Thermal expansion tshwm sim thaum ib yam khoom nthuav lossis loj dua vim nws qhov kub thiab txias. Thermal expansion tshwm sim vim rhuab molecules txav sai dua thiab siv ntau qhov chaw.

Yuav ua li cas thermal expansion tsim?

Thermal expansion is the ntxhais ntawm teeb meem hloov pauv hauv ntim teb rau qhov kev hloov pauv ntawm qhov kub. (Ib qho piv txwv ntawm qhov no yog buckling ntawm txoj kev tsheb ciav hlau, raws li pom nyob rau hauv.) Atoms thiab molecules nyob rau hauv ib tug khoom, piv txwv li, tas li oscillate nyob ib ncig ntawm nws equilibrium point. Qhov kev zoo siab no yog hu ua thermal motion.

Dab tsi tshwm sim thermal expansion?

Thermal expansion, qhov dav dav hauv qhov ntim ntawm cov khoom raws li nws qhov kub thiab txias tau nce. … Yog hais tias nws tsis yog isometric, tej zaum yuav muaj sib txawv expansion coefficients rau txawv crystallographic cov lus qhia, thiab cov siv lead ua yuav hloov zoo li kub hloov.

2 piv txwv ntawm thermal expansion yog dab tsi?

Cov piv txwv thermal expansion

  • Kev sib tsoo ntawm txoj kev thaum txoj kev nthuav dav cua sov.
  • Sags hauv cov kab hluav taws xob.
  • Windows ntawm hlau-thav duab xav tau roj hmab spacers kom tsis txhob thermal expansion.
  • Kev sib koom ua ke (xws li kev sib koom ua ke ntawm ob txoj kev tsheb ciav hlau).
  • Qhov ntev ntawm cov hlau bar tau ntev dua rau cua sov.

Puas yog thermal expansion tseem ceeb?

Kev nthuav dav cua sov yog qhov tseem ceeb rau kev tsim vaj tsev vim cov ntaub ntawv sib txawv pom qhov hloov pauv loj thaum raug tshav kub. Yog li, cuam tshuam rau qhov ntev, dav, thaj chaw saum npoo, ntim, thiab lwm yam.
