npe. ib qho thermodynamic kub nplai raws li kev ua tau zoo ntawm cov tshuab cua sov zoo tagnrho. Zero ntawm nplai yog zero kiag li. Thaum xub thawj qib kawm tau sib npaug rau ntawm Celsius nplai tab sis nws yog tam sim no txhais yog li ntawd peb npaug ntawm cov dej yog raws nraim 273.16 cov leeg.
Ib yam li ntawd, koj yuav nug, Kelvin nplai ua haujlwm li cas?
Kelvin kub nplai , kub nplai muaj qhov tsis muaj pes tsawg hauv qab qhov kub ua tsis muaj nyob. Qhov tsis muaj pes tsawg, lossis 0 ° K, yog qhov ntsuas kub uas lub zog molecular yog qhov tsawg kawg nkaus, thiab nws sib xws rau qhov kub ntawm -273.15 ° ntawm qhov ntsuas kub Celsius nplai.
Kuj Paub, dab tsi yog lub ntsiab lus ntawm 1 Kelvin? Cov kelvin (cov ntawv luv K), tsawg zaus feem ntau hu ua qib Kelvin (cim, o K), yog Tus Txheej Txheem Thoob Ntiaj Teb (SI) chav ntsuas kub. Ib kelvin yog raws cai txhais raws li 1 /273.16 (3.6609 x 10 -3) ntawm qhov ntsuas cua sov ntawm qhov ntsuas peb npaug ntawm cov dej ntshiab (H 2 O).
Ib yam nkaus, vim li cas thiaj muaj qhov ntsuas Kelvin?
Piav qhia: Kelvin nplai pib ntawm zero kiag li. 0 qib Kelvin sawv cev zero kinetic zog los yog kub. Cov kws tshawb fawb siv Kelvin nplai vim nws yog qhov kub thiab txias nplai uas cuam tshuam ncaj qha rau kinetic zog thiab ntim.
Kelvin system yog dab tsi?
Kelvin (K), lub hauv paus ntawm kev ntsuas ntsuas kub hauv lub ntiaj teb Qhov system ntawm Chav Nyob (SI). Chav tsev no tau piav qhia thawj zaug ua 100/27, 316 ntawm peb lub ntsiab lus (sib npaug ntawm cov khoom, ua kua, thiab theem roj cua) ntawm cov dej ntshiab.

Peb sawv cev qhov ntsuas kub hauv Kelvin li cas?
Kelvin ntsuas kub, qhov ntsuas kub uas muaj qhov tsis muaj xoom hauv qab uas kub tsis muaj nyob. Tsis muaj pes tsawg, lossis 0 ° K, yog qhov ntsuas kub uas lub zog molecular yog qhov tsawg kawg nkaus, thiab nws sib xws rau qhov kub ntawm & rho tawm; 273.15 ° ntawm qhov ntsuas kub Celsius
Nws txhais li cas thaum tus neeg tsav tsheb nthuav nws txhais caj npab sab laug?
Nthuav koj sab caj npab tawm ntawm lub qhov rais tsav tsheb thiab taw tes koj txhais caj npab nrog koj cov ntiv tes txuas ntxiv thiab koj xib teg tig rov qab. Nov yog qhov kev lees paub thoob ntiaj teb uas koj tab tom ua kom qeeb, thiab lwm tus neeg tsav tsheb nkag siab nws nkag siab. Khaws koj txhais caj npab nyob rau hauv txoj hauj lwm no tsawg kawg kom txog thaum koj tuaj txog tag nrho
Thaum tus neeg tsav tsheb txhais tes thiab txhais caj npab tau nqis qis dua?
Yog hais tias tus neeg tsav tsheb sab tes thiab txhais tes tau txuas rau hauv qab, lawv qhia tias lawv npaj siab yuav tsum nres. Kho koj txoj kev tsav tsheb kom haum yog ua raws li tus neeg tsav tsheb uas siv lub teeb liab tes no
Koj hloov ntawm Celsius thiab Kelvin li cas?
Koj tuaj yeem hloov ntawm Celsius thiab Kelvin zoo li no: Kelvin = Celsius + 273.15. Feem ntau, tus nqi ntawm 273 yog siv los ntawm 273.15. Nrog koj tus kws qhia ntawv txog qhov no
Vim li cas qhov ntsuas kub ntawm Celsius feem ntau siv ntau dua li Kelvin nplai?
Cov kws tshawb fawb siv qhov ntsuas Celsius rau ob qhov laj thawj tseem ceeb: Hauv Celsius ntsuas qhov txias thiab cov dej kub npau yog 100 units (lossis degrees Celsius) sib nrug, qhov chaw khov yog 0 degrees Celsius thiab cov dej kub tau teev tseg ntawm 100 degrees Celsius. Vim li cas thiaj muaj celcius, Fahrenheit thiab Kelvin nplai?
