I-thermometer ye-mercury ikhona phantse nganye kwikhabhinethi yezilwanyana njengethuluzi elichanekileyo lokulinganisa ubushushu bomzimba. Impendulo yodwa yeso sixhobo i-fragility yayo, kuba ngenxa ye-breakage evela kwiblabhu yeglasi igxobhoze insimbi yengozi eyingozi. Ngoko ke, i-mercury enetyhefu esuka kwi-thermometer idlalwa rhoqo - iimpawu zokuxiliswa akunakuze zifunyanwe ngokukhawuleza ngenxa yokuba isixa semveliso enetyhefu sincinci kakhulu ukuvela kwe-pathology enzima.
Iimpawu kunye neempawu ze-mercury zetyhefu nge-thermometer ephukile
Umthamo wesinyithi kwi-thermometer esezingeni elimalunga no-1 g. Le mali yesimo seemeysi phantsi kweemeko eziqhelekileyo ayinayo ingozi enkulu, ingakumbi ukuba iqokelelwe ngokukhawuleza kwaye iqokelelwe ngokupheleleyo, ilahlwe, ize ifike umoya.
Inyaniso kukuba i-metal echaziweyo ngokwayo ayizihlanganisi emzimbeni, nangona emva kokungcinywa ayinakunyuswa, kodwa isuswa ngokuqhelekileyo. I-Mercury enetyhefu esuka kwi-thermometer inokwenzeka kuphela ngokukhuphuka kwayo. Le nkqubo inxulumene nokubunjwa kweetrotti zetsimbi ngethuba le-oxidation.
Izibonakaliso neempawu zetyhefu yomshukela we-thermometer
Ukuxhatshazwa kweemichiza ezichaphazelekayo kubakho xa isithwathwa sensimbi esivela kwi-thermometer ephukile singasuswa kwigumbi. Ngokomzekelo, iibhola ze-mercury zihlala ziqhutywe kwiindawo eziphantsi komhlaba, phantsi kwe-plinth, zizinamathele kwiifenitshala zeefenitshala okanye kwimidlalo yezingane. Kwiimeko ezinjalo, isinyithi siqala ukuphuphuma ngokukhawuleza, kubangela ukutyhefuza. Ukuxilisa kubonakala ngoku:
- intloko;
- ukuhlaselwa kwangokubuthathaka;
- ukuphuma kwegazi kunye nobuzwe bezinsini;
- Ukunqongophala kwentsimbi ngeelwimi;
- ukukhwehlela okunqabileyo;
- ukuphefumula ukuphefumula ngexesha lokuzikhandla ngokomzimba;
- ukwanda kancinci kumbindi womzimba;
- ngamanye amaxesha - isicupunu;
- ukungonakaliswa kokugxininiswa kunye nenkumbulo;
- ukuthuthumela kwezandla ;
- ukucaphuka;
- kulala;
- Ukuphelelwa ngcamango kokubona ivumba kunye nokuthanda.
Njengoko kunokubonwa, iimpawu zetyhefu aziyiyo yonke into, iimpawu ezifanayo zihambelana nezifo ezahlukahlukeneyo zangaphakathi kunye neemeko zesifo. Ngako oko, ukuxiliswa nge-mercury vapor ayifumaneki, ngokukodwa kwinqanaba lokuqala. Ngenxa yoko, oogqirha bancome ukuba ukuba i-thermometer iphukile, ngokukhawuleza iqela iqela lexakeka, nangona zonke iibhola ezibonakalayo zetsimbi ziqokelelwa ngokucophelela kwaye zilahliwe ngokuzimela.
