Sonke sisebenzise i-thermometer ye-mercury ngamanye amaxesha ebomini bethu ukulinganisa ubushushu bomzimba. Sisixhobo esisetyenziswe ngokubanzi kwizinto ezininzi ngaphandle kokuba sisetyenziselwe ukuthatha ubushushu bomzimba. Ngenxa yokuba olu hlobo lwe-thermometer lubangela umngcipheko othile ngexesha lokusetyenziswa kwalo, kuye kwagqitywa kwelokuba kubuyiswe iithemometha ezintsha zedijithali. I-thermometer ye-mercury ingaba yingozi xa iphuka. Ke ngoko, siza kuchaza Kufuneka wenze ntoni xa ithemometha yeemeksi iphuka. Ngaba iyityhefu?
Kweli nqaku siza kukuxelela zonke iimpawu, ukusetyenziswa kunye nento onokuyenza ukuba ithemometha ye-mercury iyaqhekeka.
Ithemometha yeMercury
Ezi thermometer aziyonto ngaphandle kwesixhobo esakhiwe yintshatsheli kunye neinjineli zasePoland uDaniel Gabriel Fahrenheit. Yibhalbhu eyolula ngetyhubhu yeglasi ethe tyaba ngaphakathi eyintsimbi yemekyuri. Gcina ukhumbula ukuba Umthamo okuyo isinyithi ngaphakathi kwityhubhu ungaphantsi komthamo opheleleyo weetyhubhu. Ukuze wazi ukuba zithini amaxabiso obushushu, kukho amanani athile abonisa uluhlu lobushushu. Xa ubuzwa ukuba kutheni i-mercury isetyenziselwe olu hlobo lwe-thermometer, nangona iyingozi, iyaphendulwa ukuba kulula kakhulu ukutshintsha ivolumu yayo kuxhomekeke kubushushu.
Oko kukuthi, njengoko iqondo lobushushu liphezulu okanye liphantsi, liya kwanda ngakumbi okanye ngaphantsi. Ndiyabulela kulo msebenzi ukuze sikwazi ukumakisha ngaphambi nasemva kuyo yonke isayensi iyonke. Ukuphuhliswa kwethemometha ye-mercury kunokuququzelela ukuqhubela phambili kwesayensi malunga noku. Ke ngoko, luhlobo lwesixhobo ethathelwa ingqalelo unanamhla njengezona zixhobo zibalaseleyo.
Nangona kunjalo, nangona iye yaba yenye yezona zixhobo zibalaseleyo, azisasetyenziswa namhlanje. Nangona uluhlu lwamaqondo obushushu anokulugubungela lukhulu kakhulu, lunokwandiswa nangakumbi ngokuziswa kwe-nitrogen okanye nayiphi na igesi engena ngaphakathi. Kwaye ezi thermometers zinengozi ngokubanzi ekusebenziseni kwazo ezahlukeneyo.
Ukusetyenziswa kwe-thermometer ye-mercury
Iithemometha zeMercury zazisetyenziswa kwiindawo ezininzi ngaphandle kokuthatha ubushushu bomzimba. Kusekho amakhaya apho ezi themometha zibonwa kucango lokungena ukulinganisa ubushushu bendawo. Zazisetyenziswa nasezibhedlele ukulinganisa ubushushu bezigulana. Ezinye iindawo apho ithemometha yemercury yayisetyenziswa iibhanki zegazi, izifukamisi, ulingelo lweekhemikhali, iioveninjl. Umzi mveliso yayili candelo elalisebenzisa ithemometha yeemekyuri kwizityalo ezisebenzisa amandla, ukwazi ubume kunye nobushushu bemibhobho, ifriji kunye nezixhobo zokufudumeza, ukugcinwa kokutya, iinqanawa, iivenkile zokubhaka, iindawo zokugcina iimpahla, njl. Kufanelekile ukuba sikhankanye ukuba yonke into enxulumene nekhitshi ikwasebenzisa ezi thermometer.
Lazi ixabiso lobushushu kwakubalulekile ukuvelisa iimveliso okanye ukuqinisekisa iipateni ezithile. Siyazi ukuba imekyuri yinto yendalo enombumba wayo oyi-atomiki engama-80. Ibisoloko ifunwa iminyaka kwilizwe leemeteorology kuba beziyinxalenye yezixhobo zemozulu ezifana neebarometers, manometers nezinye izixhobo. Olunye uphononongo lubanga oko ukusetyenziswa kwesi sinyithi akukhuselekanga kubemi, ke ikhutshiwe kwintengiso kancinci kancinci.
Kufuneka wenze ntoni xa ithemometha ye-mercury iqhekeka
Imithetho iyalela ukuba akukho sixhobo siqukethe i-mercury esinokuthengiswa. Kwaye kukuba i-mercury ibonakalisiwe ukuba inomngcipheko omkhulu wezempilo kunye nokusingqongileyo. Phakathi kweziphumo zalo kukungcola kwamanzi, umhlaba kunye nezilwanyana.
Umngcipheko we-mercury ulele kumphunga. Ukuba ithemometha ye-mercury iyaqhekeka, iya kuvelisa umphunga onetyhefu onokurhoxa. Xa i-mercury ichithekile, kufuneka iqokelelwe ngokukhawuleza ngaphambi kokuba kubekho ezinye iziphumo ezimbi. Rhoqo, abantu abazi ukuba mabenze ntoni xa ithemometha yeemekyuri yaphuka. Kwezi ntlobo zeemeko, naphantsi kwazo naziphi na iimeko kufuneka kusetyenziswe isicoci okanye isicoci esicocekileyo. Akukwacetyiswa ukuba uthabathe iintsalela ze-mercury ngezandla okanye ugungxule ulwelo kwindlu yangasese okanye isinki
Njengoko besesitshilo ngaphambiliImekyuri inako ukungcolisa amawaka eelitha zamanzi. Ukuba sigalela intsalela ye-mercury ezantsi esinkini, siya kungcolisa amawaka eelitha ngokungeyomfuneko. Ukuba yinto engcolisayo kakhulu, inokubangela umonakalo omkhulu kwixabiso elincinci. Ngokunikezelwa kokungaguquguquki kwale nto, xa iwela emhlabeni, yahlulahlula ibe ngamathontsi amancinci kwaye inokwanda nakweliphi na icala. Ngokukhawuleza nje ukuba ithemometha iyehla kwaye kukhutshwa ulwelo, kungcono ukususa abantwana kunye nezilwanyana zasekhaya kuloo ndawo kwaye uvule iifestile okanye iingcango zokufaka umoya ekhaya.
Enye yeengcebiso ezilungileyo yile Sebenzisa ilaphu, iiglavu kunye neemaski ukuyicoca. Ngale ndlela, siya kukhuselwa nakweyiphi na imeko enokubakho yokuphefumla umphunga onetyhefu. Ukuba ithemometha iwela kwindawo ethe tyaba, kulula kakhulu ukuyicoca kunokuba umgangatho unentanda apho kungagalelwa khona amacandelo amancinci esinyithi. Kuyimfuneko ukuqinisekisa ukuba uphononongo olufanelekileyo kwaye ujonge onke amathontsi e-mercury emhlabeni, kuba angangcolisa kwaye abangele iingxaki ezinkulu. Ukuba siyalibala ukuqokelela amanye amathontsi kwaye nawuphina umntu okanye isilwanyana sichukumise okanye siphefumle igesi eyityhefu, kunokukhokelela kwityhefu, ukonakala kwengqondo, ukugaya ukutya kunye neengxaki zezintso.
I-Thermometers engaphantsi kwetyhefu kune-mercury
Ngenxa yobungozi bezi thermometer, kungcono ukuba ube nesikhokelo sokuthenga ithemometha ukukhetha ezo zinokutshintshwa ngokukhuselekileyo nangempumelelo. Kukho iintlobo ezininzi zeethemomitha ezingeyongozi kwaye zinentsebenzo ephezulu kakhulu.
Ndiyathemba ukuba ngolu lwazi ungafunda ukuba wenze ntoni xa kuphuka ithemometha yeemekyuri.
