Ntawm zero kelvin zero kelvin Tsis muaj xoom xoom yog qhov qis tshaj qhov ua tau kub qhov twg tsis muaj dab tsi tuaj yeem txias dua thiab tsis muaj cua sov nyob hauv cov khoom. … Los ntawm kev pom zoo thoob ntiaj teb, tus lej xoom raug txhais raws li qhov tseeb; 0 K ntawm Kelvin nplai, uas yog qhov ntsuas kub ntawm qhov ntsuas kub (qhov tseeb); thiab -273.15 degrees Celsius ntawm qhov ntsuas Celsius. https://www.sciencedaily.com › lus › absolute_zero
Zoo xoom - ScienceDaily
(rho tawm 273 degrees Celsius) cov khoom tsis txav thiab txhua yam teeb meem ploj mus. … Ntawm qhov ntsuas kub tsis txaus, uas yog siv los ntawm physicists thiab tseem hu ua Kelvin scale Kelvin scale Lub Kelvin nplai ua tiav Thomson cov cai raws li qhov ntsuas kub tsis txaus ntsuas. Nws siv kiag li xoom raws li nws qhov null point (piv txwv li qis entropy). Kev sib txheeb ntawm kelvin thiab Celsius ntsuas yog T K=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

nws tsis tuaj yeem mus qis dua xoom - yam tsawg kawg tsis nyob hauv kev nkag siab tias txias dua xoom kelvin.
Koj puas tuaj yeem tau txais cov khoom kom tsis txhob txav?
Tsis muaj xoom xoom yog qhov ntsuas kub uas cov khoom ntawm cov khoom (molecules thiab atoms) nyob ntawm lawv cov ntsiab lus qis zog. Qee tus yuav xav tias ntawm qhov tsis muaj pes tsawg qhov poob tag nrho lub zog thiab nrestxav mus. … Yog li ntawd, ib qho tsis tuaj yeem nres tau kiag livim tias nws txoj haujlwm thiab lub zog yuav raug paub.
Puas cov khoom tsis txav thaum lawv khov?
Rau cov tshuaj ntshiab, qhov kub ntawm qhov kev hloov pauv no tshwm sim yog qhov tseeb thiab hu ua qhov melting point ntawm cov khoom. Kev khov yog tshwm sim thaum cov kua txias thiab tig mus rau ib qho khoom. … Yog cov roj txias, nws cov khoom yuav tsum tsis txhob txav mus sai heev thiab tsim cov kua.
Puas 0 Kelvin tau mus txog?
Tsis muaj dab tsi hauv lub qab ntuj khwb - lossis hauv chav kuaj - tau mus txog tsis muaj tseeb raws li peb paub. Txawm qhov chaw muaj qhov kub thiab txias ntawm 2.7 kelvins. Tab sis tam sim no peb muaj tus lej tseeb rau nws: -459.67 Fahrenheit, lossis -273.15 degrees Celsius, ob qho tib si sib npaug 0 kelvin.
Can molecules tseem vibrate ntawm qhov xoom?
Piv txwv li, tag nrho cov molecular motion tsis tas ntawm qhov xoom(molecules vibrate nrog qhov hu ua xoom-point zog), tab sis tsis muaj zog los ntawm molecular motion (uas yog, Thaum tshav kub kub lub zog) muaj rau kev hloov mus rau lwm lub tshuab, thiab nws yog vim li no hais tias lub zog ntawm qhov tsis muaj pes tsawg yog tsawg.
