Ib zoo tagnrho gas yog ib tug hypothetical gas npau suav los ntawm chemists thiab cov tub ntxhais kawm vim hais tias nws yuav yooj yim dua yog tias tej yam xws li intermolecular rog tsis muaj los ua kom nyuaj rau qhov yooj yim. Ideal Gas Law . Zoo tagnrho roj yog qhov tseem ceeb point masses txav mus tas li, random, ncaj-line motion.
Kuj paub, dab tsi yog qhov zoo tagnrho roj hauv chemistry?
Ib zoo tagnrho gas yog a gas nws lub siab P, ntim V, thiab kub T yog cuam tshuam los ntawm zoo tagnrho gas law: PV = nRT. qhov twg n yog tus naj npawb ntawm moles ntawm lub gas thiab R yog zoo tagnrho gas tas li. Zoo tagnrho roj txhais tau tias muaj cov molecules ntawm qhov loj me me nrog qhov nruab nrab molar kinetic zog nyob ntawm qhov kub thiab txias.
Ib yam li ntawd, dab tsi yog hu ua zoo tagnrho gas? Ib zoo tagnrho gas yog qhov theoretical gas tsim los ntawm ntau randomly txav taw tes hais uas nws tsuas yog kev sib tshuam yog zoo kawg nkaus elastic kev sib tsoo. Cov zoo tagnrho gas tswvyim yog pab tau vim nws ua raws li zoo tagnrho gas txoj cai lij choj, ib qho yooj yim sib npaug ntawm lub xeev, thiab yog amenable rau tsom xam raws li statistical mechanics.
Tsis tas li ntawd kom paub yog, dab tsi yog txoj cai roj zoo tagnrho siv rau?
Cov txoj cai gas zoo tagnrho hais txog plaub qhov kev ywj pheej ntawm lub cev ntawm a gas thaum twg los tau. Cov txoj cai gas zoo tagnrho tuaj yeem yog siv hauv cov teeb meem stoichiometry uas muaj tshuaj lom neeg muaj feem cuam tshuam cov pa . Standard kub thiab siab (STP) yog ib qho tseem ceeb ntawm cov txheej txheem benchmark piv rau lwm yam khoom ntawm cov pa.
Puas yog hydrogen yog cov roj zoo tagnrho?
Hydrogen gas cov khoom tuaj yeem kwv yees ncaj ncees raug siv cov IDEAL GAS Kev sib npaug PV = nRT vim tias nws muaj qhov sib xyaw ua ke tsis tshua muaj zog thiab cov molecules tsawg heev. MAS, ib IDEAL gas muaj xoom intermolecular rog thiab xoom molecular ntim yog li Hydrogen tsis yog ib zoo tagnrho gas . Nco ntsoov tsis muaj dab tsi yog ib qho zoo tagnrho gas.

Yuav ua li cas koj daws qhov zoo tagnrho gas txoj cai?
Txoj Cai Kev Cai Roj Hmab Zoo Tshaj Plaws Cov Lus Nug Gas Txoj Cai Cov Lus Nug: Teb: Qhov Volume yog V = 890.0mL thiab qhov kub yog T = 21 ° C thiab qhov siab yog P = 750mmHg. PV = nRT. Teb: Tus naj npawb ntawm moles yog n = 3.00moles, kub yog T = 24 ° C thiab siab yog P = 762.4 mmHg. PV = nRT
Dab tsi yog qhov txawv ntawm txoj cai khoom thiab txoj cai saw?
Peb siv txoj cai saw thaum sib txawv ntawm 'kev ua haujlwm ntawm kev ua haujlwm', zoo li f(g(x)) feem ntau. Peb siv txoj cai khoom thaum sib txawv ntawm ob txoj haujlwm sib npaug ua ke, zoo li f(x)g(x) feem ntau. Tab sis nco ntsoov lawv yog cov haujlwm cais: ib tus tsis vam khom rau cov lus teb rau lwm tus
Dab tsi yog txoj kev pub dawb rau cov molecules hauv cov roj zoo tagnrho?
Hauv cov pa roj, cov molecules sib tsoo nrog ib leeg. Momentum thiab lub zog tau txais kev cawmdim hauv cov kev sib tsoo no, yog li txoj cai roj zoo tagnrho tseem siv tau. Qhov txhais tau tias dawb txoj kev λ yog qhov nruab nrab ntawm qhov kev ncua deb ib qho kev mus los ntawm kev sib tsoo. Yog hais tias 2 hais, txhua lub vojvoog R, tuaj nyob rau hauv 2R ntawm ib leeg, ces lawv sib tsoo
Lub tswv yim ntawm cov roj zoo tagnrho yog dab tsi?
Ideal Gas Law. Ib qho roj zoo tagnrho txhais tau tias yog ib qho uas txhua qhov kev sib tsoo ntawm cov atoms lossis cov molecules zoo kawg nkaus eleastic thiab uas tsis muaj qhov cuam tshuam rau lub zog. Ib tug tuaj yeem pom nws raws li ib qho kev sau ntawm cov spheres zoo kawg nkaus uas sib tsoo tab sis uas tsis muaj kev cuam tshuam nrog ib leeg
Cov roj twg coj zoo tshaj plaws zoo li cov pa roj zoo?
helium Raws li txoj cai, koj ua li cas txiav txim siab seb cov roj twg coj zoo tshaj plaws? Feem ntau, a gas coj mas zoo li ib zoo tagnrho gas ntawm qhov kub siab dua thiab qis dua, vim tias lub zog muaj peev xwm vim muaj zog intermolecular ua tsawg dua piv nrog cov khoom 'kinetic zog, thiab qhov loj ntawm cov molecules yuav tsawg dua piv rau qhov khoob ntawm lawv.
