Ua rau ntawm supercooled kua
Thaum lub sij hawm peb npaug ntawm cov khoom ntshiab, qhov siab ntawm vapor siab ntawm cov kua yog sib npaug ntawm qhov siab ntawm vapor siab ntawm cov khoom. Siab vapor siab. Yog li no, ntawm qhov ntsuas kub no, cov khoom siv hluav taws xob tsis tuaj yeem yog tias lub pob zeb me me tau muab tso ua ke nrog cov kua. Tsuas yog thaum ntsuas kub tsawg dua rau qee qhov kub ntawm qhov uas lub voos txaus vapor siab ntawm cov kua yog sib npaug ntawm qhov siab ntawm vapor siab ntawm lub pob me me, nws yog qhov ua tau kom tshem tau Cov Khoom Tsim muaj cov kua me me. Qhov no yog vim li cas kua dej supercooled tshwm sim. Supercooled kua yog lub xeev tsis ruaj khov metastable.
