Hom Ntsuas Kub
Yuav kom siv tau lub ntsuas kub los ntsuas qhov kub, yuav tsum tau teeb tsa ib lub nplai. Muaj ob lub nplai. lub ntsuas kub Cov nplai siv feem ntau suav nrog Celsius thiab Fahrenheit nplai. Qhov ntsuas kub feem ntau siv hauv Indonesia yog Celsius nplai. Lwm lub npe rau Celsius nplai yog centigrade nplai. Centigrade = ib puas kauj ruam. Fahrenheit nplai feem ntau siv hauv Tebchaws Meskas lossis cov tebchaws uas muaj lub caij ntuj no. Ib qho nplai kub tseem ceeb hauv kev tshawb fawb yog qhov nplai tsis muaj qhov kawg, lossis Kelvin nplai. Kelvin nplai yuav raug tham tom qab.
Cov ntsiab lus ruaj khov ntawm Celsius thiab Fahrenheit nplai siv cov ntsiab lus khov thiab cov ntsiab lus npau ntawm dej. Lub ntsiab lus khov ntawm ib yam khoom yog qhov kub uas cov khoom khov thiab cov kua nyob rau tib qhov kub. kev sib npaug ntawm thermal. Ntawm qhov tod tes, qhov kub ntawm ib yam khoom yog qhov kub uas cov kua thiab cov pa roj nyob hauv qhov sib npaug ntawm thermal. Cov khov thiab cov kub ib txwm hloov pauv nrog lub zog cua, yog li lub zog cua yuav tsum tau txiav txim siab ua ntej. Peb feem ntau siv lub zog txheem, uas yog 1 atm (ib puag ncig). Ib puag ncig yog ib chav ntawm lub zog cua.
Celsius nplai
Qhov chaw ruaj khov sab saud ntawm qhov ntsuas Celsius siv qhov kub npau ntawm dej ntshiab, thaum qhov chaw ruaj khov qis dua ntawm qhov ntsuas Celsius siv qhov chaw khov ntawm dej ntshiab. Qhov chaw khov ntawm dej ntshiab (tseem hu ua qhov dej khov) yog xoom degrees Celsius (0)o C) thiab lub ntsiab lus kub ntawm dej ntshiab (tseem hu ua lub ntsiab lus ntawm cov pa dej) yog ib puas degrees Celsius (100o C). Nruab nrab ntawm qhov khov thiab qhov chaw ua pa yog 100 degrees. Ntawm cov ntsuas kub uas siv Celsius nplai, qhov kub qis dua qhov khov feem ntau yog cim nrog cov lej tsis zoo.
Fahrenheit nplai
Fahrenheit xav kom txhua qhov ntsuas kub zoo. Yog li ntawd, nws xaiv 0. oF rau qhov kub ntawm cov dej khov thiab dej ntsev sib xyaw (qhov kub txias tshaj plaws uas dej tuaj yeem ncav cuag tau). Thaum ntsuas qhov kub ntawm cov dej khov thiab cov pa dej, cov lej uas pom ntawm Fahrenheit nplai yog feem pua. Thaum kawg, nws hloov kho qhov nplai kom qhov kub ntawm cov dej khov thiab cov pa dej yog cov lej tag nrho.
Nyob rau ntawm Fahrenheit nplai, qhov khov ntawm dej ntshiab (ice point) yog 32 degrees Fahrenheit (32o F) thiab qhov kub npau ntawm dej ntshiab (qhov kub ntawm cov pa dej) yog 212 degrees Fahrenheit (212o F). Nruab nrab ntawm qhov dej khov thiab qhov chaw ua pa muaj 180 degrees. Dej ntshiab yog dej uas tsis sib xyaw nrog lwm yam khoom. H ntshiab20.
Thaum peb hais ib qho kub, ces peb hu nws degrees Celsius (oC) los yog degrees Fahrenheit (oF). Piv txwv li: qhov kub ntawm dej kub = 100 oC los yog 180 oF. Kuv lub cev kub = 98 oF. Ntawm qhov tod tes, yog tias peb hais tias qhov hloov pauv ntawm qhov kub thiab txias lossis qhov sib txawv ntawm qhov kub thiab txias, ces peb hu nws degrees Celsius (Co) atau degrees Fahrenheit (Fo). Piv txwv li: qhov kub ntawm dej pib yog 20 oC. Tom qab raug cua sov, qhov kub hloov mus rau 50 oC. Yog li ntawd, cov dej muaj kev hloov pauv kub ntawm 30 degrees Celsius (30 Co).
