Condensation yog hloov dej los ntawm nws daim ntawv gaseous (dej vapor) rau hauv cov dej ua kua Condensation feem ntau tshwm sim hauv huab cua thaum huab cua sov nce, txias thiab looses nws lub peev xwm tuav. dej vapor. Yog li ntawd, cov dej vapor ntau dhau los ua cov huab cua.
Yuav ua li cas rau dej condensation?
Condensation yog lo lus rau dej hloov lub xeev ntawm vapor mus rau cov kua. Cov txheej txheem yuav tsum muaj muaj dej vapor nyob rau hauv qhov chaw, poob qhov kub thiab muaj lwm yam khoom rau dej vaporkom condense ib ncig.
condenser Class 9 yog dab tsi?
Thaum ib homogeneous sib tov ntawm cov khoom thiab cov kua yog rhuab nyob rau hauv ib tug kaw distillation fwj, cov kua, ua volatile, forms vapour. Cov vapors ntawm cov kua tau dhau los ntawm "condenser" lossis "Liebig condenser" qhov twg lawv tau txias thiab condense los ua kua ntshiab.
Lub ntsiab lus ntawm condensation hauv physics yog dab tsi?
Condensation yog hloov pauv ntawm lub cev lub cev ntawm cov teeb meem los ntawm theem roj mus rau theem ua kua, thiab yog qhov thim rov qab ntawm vaporization. … Nws kuj tseem tuaj yeem txhais tau tias yog qhov hloov pauv ntawm lub xeev ntawm cov dej vapor mus rau cov dej ua kua thaum sib cuag nrog cov kua lossis cov khoom nto lossis huab condensation nuclei hauv huab cua.
piv txwv ntawm dej condensation yog dab tsi?
Cov piv txwv ntawm cov condensation yog: dew forming on nyom thaum sawv ntxov, qhov muag tsom iav fogging thaum koj nkag mus rau hauv ib lub tsev sov rau lub caij ntuj no txias, los yog dej tee tsim. ntawm ib khob tuav dej txias rau hnub kub lub caij ntuj sov. Condensation tshwm sim thaum cov tee dej tsim vim cua txias.

Ntawm qhov sib npaug ntawm qhov sib npaug ntawm cov reactants) thiab cov khoom) yog qhov tas li?
Nyob rau hauv ib qho tshuaj sib npaug, cov tshuaj tiv thaiv rau pem hauv ntej thiab thim rov qab Cov tshuaj tiv thaiv rov qab yog ib qho reaction uas hloov dua siab tshiab ntawm reactants rau cov khoom thiab hloov cov khoom rau reactants tshwm sim ib txhij … Hauv qhov rov qab cov tshuaj tiv thaiv, hydrogen iodide decomposes rov qab rau hauv hydrogen thiab iodine.
Puas yog piv txwv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob?
Piv txwv rau cov khoom siv tsis ncaj band sib txawv yog silicon (Si), germanium (Ge), aluminium arsenide (AlAs) thiab gallium phosphide (GaP) . Yuav ua li cas piv txwv ntawm indirect band gap? Piv txwv ntawm cov ntaub ntawv ncaj qha muaj xws li amorphous silicon thiab qee cov khoom siv III-V xws li InAs thiab GaAs.
Yog ntsev yog ib qho khoom xyaw lossis sib xyaw?
S alt is lwm compound. Nws cov qauv tshuaj yog NaCl, uas sawv cev rau sodium chloride . Yog ntsev yog ib qho khoom lossis cov khoom sib xyaw? Tshuaj, cov ntsev ntsev muaj ob lub ntsiab lus, sodium (Na) thiab chloride (Cl). Tsis yog lub ntsiab lus tshwm sim sib cais thiab dawb hauv cov xwm txheej, tab sis pom muaj khi ua ke raws li compound sodium chloride .
Rau cov roj zoo tagnrho uas qhov sib txawv yog qhov sib txawv ntawm qhov sib txawv?
Boyle txoj cai hais tias siab (P) thiab ntim (V) yog qhov sib npaug. Charles txoj cai hais tias ntim (V) thiab qhov kub thiab txias (T) ncaj qha proportional . Txoj cai roj twg yog qhov sib npaug sib npaug? Rau qhov loj ntawm cov roj zoo tagnrho khaws cia ntawm qhov kub thiab txias, siab thiab ntim yog qhov sib npaug.
Nyob rau hauv ib qho kev tsis sib haum xeeb pn kev sib tshuam cov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
Nyob rau hauv qhov tsis ncaj ncees PN-kho qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog zero, vim tias sib npaug tab sis cov neeg nqa khoom hla hla kev sib tshuam . Thaum pn kev sib tshuam tsis ncaj ncees qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
