Nyob rau hauv solidification, tshav kub zog yog liberated.

Yuav ua li cas rau thermal zog hauv cov txheej txheem ntawm solidification?

Cov khoom--kua interface nthuav tawm rau hauv cov kua; Thaum tshav kub kub tso tawm los ntawm cov txheej txheem solidification yog nqa hla cov khoom ntawm conductionYog tias cov kua nyob deb tshaj qhov txias txias lossis fusion point, cua sov yog thauj los ntawm cov kua mus rau cov khoom txav-kua sib txuas los ntawm convection thiab conduction.

Yuav ua li cas thiaj ua tau kom khov kho?

Solidification yog txheej txheem ntawm kev hloov pauv ntawm cov kua rau ib qho khoom…Rau cov ntaub ntawv uas cov khoom crystalline theem tsis nucleate hauv cov txheej txheem txias, cov qauv iav yog tsim.

Puas solidification tso thermal zog?

Thaum solidification, heat is release, uas yog hu ua cua sov ntawm crystallization los yog kub ntawm solidification. Nws tiv thaiv qhov txias sab nraud.

Lub npe ntawm lub zog tso tawm thaum lub sijhawm ua haujlwm khov kho yog dab tsi?

Nyob rau hauv qhov no, lub zog cua sov yuav tsum tau muab tawm thaum lub sij hawm solidification ntawm cov kua yog hu ua heat of solidification Txawm tias thaum tshav kub ntawm solidification raug tso tawm, qhov kub thiab txias tseem nyob. tas li. Nws tsuas yog poob thaum cov khoom ua kua tau ua tiav tiav.
