Yuav ua li cas yog crystallization ntawm ntsev?
Ntsev yog tau los ntawm evaporation ntawm seawater. Txawm li cas los xij, cov ntsev no tsis huv thiab muaj cov muaju me me. Cov ntsev no tuaj yeem hloov mus rau hauv lub xeev ntshiab los ntawm cov txheej txheem ntawm crystallization. Crystallization yog txheej txheem ntawm kev tsim cov muaju loj hauv lub xeev ntshiab los ntawm lawv cov kev daws.
Puas ntsev crystalize hauv dej?
Thaum koj ntxiv ntsev rau hauv dej, cov muaju yaj thiab cov ntsev nkag mus rau hauv cov tshuaj. Tab sis koj tsis tuaj yeem yaj cov ntsev tsis kawg rau hauv ib lub ntim dej ruaj khov. … Supersaturation yog lub xeev tsis ruaj khov, thiab cov ntsev molecules yuav pib crystallize rov qab mus rau hauv cov khoom.
Koj ua crystallization li cas?
