Kelvin kub ntsuas , ib ntsuas kub muaj qhov tsis muaj pes tsawg hauv qab uas kub tsis muaj nyob. Tsis muaj pes tsawg, lossis 0 ° K, yog kub ntawm lub zog molecular yog yam tsawg kawg nkaus, thiab nws sib haum rau a kub ntawm -273.15 ° ntawm Celsius ntsuas kub.

Ib yam li ntawd, nws raug nug, Kelvin kub yog dab tsi?

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.

Ntxiv mus, Kelvin nplai ntawm kev ntsuas yog dab tsi? Cov Kelvin kub nplai yog qhov kub thiab txias nplai nrog xoom ntawm kiag li xoom. Vim tias nws yog qhov tseeb nplai , ntsuas ua siv lub Kelvin scale tsis muaj degrees. Cov kelvin (ceeb toom tsab ntawv me) yog lub hauv paus ntawm qhov ntsuas kub hauv International System of Units (SI).

Thiaj li, Kelvin ntsuas kub yog dab tsi Vim li cas peb thiaj siv nws?

Celsius thiab Fahrenheit nplai ob leeg tau tsim nyob ib ncig ntawm dej, qhov chaw khov, qhov kub thiab txias los yog qee qhov sib xyaw ntawm cov dej thiab tshuaj lom neeg. Cov Kelvin kub ntsuas yog siv los ntawm cov kws tshawb fawb vim tias lawv xav tau ntsuas kub qhov twg xoom qhia txog qhov tsis muaj tag nrho ntawm thermal zog.

Qhov nruab nrab lub cev kub hauv Kelvin yog dab tsi?

Kelvin kub nplai muaj qhov tsis muaj pes tsawg hauv qab uas kub tsis muaj nyob. Tsis yog xoom, yog tus kub sib raug rau a kub ntawm - 273.15 ° ntawm qhov ntsuas kub Celsius. Cov qhov kub thiab txias ntawm tib neeg lub cev yog 36.85 0c. Kub hauv kelvin = 36.85 + 273.15 = 310 K.
