Robert Boyle pom PV = ib qho tsis tu ncua. Ntawd yog, cov khoom ntawm lub siab ntawm cov roj lub sij hawm lub ntim ntawm cov pa roj yog acconstant rau ib qho piv txwv ntawm cov roj. Hauv Boyle qhov kev sim ntsuas kub (T) tsis hloov, thiab tsis muaj pes tsawg tus moles (n) ofgas tam sim no.
Raws li, PV ua haujlwm chemistry yog dab tsi?
PV ua haujlwm yog ib lub ntsiab lus tseem ceeb hauv chemicalthermodynamics . txhais cov ua haujlwm ua los ntawm qhov systemthaum tag nrho cov txheej txheem thim rov qab. Thawj txoj cai ntawm thermodynamics tuaj yeem qhia raws li. (Nyob rau hauv lub rooj sib tham lwm qhov chaw uas W = ua haujlwm ua tiav ntawm qhov system,.
Kuj Paub, PV hauv enthalpy yog dab tsi? Zog thiab Enthalpy Cov yog ntsuas kub hauv qhov system. Lawv siv cov mis H = U + PV . H yog enthalpy tus nqi, U yog tus nqi ntawm lub zog sab hauv, thiab P thiab V yog lub zog thiab ntim ntawm qhov system.
Kuj tseem paub yog, PV nRT sawv cev rau dab tsi?
n. Ib txoj cai ntawm lub cev piav txog kev sib raug zoo ntawm cov khoom siv ntsuas tau ntawm cov roj zoo tagnrho, qhov twg P (siab) × V (ntim) = n (number of moles) × R (cov pa tsis tu ncua) × T (kub hauv Kelvin). Nws yog muab los ntawm kev sib xyaw ua ke ntawm thegas txoj cai ntawm Boyle, Charles, thiab Avogadro. Kuj hu ua universal gaslaw.
3 gas laws yog dab tsi?
Cov peb tsim nyog gas laws nrhiav kev sib raug zoo ntawm lub siab, kub, ntim thiab tus nqi ntawm gas . Boyle cov Txoj cai qhia peb tias qhov ntim ntawm gas nce thaum lub siab txo. Qhov zoo tagnrho gaslaw yog qhov sib xyaw ntawm cov peb yooj yim gaslaws.

Dab tsi yog qhov txawv ntawm cov chemistry thiab organic chemistry?
Organic chemistry yog suav tias yog ib qho kev qhia ntawm chemistry. Thaum lub sij hawm lub kaus dav dav 'chemistry' yog kev txhawj xeeb nrog kev sib xyaw thiab kev hloov pauv ntawm txhua yam teeb meem, cov khoom siv tshuaj lom neeg tsuas yog txwv rau kev kawm ntawm cov organic tebchaw xwb
John Dalton qhov kev ua tiav tseem ceeb hauv chemistry yog dab tsi?
John Dalton FRS (/ˈd?ːlt?n/; 6 Cuaj hlis 1766 – 27 Lub Xya hli ntuj 1844) yog ib tug Askiv chemist, physicist, thiab meteorologist. Nws paub zoo tshaj plaws rau kev qhia txog atomic txoj kev xav rau hauv chemistry, thiab rau nws txoj kev tshawb fawb rau hauv qhov muag tsis pom xim, qee zaum hu ua Daltonism hauv nws txoj kev hwm
Hooke's Law hauv chemistry yog dab tsi?
CHEMISTRY GLOSSARY Hooke txoj cai hais tias lub cev deformation yog proportional rau qhov loj ntawm deforming quab yuam, muab hais tias lub cev elasticity (saib elasticity) tsis tshaj. Yog tias qhov txwv tsis pub ncav cuag, lub cev yuav rov qab mus rau nws qhov qub qub thaum lub zog raug tshem tawm
Dab tsi yog txoj cai cais tawm hauv chemistry?
Pauli Exclusion Principle hais tias, hauv anatom lossis molecule, tsis muaj ob lub tshuab hluav taws xob tuaj yeem muaj tib tus lej plaub hauv quantum. Raws li lub orbital tuaj yeem muaj qhov siab tshaj plaws ntawm ob lub electrons, ob lub electrons yuav tsum muaj opposingspins
Dab tsi yog equilibrium hauv chemistry GCSE?
Equilibria. Qhov GCSE Chemistry Quiz no yog txhua yam hais txog kev sib npaug. Lo lus equilibrium txhais tau hais tias ib yam dab tsi nyob rau hauv lub xeev ntawm kev sib npaug. Hauv chemistry, nws hais txog qhov xwm txheej uas qhov concentrations ntawm cov reactants thiab cov khoom yog tas li
