Qhov ntsuas feem ntau yog ntsuas ntsuas Celsius (yav tas los hu ua centigrade), ntsuas ° C, Fahrenheit scale (denoted ° F), thiab Kelvin scale (denoted K), tom kawg ntawm uas yog feem ntau siv rau kev tshawb fawb los ntawm cov rooj sib tham ntawm International System ntawm Chav tsev (SI).
Kuj nug, qhov ntsuas ntsuas twg yog siv rau qhov kub thiab txias?
Chav ntsuas kub: los ntawm fahrenheit mus rau celsius ua rau kelvin thiab rov qab. Degrees Fahrenheit, (tsim nyob rau hauv thaum ntxov 1700's los ntawm G. Daniel Fahrenheit), yog siv los sau cov qhov kub thiab txias ntsuas los ntawm meteorologists nyob rau hauv lub tebchaws United States.
Ib tug kuj yuav nug, dab tsi yog txawv units ntawm kub? Kub tuaj yeem ntsuas hauv Kelvin , Celsius, Fahrenheit, Rømer, Réaumur, Newton, Delisle thiab Rankine. SI unit rau kub yog Kelvin.
Ntawm no, 4 units ntawm qhov kub thiab txias yog dab tsi?
Plaub Loj yog Celsius , Kelvin , Fahrenheit , Rankine . Vim li cas peb thiaj xav tau 4 qhov sib txawv ntawm qhov ntsuas kub ( Celsius , Fahrenheit , Kelvin , thiab Rankine )? Yog vim li cas Centigrade feem ntau siv thoob ntiaj teb thaum muaj ib chav tsev ( Kelvin )?
Chav tsev kub thiab SI chav ntsuas kub yog dab tsi?
degree Celsius

Qhov cuam tshuam ntawm qhov kub thiab txias ntawm qhov sib faib coefficient yog dab tsi?
Ib qho inverse linear kev sib raug zoo tau pom ntawm qhov kub thiab txias thiab qhov sib faib coefficient. CEEB TOOM: Nyob rau hauv ib qho kev ntsuas kub, qhov sib faib coefficients isoflurane thiab sevoflurane txo qis thaum qhov kub nce. Sevoflurane qhia tau hais tias muaj kev solubility siab hauv Oxygent (TM) piv rau isoflurane
Cov tshuaj twg yog siv rau hauv cov khoom kub thiab txias?
Instant Kub thiab Cold Packs Raws li cov ntsev disassociates, tshav kub yog tso tawm nyob rau hauv ib qho exothermic cov tshuaj tiv thaiv los yog absorbed nyob rau hauv ib tug endothermic cov tshuaj tiv thaiv. Cov khoom lag luam tam sim no feem ntau siv ammonium nitrate lossis urea ua lawv cov ntsev tivthaiv; Cov pob kub feem ntau siv magnesium sulfate lossis calcium chloride
Qhov nqus thiab tso tawm ntawm lub zog cuam tshuam li cas rau qhov kub thiab txias thaum lub sij hawm muaj tshuaj tiv thaiv?
Nyob rau hauv endothermic cov tshuaj tiv thaiv cov enthalpy ntawm cov khoom yog ntau dua cov enthalpy ntawm cov reactants. Vim tias cov tshuaj tiv thaiv tso tawm lossis nqus lub zog, lawv cuam tshuam rau qhov kub ntawm lawv ib puag ncig. Exothermic cov tshuaj tiv thaiv cua sov ua rau lawv ib puag ncig thaum cov tshuaj tiv thaiv endothermic txias rau lawv
Dab tsi yog qhov dimension rau qhov kub thiab txias?
Quantity Dimension Alternatives Tam sim no, hluav taws xob A A Kub K K Tus nqi ntawm cov tshuaj mol mol Luminosity | Luminous siv cd cd
Dab tsi yog qhov kev sib raug zoo ntawm qhov kub thiab txias hauv HR daim duab?
Lub hnub qub ci, lossis luminosity, nyob ntawm lub hnub qub qhov kub thiab qhov loj. Yog hais tias ob lub hnub qub muaj qhov kub thiab txias, lub hnub qub loj dua yuav luminous. Daim duab Hertzsprung-Russell (H-R) hauv qab no yog ib daim duab tawg uas qhia txog qhov ntsuas kub thiab qhov luminosities ntawm ntau lub hnub qub
