Thaum cov txheej txheem ntawm melting, evaporation, thiab sublimation, dej absorbs zog. … Thaum lub sij hawm cov txheej txheem ntawm condensation, khov, thiab deposition, dej tso lub zog Lub zog tso tawm tso cai rau cov dej molecules hloov lawv cov qauv kev sib txuas thiab hloov mus rau lub zog qis dua.
Puas tso ntxiv lossis tshem tawm cua sov?
Kev tso tawm yog qhov hloov pauv ntawm lub xeev ntawm cov roj mus rau ib qho khoom yam tsis tau mus dhau lub xeev cov kua. Rau kev tso tawm kom tshwm sim, lub zog cua sov yuav tsum raug tshem tawm ntawm cov pa roj.
txheej txheem dab tsi nqus cua sov?
Ib qho txheej txheem endothermicnqus cua sov thiab ua kom txias ib puag ncig. "
Yog sublimation tso tawm lossis nqus cua sov?
Sublimation yog qhov kev hloov pauv ncaj qha los ntawm lub xeev mus rau vapor, thiab heat absorbedlos ntawm nws yog sib npaug ntawm cov latent heats ntawm fusion thiab vaporization.
Puas yog Fusion yog ib qho kev tawm tsam sab nraud?
Lub fusion ntawm sib zog nuclei, uas tsim ib tug hnyav nucleus thiab feem ntau ib tug dawb neutron los yog proton, feem ntau tso tawm ntau zog tshaj nws yuav siv sij hawm los yuam cov nuclei ua ke; qhov no yog txheej txheem exothermicuas tuaj yeem tsim cov tshuaj tiv thaiv tus kheej.
