hluav taws xob hluav taws xob qauv
Qhov tshwm sim ntawm cov hluav taws xob tsis muaj hluav taws xob tsim los ntawm cov kev sib tham sib hloov ntawm hluav taws xob thiab sib nqus. Qhov tshwm sim uas cov xaim hluav taws xob tau tsim tawm los yog laim rau saum huab cua yog hu ua electromagnetic hluav taws xob. Cov hluav taws xob hluav taws xob yog qhov chaw tsis pom thiab tsis paub tab. Lub ntiaj teb uas tib neeg nyob yog ib qho chaw muaj zog loj heev. Ob lub thermal hluav taws xob thiab xob laim ntawm nws saum npoo tuaj yeem tsim hluav taws xob hluav taws xob. Lub hnub thiab lwm lub ntiaj teb kuj txuas ntxiv tsim hluav taws xob hauv hluav taws xob los ntawm qhov chaw sab nraud. Ntuj sib nqus laim nyob ib puag ncig ntawm tib neeg lub cev, hnub ci, khoom siv hauv tsev, thiab lwm yam tawm ntawm hluav taws xob nrog kev sib zog sib txawv. Hluav taws xob hluav taws xob yog qhov kev tawm tsam sab nraud ntawm kev txav ntawm atoms thiab molecules hauv ib yam khoom.
