Txhua lub zog molecular nres ntawm 0 degrees Kelvin degrees Kelvin Lub Kelvin nplai ua tiav Thomson cov kev xav tau raws li qhov ntsuas kub tsis txaus Nws siv xoom xoom raws li nws qhov tsis muaj qhov taw tes (piv txwv li qis entropy). Kev sib txheeb ntawm kelvin thiab Celsius ntsuas yog TK=t°C + 273.15. Ntawm Kelvin nplai, dej ntshiab khov ntawm 273.15 K, thiab nws boils ntawm 373.15 K hauv 1 atm. https://en.wikipedia.org › wiki › Kelvin

lossis -273.15 degrees Celsius.
Dab tsi yog molecular motion nres ntawm?
Ib qhov ntsuas kub uas nws xoom taw tes yog xoom xoom, qhov kub ntawm 0 entropy ntawm txhua qhov kev txav ntawm molecular nres, - 273.15 ° C. Qhov loj ntawm ib degree Kelvin yog qhov tib yam li qhov loj ntawm ib degree Celsius.
Muaj molecular motion nres?
Puas molecules nres txav ntawm qhov xoom? Teb 1: Cov lus teb ceev ceev rau koj cov lus nug tsis yog, molecules tsis txhob txav ntawm qhov xoom. Lawv txav tsawg dua ntawm qhov kub siab dua, tab sis lawv tseem muaj kev vibration me me ntawm xoom xoom.
Yuav ua li cas thaum molecular motion nres?
Kelvin Scale
Nws yog raws li cov lus tsa suab molecular, nrog qhov kub ntawm 0K, tseem hu ua xoom xoom, yog lub ntsiab lus uas txhua qhov kev txav ntawm molecular tso tseg. Qhov dej khov ntawm cov dej ntawm Kelvin nplai yog 273.15K, thaum qhov kub kub yog 373.15K.
nws hu li cas thaum molecules kiag li nres?
Thaum tag nrho cov molecules (los yog atoms) nyob rau hauv ib qho system nres txav kiag li, qhov ntawd txias npaum li lawv tuaj yeem tau. Qhov kub no, qhov twg tsis muaj thermal zog tag nrho, yog hu ua tsis muaj xoom. Tus lej, qhov no yog sau ua 0 K, -273.15 ° C, lossis -459.67 ° F.
