"Kev hloov hluav taws xob". Cov dej khov qhuav tsoo rau saum npoo yuav tsum tau ntxuav ntawm kev kub ceev, lub zog kinetic ntawm qhov cuam tshuam dissipates, thiab cov dej khov qhuav qhuav thiab qhov chaw ntxuav tau raug hloov pauv sai heev, thiab carbon dioxide sublimates tam sim ntawd.
"Low-temperature cracking". Qhov kub ntawm qhov sib txawv ntawm ob yam khoom sib txawv nrog cov thermal expansion coefficients sib txawv yuav rhuav tshem cov khoom sib txuas ntawm ob cov ntaub ntawv. Cov dej khov qhuav qhuav (-78.5 degree) cuam tshuam rau saum npoo ntawm cov khoom kho, khov cov av kom brittleness thiab bursting, ua rau "kawg" thiab cuam tshuam rau cov khoom siv ntawm cov av nplaum.
"Micro-explosion" Tom qab cov dej khov qhuav qhuav rau hauv cov kab nrib pleb ntawm cov av, lawv vaporize li ob peb txhiab thib ob, thiab lawv lub ntim tam sim ntawd nthuav dav 600-800 zaug, tshem tawm cov av tawm ntawm qhov khoom.
