Vim tias Rankine degree yog tib qhov loj li qhov Fahrenheit degree, qhov dej khov dej (32 ° C) thiab dej kub npau npau (212 ° C) sib xws 491.67° Ra thiab 671.67 ° Ra, feem.

Kuj paub yog, qhov Rankine ntsuas kub siv nyob qhov twg?

Rankine feem ntau siv hauv kev lag luam aerospace hauv Tebchaws Meskas. Rankine yog rau Fahrenheit dab tsi Kelvin yog rau Celsius. Yog li thaum cov neeg hauv Tebchaws Meskas tau tsim cov kev pabcuam thiab siv qhov sib npaug uas xav tau qhov tseeb kub , lawv siv Rankine ua ntej Celsius dhau los ua tus thawj rau kev suav lej.

Ib sab saum toj no, dab tsi yog qhov chaw khov thiab dej kub ntawm qhov ntsuas Celsius? Cov Fahrenheit nplai txhais cov qhov chaw khov dej li 32 ° F thiab kub point 212 ° F. Cov Celsius teev teev cov freezing point thiab boiling point ntawm dej ntawm 0 ° C thiab 100 ° C feem.

Hais txog qhov no, dej kub dab tsi hauv Fahrenheit Celsius thiab Kelvin?

Cov boiling qhov chaw dej hauv Celsius , Fahrenheit thiab Kelvin nplai yog 100 degree Celsius (los yog C), 212 degree Fahrenheit (los yog F) thiab 373 Kelvin (lossis K).

Puas yog Rankin ntsuas qhov ntsuas kub?

n/) yog qhov tseeb nplai ntawm thermodynamic kub muaj npe tom qab Glasgow University tus kws tsim txuj ci thiab kws paub txog lub cev William John Macquorn Rankine, uas tau thov nws xyoo 1859. Yog li, kub ntawm 0 K (−273.15 ° C; −459.67 ° F) yog sib npaug rau 0 ° R, thiab a kub ntawm −458.67 ° F sib npaug rau 1 ° R.
