Kelvin yog a kub scale tsim kom xoom degrees K txhais tau tias yog xoom (ntawm qhov xoom, ib qho kev xav kub , txhua qhov kev txav ntawm lub cev tsis muaj zog - txhua qhov tseeb kub yog siab tshaj xoom) thiab qhov loj ntawm ib chav tsev yog tib yam li qhov loj ntawm ib degree Celsius.

Ib yam li ntawd, puas yog Kelvin kub lossis txias?

ntsuas kub uas tam sim no lub npe hu ua Kelvin Ntsuas ntsuas kub. Qhov ntsuas no tau siv los ntawm cov kws tshawb fawb los ntsuas qhov tsis txaus ntseeg kub thiab txias kub. Nyob rau Kelvin nplai, degrees raug hu cov leeg (K) thiab tsis siv lub cim cim (°). Yog li 100 degrees Kelvin sau li 100 K.

Tsis tas li ntawd, qhov ntsuas kub ntawm Kelvin yog dab tsi? Kelvin yog ib qho tseem ceeb nplai siv nyob rau hauv feem ntau ntawm science. Qhov sib txawv loj yog tias nws yog nyob ntawm ib qho point (zero kiag li) uas tau muab tus nqi ntawm 0 degrees. Los ntawm qhov ntawd, cov nplai nce los ntawm cov degrees uas yog qhov loj tib yam li Celsius degrees.

Tsis tas li, leej twg siv Kelvin rau qhov kub thiab txias?

Dej khov ntawm 32 degrees Fahrenheit thiab rhaub ntawm 212 degrees Fahrenheit. Cov Kelvin scale yog siv los ntawm physicists thiab lwm yam kws tshawb fawb uas yuav tsum tau sau meej heev kub . Cov kelvin scale yog tib chav ntsuas ntsuas kom suav nrog kub rau "zero kiag li," tag nrho tsis muaj lub zog cua sov.

Cov xim twg yog 3000 Kelvin?

Xim kub yog conventionally qhia nyob rau hauv cov leeg , siv lub cim K, ib chav ntsuas rau qhov kub thiab txias. Xim kub tshaj 5000 K yog hu ua "txias xim " (xiav), thaum qis xim kub (2700 – 3000 K) raug hu ua "sov xim "(daj).
