Chinyorwa nezve Kushandurwa kwezviyero zvekupisa
Chikero cheCelsius nechikero cheFahrenheit zviyero zvakasiyana zvekupisa. Kana tembiricha yechinhu ikayerwa uye ikatsanangurwa pachikero cheCelsius, saka tinoda kutaura tembiricha yechinhu pachikero cheFahrenheit tobva tachichinja kubva pachikero cheCelsius kuenda pachikero cheFahrenheit. Muchikamu chino, tinodzidza kushandura kana kushandura chikero chekupisa.
Pakumanikidzwa kwe1 atm, tembiricha yechando yethermometer yeCelsius = 0 oC, nepo Fahrenheit thermometer = 32 oF. Kusiyana neizvi, pakumanikidzwa kwe1 atm, tembiricha ye nzvimbo yekubikira thermometer yechikero cheCelsius = 100 oC, nepo thermometer ine chikero cheFahrenheit = 212 oF.
Kuti zvive nyore kwauri kushandura chikero cheCelsius kuenda kuchikero cheFahrenheit kana kushandura chikero cheFahrenheit kuenda kuchikero cheCelsius, yeuka 0 oC = zana oF na 100 oC = zana oF. Pachikero cheCelsius, pakati pe0 oC uye 100 oC i100oPaunenge uri pachikero cheFahrenheit, uri pakati pe32 oF kusvika 212 oF kune 180o.
3.1 Chinja chikero cheCelsius kuita chikero cheFahrenheit
Kuti uwane tembiricha pachikero cheFahrenheit (T), wedzera tembiricha pachikero cheCelsius (T C ) kutanga ne9/5 wobva wawedzera 32 o.
3.2 Chinja chikero cheFahrenheit kuita chikero cheCelsius
Kuti uwane tembiricha pachikero cheCelsius (T C ), deredza tembiricha pachikero cheFahrenheit (T F ) ne32 o , wobva wawedzera ne5/9.
4. Thermometer yegesi inotenderera nguva dzose
Kare, takadzidza maitiro ekugadzirisa thermometer. Thermometer yatinoshandisa i mercury thermometer isina chikero. Kana tikagadzirisa ma thermometer maviri emhando dzakasiyana, akadai se mercury thermometer ne alcohol thermometer, ma thermometer maviri aya akafanana chete pa 0 o C (kana 32 o F) uye 100 o C (kana 212 o F). Kana tikashandisa ma thermometer maviri kuyera tembiricha yemhepo, nhamba dzinoratidzwa ne thermometer yega yega hadzisi dzakafanana. Mercury thermometers dzinogona kuratidza 48 o C, nepo alcohol thermometers dzichiratidza 46 o C. Izvi zvinodaro nekuti kumhanya kwekuwedzera kwe mercury ne alcohol kwakasiyana. Saizvozvowo kune mamwe marudzi ema thermometers, akadai se bimetallic thermometers, nezvimwewo. Chikero chetembiricha chinosarudzwa nenzira iyi chinoenderana zvikuru nemhando yezvinhu zvinoshandiswa.
Nekuti chikero chekupisa chinotsanangurwa uchishandisa thermometer chinowanzova nekushomeka, tinoda thermometer yakajairwa. Kuvapo kwe thermometer yakajairwa kunotibatsira kugadza chikero chekupisa zvakanyatsonaka, tisingatarisiri kuti chinhu chacho ndechei.
Thermometer inenge yakakwana ithermometer yegesi isingachinji. Nheyo inoshanda yethermometer yegesi isingachinji ndeyekuti, vhoriyamu yegesi inochengetwa kuitira kuti igare yakamira kana kuti isingachinji. Zvino, kana tembiricha ikawedzera, pressure yegesi inowedzerawo. Mupipe 1 nemupipe yechipiri mune mercury. vhoriyamu yegesi inochengetwa kuitira kuti igare yakamira, nekusimudza kana kudzikisa pipe mbiri kuitira kuti pamusoro pemercury mupipe 1 parambe pachiratidzo chereferensi. Kana tembiricha ikawedzera, pressure yegesi mupipe inowedzerawo. Naizvozvo, pipe mbiri inofanira kusimudzwa kuti vhoriyamu yegesi igare yakamira. pressure yegesi inogona kuzivikanwa nekuverenga kukwirira kwekhoramu yemercury (h) mupipe 2. Kana uchishandisa nzira yemaoko, ingoyeuka kuti koramu yemercury i760 mm = 1 atm (1 atm). Muthermometer yegesi isingachinji yakaoma, kune pressure counter. Matangi akazadzwa negesi akagadzirwawo kuitira kuti gasi rigare riri muvhoriyamu yakatarwa. Saka, iyo yakayerwa inongochinja chete mupressure.
5. Kelvin Scale
Kana chidimbu chiri pachati chiri pamusoro chakadhirowa kuti chicheke axis yeTo C , saka kana kumanikidzwa kwegasi kuri 0, tembiricha yegasi = -273.15 o C. Pamwe tinofunga kuti tembiricha yegasi pa pressure ye0 inosiyana zvichienderana nerudzi rwegasi riri muchubhu ye thermometer yegasi isingachinji. Zvichibva pakuyedza, kunyangwe rudzi rwegasi rwakasiyana kana kumanikidzwa kwegasi kwava zero, tembiricha inogara ichikosheswa pa -273.15 o C. Saka, tinogona kushandisa tembiricha iyi sechiyero chetembiricha chakajairwa (chinozivikanwawo sekupisa kwe zero zvachose). Tembiricha iyi ye zero chaiyo inozivikanwa sechiyero chakazara kana Kelvin scale. Kelvin izita raLord Kelvin (1824-1907), aimbova nyanzvi yefizikisi yeBritain.
Pachikero ichi, tembiricha inoonekwa muKelvin (K), kwete muKelvin ( o K) degree. Nguva iri pakati pemadhigiri yakafanana neiri pachikero cheCelsius, asi zero inochinjirwa ku0 K. Saka 0 K = -273.15 o C uye 273.15 K = 0 o C. Tembiricha iri muchikero cheCelsius inogona kuchinjwa kuita chikero cheKelvin nekuwedzera 273.15. Saizvozvowo, tembiricha yechikero cheKelvin inogona kuchinjwa kuita chikero cheCelsius nekuderedza 273.15.
T (K) = T ( o C) + 273.15
T ( o C) = T (K) – 273.15
