Muab nws yooj yim, yog tias koj kub ib yam khoom (xws li ntsev ) txoj kev dhau qhov kub ntawm cov dej kub npau npau, Leidenfrost Effect tuaj yeem tshwm sim thiab ua rau qhov hu ua qhov tawg tawg. Ib zaug lub ntsev yog nchuav rau hauv dej, lub vapor ncig lub ntsev ua superheated, ua rau nce siab.
Cia li xav txog qhov no, yuav ua li cas tshwm sim thaum ntsev ntau dua?
Thaum twg nquag ntsev yog rhuab cov dawb crystalline khoom lub zog tseem zoo li nws yog. Ntsev hmoov (khoom) tsis ua hluav taws xob. Tab sis qhov kub thiab txias yog ze li ntawm 800 degrees. C, ua ntsev reddens thiab melts rau hauv ib lub kua.
ntsev yaj los yog hlawv? Qee cov hlau, zoo li tin, ua ua rau me me tawg, tab sis qhov ntawd yog vim lawv yaj point yog tsawg heev (231.9 degrees Celsius). Tab sis ntsev melts nyob ib ncig ntawm 800 degrees Celsius - yuav luag 200 degrees siab tshaj txhuas - uas txhais tau hais tias nws yuav tsum tau yooj yim kub txaus los ua rau cov nyhuv Leidenfrost.
Tsis tas li lo lus nug yog, ntsev tuaj yeem yaj thaum rhuab?
Ntsev melting point yog 800.8 degrees Celsius, los yog 1473.4 degrees Fahrenheit. Ntawm qhov kub thiab txias, ntsev hloov mus ua kua. Raws li koj ua tau saib, ntsev tau nqus tau ntau heev ntawm kub ua ntej nws dhau mus rau theem hloov, tig los ntawm cov khoom mus rau cov kua thiab los ntawm cov kua rau vapor.
Yuav ua li cas thaum koj microwave ntsev?
Txij li thaum ntsev tsis tuaj yeem nqus cua sov ntau, lub microwave hluav taws xob yuav puas microwave , ua rau nws overheat tom qab ob peb feeb. Tsis tas li ntawd, nws yuav qhuav ntsev . Txij li thaum tag nrho cov dej yuav poob, lub ntsev yuav sau rau hauv cov blocks ntawm ntsev uas nyuaj rau tawg.

Yuav ua li cas thaum lub hydrated ntsev yog rhuab?
Thaum lub hydrate ntsev yog rhuab, cov qauv siv lead ua ntawm cov compound yuav hloov. Ntau hydrates muab loj, zoo tsim muaju. Lawv tuaj yeem tawg thiab tsim cov hmoov raws li cov dej ntawm cov dej ntws tawm. Cov xim ntawm cov khoom sib xyaw kuj tseem tuaj yeem hloov pauv
