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.
