Thaum twg kub yog ntxiv rau ib yam khoom, lub molecules thiab atoms vibrate sai dua. Raws li atoms vibrate sai, qhov chaw nruab nrab ntawm atoms nce. Qhov kev txav thiab qhov sib txawv ntawm qhov cov khoom txiav txim lub xeev ntawm qhov teeb meem ntawm cov khoom. Qhov kawg tshwm sim ntawm kev nce molecular zog yog tias cov khoom nthuav thiab siv nce chaw ntau dua.

Hais txog qhov no, vim li cas cov ntaub ntawv nthuav dav thaum rhuab?

Thaum a khoom yog cua sov , lub zog kinetic ntawm qhov ntawd khoom nce thiab nws cov atoms thiab molecules txav mus txog ntau dua. Qhov no txhais tau hais tias txhua lub atom yuav siv ntau qhov chaw vim nws lub zog yog li qhov khoom yuav nthuav.

Ib yam li ntawd, qhov kub thiab txias cuam tshuam li cas ntawm cov lus tsa suab? Piav: Yog tias kub yog nce lub cov khoom nce kinetic zog ntau dua los yog vibrate sai. Qhov no txhais tau tias lawv txav nrawm dua thiab siv ntau qhov chaw. Cov khoom txav qeeb, vim tsis muaj zog.

Ib yam li ntawd, vim li cas cov particles qeeb qeeb thaum txias?

Thaum ib qho piv txwv ntawm cov khoom, kua, los yog gas teeb meem txias cia , nws cog lus. Thaum tseem ceeb txias cia , nws cov khoom poob kinetic zog. Cov txo kinetic zog cia cov particle los ze zog ua ke. Qhov no ua rau tus teeb meem rau daim ntawv cog lus.

Peb ntsuas kub li cas?

Kub yog ntsuas nyob rau hauv ntau npaum li cas hu ua joules (hais tib yam li jewels) nyob rau hauv lub metric system thiab nyob rau hauv British Thermal Units (BTU) nyob rau hauv lus Askiv system. Kub tuaj yeem yog ntsuas hauv calories. Lub tsev Joule muaj npe tom qab Askiv tus kws kho mob James Prescott Joule (1818 - 1889).
