Ntawm no, nyob rau theem S twg yog cov molecules tuav nyob rau hauv cov duab meej?

Khoom

Ib yam li ntawd, qhov kub thiab txias cuam tshuam li cas rau theem hloov? Cov cua sov yog siv los rhuav tshem cov kev sib txuas ntawm cov dej khov molecules thaum lawv tig mus ua kua theem . Txij li qhov nruab nrab kinetic zog ntawm cov molecules tsis hloov thaum lub sij hawm melting, lub kub ntawm cov molecules tsis hloov.

Tsuas yog, ntawm qhov kub npaum li cas dej yuav hloov ntawm cov kua mus rau qhov khov khov?

Supercooling yog cov txheej txheem ntawm kev txo qhov kub ntawm cov kua los yog roj hauv qab nws qhov chaw khov yam tsis tau ua ib qho khoom (raws li hauv coke tricks qhia hauv video). Thaum cov kua nce mus txog nws qhov chaw khov kho (feem ntau yog 0 degrees Celsius rau dej) nws yuav crystalize thiab ua ib qho khoom.

Vim li cas cov kev hloov pauv tshwm sim?

Qauv teb: Kev hloov theem tshwm sim vim lub zog ntawm molecular zog. Raws li cua sov yog ntxiv rau cov khoom, cov molecules tawg tawm ntawm lawv cov ntawv cog lus thiab pib txav mus los ywj pheej, ua rau cov khoom tawg. Raws li cua sov yog ntxiv rau cov kua, cov molecules txav nrawm dua thiab nrawm dua kom txog thaum lawv tawg tsis muaj kua thiab dhau los ua roj.
