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. Cov tus nqi ntawm R nyob ntawm cov koom haum koom nrog, tab sis feem ntau hais nrog S. I. units xws li: R = 8.314 J/mol·K. Qhov no txhais tau hais tias rau huab cua, koj tuaj yeem siv lub tus nqi R = 287 J/kg · K.
Kuj paub, R sawv cev rau dab tsi hauv PV nRT?
Cov units ntawm universal gas tas li R yog muab los ntawm equation PV = n R T. Nws sawv rauRegnault.
Ib yam li ntawd, tus nqi ntawm R universal gas tas li yog dab tsi? Qhov ntev ntawm cov universal gas tas li R yog lub zog ib degree ib mole. Hauv meter-kilogram-thib ob system, lub tus nqi ntawm R yog 8.3144598 joules per kelvin (K) per mole.
Yog li ntawd, R tus nqi hauv chemistry yog dab tsi?
Cov 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 = 8.3145J/mol·K.
Dab tsi yog qhov tas li R sib npaug hauv PV nRT?
Hauv SI units, P yog ntsuas hauv pascals, V yog ntsuas incubic meters, n yog ntsuas hauv moles, thiab T hauv kelvins (Kelvinscale yog ntsuas ntsuas kub, qhov twg 0.00 K = −273.15 ° C, qhov ntsuas kub qis tshaj). R muaj tus nqi 8.314 J/(K. mol) ≈ 2 cal/(K. mol), los yog 0.08206 L.

Dab tsi yog qhov txawv ntawm ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
A. Ib puag ncig lapse tus nqi yog hais txog qhov kub thiab txias nrog nce qhov siab hauv troposphere; uas yog qhov kub ntawm ib puag ncig ntawm qhov chaw sib txawv. Nws implies tsis muaj huab cua txav. Adiabatic txias tsuas yog cuam tshuam nrog huab cua ascending, uas txias los ntawm kev nthuav dav
Dab tsi yog ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
Recap • Lapse Rate yog tus nqi uas kub qis dua thaum qhov siab nce hauv huab cua • Ib puag ncig lapse tus nqi yog tus nqi uas kub qis dua thaum tus nqi tsis cuam tshuam los ntawm huab cua saturation • Environmental lapse rate txo sai dua thaum huab cua tsis ruaj khov. tsis ruaj khov
Yuav ua li cas koj thiaj nrhiav tau tus nqi ploj ntawm tus nqi tsim?
Tus nqi ntawm ib qho tshuaj tiv thaiv yog qhov kev hloov hauv kev concentration ntawm qhov kev hloov ntawm lub sijhawm. Cov tshuaj tiv thaiv tuaj yeem txhais tau li no: tus nqi ploj ntawm A tus nqi = −Δ [A] Δt. tus nqi ploj ntawm B tus nqi = − Δ [B] Δt. tus nqi tsim ntawm C tus nqi = Δ [C] Δt. tus nqi tsim ntawm D) tus nqi = Δ [D] Δt
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
