Tshwj xeeb Thaum tshav kub kub muaj peev xwm yog tus nqi ntawm lub zog cua sov yuav tsum tau nce qhov kub ntawm ib yam khoom rau ib chav tsev ntawm qhov loj. Qhov tshwj xeeb Thaum tshav kub kub muaj peev xwm ntawm ib yam khoom yog lub cev khoom. Nws kuj yog ib qho piv txwv ntawm cov cuab yeej uas nws kim heev vim nws tus nqi yog proportional rau qhov loj ntawm qhov system raug tshuaj xyuas.

Yog li ntawd, tshwj xeeb cua sov yog ib qho cuab yeej dav?

Kub lub zog yog lub zog sab hauv ntawm ib yam khoom. Raws li kev ceeb toom, ib vaj tse dav ntawm ib yam khoom yog ib qho uas QUANTITY tseem ceeb. Tshwj xeeb kub muaj peev xwm yog ib intensive khoom . Tsis muaj teeb meem ntau npaum li cas aluminium koj muaj, nws muaj peev xwm nqus tau kub lub zog ntawm ib qho tshwj xeeb kub yog ib yam.

Tsis tas li ntawd, puas yog cov tshuaj kub tshwj xeeb lossis lub cev? Tshwj xeeb kub ntawm ib yam khoom yog tus nqi ntawm kub yuav tsum tau nce qhov kub ntawm ib gram ntawm cov khoom ntawd los ntawm ib tug degree celsius uas tsis nyob ntawm seb tus nqi ntawm cov khoom.

Ib tug kuj yuav nug, dab tsi txhais cov cua sov tshwj xeeb?

Tshwj xeeb kub yog tus nqi ntawm kub lub zog yuav tsum tau nce qhov kub ntawm lub cev ib chav tsev ntawm huab hwm coj. Tshwj xeeb kub tseem hu ua tshwj xeeb kub muaj peev xwm los yog loj tshwj xeeb kub . Hauv SI units, tshwj xeeb kub (cim: c) yog tus nqi ntawm kub Hauv joules yuav tsum tau nce 1 gram ntawm cov khoom 1 Kelvin.

Dab tsi yog tus qauv rau lub peev xwm kub?

Rau xam cov peev xwm kub , siv cov qauv : Thaum tshav kub kub muaj peev xwm = E / T, qhov twg E yog tus nqi ntawm kub lub zog muab thiab T yog qhov hloov pauv ntawm qhov kub thiab txias. Piv txwv li, yog tias nws siv 2,000 Joules ntawm lub zog rau kub nce ib qho thaiv 5 degrees Celsius, lub qauv yuav zoo li: Thaum tshav kub kub muaj peev xwm = 2,000 Joules / 5 C.

Nws txhais li cas yog tias ib yam khoom muaj lub peev xwm kub tshwj xeeb?

Cov cua kub tshwj xeeb yog Jg−oK. Yog li, tus nqi siab txhais tau hais tias nws yuav siv ntau lub zog los tsa (lossis qis dua) nws qhov kub thiab txias. Ntxiv cov cua sov rau qhov "tseem ceeb tshwj xeeb" qhov sib xyaw ua ke yuav ua rau nws qhov kub thiab txias sai dua li ntxiv cov cua sov rau cov cua kub tshwj xeeb

Qhov twg yog qhov chaw sov sov savanna?

Lub Savanna biome yog Tropical grassland. Nws nyob nruab nrab ntawm ob lub ntsiab lus, Tropic ntawm Cancer mus rau sab qaum teb thiab Tropic ntawm Capricorn mus rau sab qab teb. Cov cheeb tsam nruab nrab ntawm lub tropics yog dab tsi hu ua tropical grasslands. Lub biome npog ntau dua ib nrab ntawm Africa, feem ntau ntawm South America thiab ib feem ntawm Asia xws li Is Nrias teb

Yuav ua li cas hloov Kelvin los ntawm Celsius mus rau cov cua sov tshwj xeeb?

Lub peev xwm kub tshwj xeeb yog qhov kub xav tau los nce qhov kub ntawm 1g ntawm cov khoom los ntawm 1 degree Celsius. 1 degree Celsius = 1 degree Kelvin. Thaum daws qhov muaj peev xwm kub hauv Kelvin, Kelvin = Celsius vim qhov kev ncua deb ntawm ib qib mus rau qib tom ntej hauv Celsius thiab Kelvin yog tib yam

Puas muaj cov cua sov tshwj xeeb?

Tshwj xeeb kub. Qhov tseeb, cov nqi hluav taws xob tshwj xeeb ntawm cov khoom hloov pauv ntawm qib mus rau qib, tab sis peb yuav tsis quav ntsej qhov ntawd. Cov chav nyob feem ntau yog Joules ib gram-degree Celsius (J / g ° C). Qee zaum chav tsev J / kg K kuj siv
