Izinhlobo Zesilinganiso Se-Thermometer
Ukuze i-thermometer isetshenziswe ukukala izinga lokushisa, idinga ukuchazwa esikalini. Izikali ezimbili ze-thermometer ezisetshenziswa kakhulu isikali se-Celsius kanye nesikali se-Fahrenheit. Isikali sokushisa esisetshenziswa kakhulu e-Indonesia isikali se-Celsius. Elinye igama lesikali se-Celsius isikali se-centigrade. I-Centigrade = izinyathelo eziyikhulu. Isikali se-Fahrenheit sivame ukusetshenziswa e-United States noma emazweni anobusika obubandayo. Isikali sokushisa esibaluleke kakhulu kwisayensi isikali esiphelele, noma isikali se-Kelvin. Isikali se-Kelvin sizoxoxwa kamuva.
Izikali zeCelsius neFahrenheit zisebenzisa amaphuzu okuqandisa nokubila kwamanzi njengamaphuzu aqinile. Iphuzu lokuqandisa lento yizinga lokushisa lapho izigaba eziqinile neziwuketshezi zisesilinganisweni sokushisa . Ngokuphambene nalokho, iphuzu lokubila lento yizinga lokushisa lapho izigaba zoketshezi negesi zisesilinganisweni sokushisa. Amaphuzu okuqandisa nokubila ahlala eshintsha ngokucindezela komoya, ngakho-ke ukucindezela komoya kumele kunqunywe kuqala. Ngokuvamile sisebenzisa ukucindezela okujwayelekile, okungu-1 atm (umkhathi owodwa). Umkhathi uyiyunithi yokucindezela komoya.
Isikali se-Celsius
Iphuzu eliqondile eliphezulu lesikali seCelsius lisebenzisa iphuzu lokubila lamanzi ahlanzekile, kanti iphuzu eliqondile eliphansi lesikali seCelsius lisebenzisa iphuzu lokuqandisa lamanzi ahlanzekile. Iphuzu lokuqandisa lamanzi ahlanzekile (elibizwa nangokuthi iphuzu leqhwa) lingu-zero degrees Celsius (0 ° C), kanti iphuzu lokubila lamanzi ahlanzekile (elibizwa nangokuthi iphuzu leqhwa) lingu-100 degrees Celsius (100 ° C). Phakathi kwephuzu leqhwa nephuzu leqhwa kungu-100 degrees. Kuma-thermometer asebenzisa isikali seCelsius, amazinga okushisa aphansi kunephuzu leqhwa avame ukuphawulwa ngezinombolo ezingezinhle.
Isikali se-Fahrenheit
I-Fahrenheit yayifuna ukuthi zonke izikali zokushisa zibe zinhle. Ngakho-ke, wakhetha u-0 ° F ngezinga lokushisa lengxube yeqhwa namanzi anosawoti (izinga lokushisa elibanda kakhulu elingafinyelelwa amanzi). Lapho elinganisa amazinga okushisa ephuzu leqhwa kanye nephuzu lomusi, izinombolo eziboniswe esikalini se-Fahrenheit zaziyizingxenyana. Ekugcineni washintsha isikali ukuze amazinga okushisa ephuzu leqhwa kanye nephuzu lomusi abe izinombolo eziphelele.
Ngokwesilinganiso se-Fahrenheit, iphuzu lokubanda lamanzi ahlanzekile (iphuzu leqhwa) lingu-32 degrees Fahrenheit (32 o F) kanti iphuzu lokubila lamanzi ahlanzekile (iphuzu lomusi) lingu-212 degrees Fahrenheit (212 o F). Phakathi kwephuzu leqhwa nephuzu lomusi kungama-degrees angu-180. Amanzi ahlanzekile ngamanzi angaxubene nezinye izinto. I-H20 Ehlanzekile.
Uma sithi izinga lokushisa elithile, khona-ke silibiza ngokuthi amadigri Celsius (oC) noma amadigri e-Fahrenheit (oF). Isibonelo: izinga lokushisa lamanzi ashisayo = 100 oC noma 180 oF. Izinga lokushisa lomzimba wami = 98 oF. Ngakolunye uhlangothi, uma sithi ushintsho lokushisa noma umehluko ekushiseni, khona-ke sikubiza ngokuthi Amadigri e-Celsius (Co) awu Amadigri e-Fahrenheit (FoIsibonelo: izinga lokushisa lamanzi lokuqala lingu-20 oC. Ngemva kokushiswa, izinga lokushisa lishintsha libe ngu-50 oC. Ngakho-ke, amanzi abhekana nokushintsha kwezinga lokushisa okungu-30 Amadigri e-Celsius (30 C)o).
