Melting point tshwm sim los ntawm ib pawg ntawm kev sim siab yog ib qho piv txwv ntawm qhov kawg
- Blunders ( yuam kev ).
- Tib neeg yuam kev .
- Kev soj ntsuam tus qhov system yuav ua rau yuam kev .
- yuam kev vim muaj kev cuam tshuam sab nraud.
- Tsis yog txhua qhov kev ntsuas muaj qhov ntsuas tau zoo.
- Qauv.
Ib yam li ntawd, qhov piv txwv ntawm kev sim ua yuam kev yog dab tsi?
Rau piv txwv , yuam kev nyob rau hauv kev txiav txim ntawm ib tug neeg soj ntsuam thaum nyeem cov scale ntawm ib tug ntsuas ntsuas mus rau qhov tsawg tshaj plaws faib. 2. Ib puag ncig. Rau piv txwv , unpredictable fluctuations nyob rau hauv kab voltage, kub, los yog mechanical vibrations ntawm cov khoom.
Qhov thib ob, dab tsi yog qhov ua tau ntawm kev sim ua yuam kev? Feem ntau qhov chaw ntawm yuam kev suav nrog instrumental, environmental, procedural, and human. Tag nrho cov no yuam kev tuaj yeem yog random lossis systematic nyob ntawm seb lawv cuam tshuam li cas.
Ntawm no, dab tsi yog qee qhov kev sim ua yuam kev hauv chemistry?
Random yuam kev fluctuation ntawm tus muab lub zog thaum tus siv cov khoom siv hluav taws xob xws li cov khoom siv hluav taws xob. siv cov tshuaj tsis huv hauv ib qho tshwj xeeb kev sim . tus kws sim tau cuam tshuam thaum ntsuas qhov ntsuas.
Qhov kev sim ua yuam kev zoo yog dab tsi?
Engineers kuj yuav tsum tau ceev faj; Txawm hais tias qee qhov kev ntsuas engineering tau ua nrog qhov tseeb zoo (xws li, qhov ceev ntawm lub teeb yog 299, 792, 458 1 m / sec.), rau feem ntau yuam kev tsawg dua 1 feem pua yog xam zoo , thiab rau ob peb tug yuav tsum siv advanced kev sim tsim thiab tsom xam cov txheej txheem kom tau ib yam

Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Dab tsi yog qhov kev ua yuam kev hauv kev sim nrog cov hluav taws xob tam sim no?
Cov peev txheej ntawm kev ua yuam kev suav nrog cov cuab yeej, ib puag ncig, txheej txheem, thiab tib neeg. Tag nrho cov kev ua yuam kev no tuaj yeem ua tsis tau lossis ua haujlwm nyob ntawm seb lawv cuam tshuam li cas. Instrumental yuam kev tshwm sim thaum cov cuab yeej siv tsis raug, xws li qhov sib npaug uas tsis ua haujlwm (SF Fig
Dab tsi yog qhov yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
