiindawo.
Ngaphambi kokuqokelela i-mercury, kuyimfuneko ukugqoka:
- iiglavu zerabha. Gwema ukunxibelelana nesikhumba;
- ipakethe ye-polyethylene ezinyaweni. Xa uqokelela yonke into, amaconsi e-mercury angakwazi ukunamathela ezinyaweni zakho, yingakho ususa kuphela iibhegi uze uzihlanganise ngokufanayo;
- ibhanti ye-cotton-gauze ebusweni. Ukuze ungagcini nge-mercury vapor, ngaphambi kokucwina i-mask ngesisombululo se-soda okanye amanzi ahlanzekileyo.
Ukuqokelela i-mercury ngokucophelela. Beka zonke iziqwenga ezivela kwi-thermometer ukuya kwijelo yeglasi ngamanzi abandayo. Amanzi aya kuthintela ukufudumala kwe-mercury kwi-can.
Kuthekani ukuba i-thermometer iyaqhekeka kwaye kukho ezininzi ezincinci zamanzi ezisezantsi? Basenokuqokelelwa basebenzisa ezi zixhobo:
- isirinji;
- peyubha;
- uphahla;
- iphephandaba elimanzi okanye ucezu loboya bekotoni;
- tape okanye udongwe;
- Iibhontshi zokudweba okanye ukucheba.
Qinisekisa ukuba ukhangele kuyo yonke imifuziselo kunye namacangca. Sebenzisa isirinji ngenaliti enqamle okanye ipayari kule njongo.
Ukuba ukrokrela ukufumana i-mercury phantsi kwebhodi okanye ipakethi, kufuneka isuswe kwaye ihlolwe. Kwimeko apho kufuneka uqoke i-mercury ixesha elide, thabatha ikhefu yonke imizuzu eyi-15 uze uphefumle umoya omtsha.
Indawo apho i-thermometer yaqhekeka imele ikhanyiswe ngotshani. Ngomgama omfutshane unokubeka isibane setafile. Ukukhanya kufuneka kuwele kwindawo ye-mercury ecaleni. Ngoko onke amaconsi e-silvery aya kubonakala kwaye awuyi kuphanga.
Ungaze ulahle i-metal eqokelelweyo kwi-refuse chute okanye kwinkqubo yokuthuthwa kwamanzi. Akunandaba nokuba i-mercury ivela emva koko,
Kukuphi ukubiza ukuba i-thermometer yaphula?
Ngaphambi kokuba uqale ukuqokelela i-mercury ecaleni kwigumbi, qiniseka ukuba ubike isiganeko kwiinkonzo ezifanelekileyo. Ndingazibiza phi ukuba i-thermometer yaphula? Kukho amaziko akhethekileyo ajongene nokupheliswa kweziphumo zeli ganeko. Inkonzo yokuqala, apho kufuneka uhambe khona, ukuba i-thermometer iyaphulwa yiNgqongqoshe yeemeko ezixakekayo. Ngokwefowuni eyaziwayo ukususela ebuntwaneni, kuyimfuneko ukubiza nokufumana iingcebiso kwizenzo kwindawo.
