Cov kua dej supercooled nce hauv qhov kub thiab txias thaum cov txheej txheem ntawm khov pib, vim tias nyob rau hauv cov txheej txheem ntawm kev hloov ntawm lub xeev los ntawm cov khoom mus rau lub xeev cov ntaub ntawv muab tawm nws latent cua sov. Qhov no latent cua sov ua rau kom qhov kub thiab txias ntawm cov khoom. Peb tuaj yeem hais tias txheej txheem no kuj yog txheej txheem exothermic.
Vim li cas cov kua supercooled nce hauv qhov kub thiab txias thaum nws pib khov?
Thaum dej khov ib txwm, piv txwv li mus los ntawm 0 deg C kua mus rau 0 deg C khoom, nws tso tawm ntau lub zog, ua rau nws ib puag ncig siab dua hauv kub tshaj qhov lawv xav tau.
Thaum cov kua txias txias qhov txias txias?
Thaum cov kua dej txias rau nws qhov chaw khov, nws hloov mus rau nws lub xeev khov. Cov txheej txheem no cuam tshuam txog kev poob ntawm lub zog hauv daim ntawv ntawm tshav kub.
Yuav ua li cas thaum cov dej txias txias txias?
Cov kws tshawb fawb hu qhov tshwm sim no supercooling. Supercooled dej yog qhov tsis ruaj khov heev. Jostle nws, thiab tam sim ntawd nws freezes. Phau nws mus rau saum npoo, thiab nws hloov los ntawm cov kua mus rau dej khov slush.
supercooling cuam tshuam qhov chaw khov li cas?
Supercooling yog cov txheej txheem ua kom txias cov kua lossis roj hauv qab nws qhov chaw khov yam tsis muaj nws ua cov khoom. Thaum nws cov nucleation pib, cov khoom kub nce mus rau nws qhov khov tiag tiag, thiab tom qab ntawd txuas ntxiv khov ntawm qhov kub ntawd. …
