Dab tsi yog qhov ntsuas kub? Kev piav qhia: Unit of kub yog Joule. Nws yog ib daim ntawv ntawm lub zog uas yuav kis tau los ntawm ib qho khoom ntawm qhov kub thiab txias mus rau qhov qis dua.
Ntawm no, dab tsi yog qhov dimension ntawm qhov kub thiab txias?
Qhov kub thiab txias , kuj hu ua thermodynamic kub , yog kub ntawm ib qho khoom ntawm qhov ntsuas qhov twg 0 raug coj los ua kiag li xoom. Qhov kub thiab txias Qhov ntsuas yog Kelvin (degree units Celsius) thiab Rankine (degree units Fahrenheit).
Dab tsi yog qhov qauv ntawm qhov ntsuas kub gradient?
Cov " kub gradient "yog ib" qhov seem quantity" qhia nyob rau hauv units ntawm "degree per unit length". Kub gradient yog sau li dQ/dt. Nws yog siv nyob rau hauv meteorological department thiab nyob rau hauv kev kawm txog cov teebmeem ntawm huab cua.

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
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 ua rau lub caij nyoog hloov pauv ntawm qhov kub thiab txias?
Cov no yog tshwm sim feem ntau los ntawm kev txo cov hnub ci cua sov los ntawm huab thiab nce nyob rau hauv nto latent tshav kub tso tawm los ntawm nto ntub dej nce vim los nag. Lawv hais tias cov kev hloov mus sij hawm ntev ntawm nag lossis daus thiab huab yuav yog qhov ua rau txo qhov kub thiab txias thiab qhov tsis zoo DTR tiam sis
Dab tsi yog cov units siv rau qhov kub thiab txias?
Qhov ntsuas feem ntau yog cov ntsuas Celsius (yav tas los hu ua centigrade), qhia ° C, Fahrenheit scale (denoted ° F), thiab Kelvin scale (denoted K), tom kawg uas yog feem ntau siv rau kev tshawb fawb los ntawm cov rooj sib tham ntawm International System of Units (SI)
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
