Txoj cai gas zoo tagnrho yog: pV ua = nRT , qhov twg n yog tus naj npawb ntawm moles, thiab R yog universal gas tas li.
Hais txog qhov no, R txhais li cas hauv txoj cai roj zoo?
R hais txog ' zoo tagnrho gas tas li' hauv J K^-1 mol^-1. Qhov no yog qhov kom muaj nuj nqis uas txuas cov kev sib raug zoo ntawm lub siab (P), kub (T), tus naj npawb ntawm moles (n) thiab ntim (V) rau ib qho zoo tagnrho gas . P thiab V yog inversely proportional, thiab P thiab T yog ncaj qha proportional.
PV sib npaug rau nRT yog dab tsi? Ntawm qhov kub thiab txias tas li, qhov ntim ntawm cov roj yog ncaj qha proportional rau cov roj moles. Ntawm qhov kub thiab txias tas li, lub siab ntawm cov pa roj yog ncaj qha proportional rau cov roj moles. Los yog koj tuaj yeem xav txog qhov teeb meem me ntsis thiab siv PV = nRT . N2O yog muab tso rau hauv lub piston.
Kuj nug, dab tsi yog r hauv PV nRT rau mmHg?
Tus nqi ntawm cov pa tsis tu ncua ' R ' nyob ntawm cov units siv rau siab, ntim thiab kub. R = 0.0821 litre·atm/mol·K. R = 8.3145 J/mol·K. R Luas = 8.2057 m3· atm/mol · K. R = 62,3637 L· Torr /mol·K lossis L· mmHg /mol·K.
Tus nqi ntawm R yog dab tsi?
Gas tsis tu ncua R yog 8.314 J / mol. · K. Hloov cov lej tus nqi ntawm R kom nws cov units yog cal / (mol. · K).

C sawv cev rau dab tsi hauv daim qauv?
Standard Form: daim ntawv qauv ntawm ib kab yog nyob rau hauv daim ntawv Ax + By = C qhov twg A yog ib tug zoo integer, thiab B, thiab C yog integers
KVp sawv cev rau dab tsi hauv hluav taws xob?
Dr Francis Deng thiab Dr Ayush Goel et al. Kilovoltage ncov (kVp) yog lub siab tshaj plaws muaj peev xwm siv rau lub x-ray raj, uas ua kom cov electrons los ntawm cathode mus rau anode hauv radiography lossis xam tomography. Tube voltage, nyob rau hauv lem, txiav txim qhov ntau thiab zoo ntawm cov photons generated
Dab tsi cov tshuaj tiv thaiv sawv cev rau lub cev qhuav dej synthesis?
Nyob rau hauv lub cev qhuav dej synthesis cov tshuaj tiv thaiv (Daim duab), cov hydrogen ntawm ib tug monomer ua ke nrog cov hydroxyl pawg ntawm lwm monomer, tso ib tug molecule ntawm dej. Nyob rau tib lub sijhawm, cov monomers sib koom electrons thiab tsim covalent bonds. Raws li cov monomers ntxiv koom nrog, cov saw hlau ntawm kev rov ua dua monomers tsim ib lub polymer
SFA sawv cev rau dab tsi ntawm lub cev muaj zog?
Service Factor Amps, los yog S.F.A., sawv cev rau tus nqi tam sim no lub cev muaj zog yuav kos thaum khiav ntawm tag nrho Service Factor. Hauv qhov piv txwv nameplate, S.F.A. yog yim amps ntawm 230 volts. Txuas ntxiv tshaj S.F.A. qhia rau ntawm daim ntawv teev npe tuaj yeem ua lub neej luv luv
Qhov twg electron configuration sawv cev rau ib tug atom nyob rau hauv nws lub hauv av?
Yog li txhua qhov kev teeb tsa hluav taws xob nyob rau hauv uas lub xeem electron (dua, lub valence electron) yog nyob rau hauv lub zog ntau dua orbital, lub caij no tau hais tias nyob rau hauv lub xeev zoo siab. Piv txwv li, yog tias peb saib hauv av hauv lub xeev (electrons nyob rau hauv lub zog qis tshaj plaws uas muaj orbital) ntawm oxygen, lub teeb tsa hluav taws xob yog 1s22s22p4
