Qhov sib txawv tseem ceeb ntawm cov txheej txheem adiabatic thiab thim rov qab adiabatic yog tias nyob rau hauv cov txheej txheem adiabatic, cov txheej txheem adiabatic yog rwb thaiv tsev thiab tsis tso cai rau kev hloov pauv cua sov, thaum cov txheej txheem thim rov qab adiabatic cuam tshuam nrog kev hloov pauv cua sov uas qhov ntau ntawm cov cua sov hloov mus ncaj qha. mus rau qhov hloov pauv entropy ntawm qhov system.
cov txheej txheem Adiabatic yog cov txheej txheem thermodynamic uas tsis muaj qhov hloov pauv kub tshwm sim vim muaj cov tshuaj tiv thaiv. Cov txheej txheem thim rov qab adiabatic kuj tsis cuam tshuam txog kev hloov hluav taws xob. Ntawm no, lub tshav kub hloov pauv ncaj qha mus rau qhov hloov pauv ntawm entropy ntawm qhov system, thiab qhov hloov pauv entropy yog xoom, uas ua rau lub tshav kub hloov mus rau xoom.
Txheej txheem Adiabatic yog dab tsi?
txheej txheem Adiabatic tuaj yeem txhais tau tias yog kev hloov pauv ntawm lub kaw lus uas tsis muaj cua sov hloov mus rau hauv lossis tawm ntawm lub cev. Feem ntau, lub tshav kub hloov pauv yog nres nyob rau hauv ob txoj kev. Ib txoj hauv kev yog siv cov ciam teb thermally insulated kom tsis muaj cua sov nkag los yog tawm. Piv txwv li, ib qho tshuaj tiv thaiv uas tshwm sim hauv Dewar flask yog adiabatic. Lwm txoj kev uas cov txheej txheem adiabatic tuaj yeem tshwm sim yog thaum cov txheej txheem tshwm sim sai heev; yog li ntawd, tsis muaj sij hawm los hloov cov cua sov hauv thiab tawm.
In thermodynamics, peb qhia qhov hloov pauv ntawm adiabatic los ntawm dQ=0. Hauv cov xwm txheej no, muaj kev sib raug zoo ntawm lub siab thiab qhov kub thiab txias. Yog li ntawd, lub kaw lus tau hloov pauv vim muaj kev ntxhov siab hauv adiabatic mob. Qhov no tshwm sim nyob rau hauv huab tsim thiab loj-scale convectional tam sim no. Ntawm qhov siab dua, muaj qhov qis atmospheric siab. Thaum huab cua sov, nws zoo li nce mus. Vim tias sab nraud huab cua siab tsawg, qhov nce huab cua parcel yuav sim nthuav. Thaum nthuav dav, cov huab cua molecules ua haujlwm, thiab qhov no yuav cuam tshuam rau lawv qhov kub thiab txias. Qhov no yog vim li cas qhov kub thiab txias txo thaum nce.
Raws li cov thermodynamics, lub zog hauv cov pob khoom tseem nyob tas li, tab sis nws tuaj yeem hloov mus ua haujlwm nthuav dav lossis tswj nws qhov kub thiab txias. Tsis muaj kev sib pauv cua sov nrog rau sab nraud. Tib yam tshwm sim no siv rau cua compression, ib yam nkaus (piv txwv li, lub piston). Hauv qhov xwm txheej ntawd, thaum huab cua parcel compresses, kub nce. Cov txheej txheem no hu ua adiabatic cua sov thiab txias.
Dab tsi yog Reversible Adiabatic Process (Isentropic Process)?
Cov txheej txheem adiabatic thim rov qab kuj tseem hu ua txheej txheem isentropic. Cov txheej txheem spontaneous nce lub entropy ntawm lub ntug. Thaum qhov no tshwm sim, txawm tias qhov system entropy lossis ib puag ncig entropy tuaj yeem nce ntxiv. Cov txheej txheem isentropic tshwm sim thaum lub system entropy tseem nyob tas li. Cov txheej txheem thim rov qab adiabatic yog ib qho piv txwv ntawm cov txheej txheem isentropic. Ntxiv mus, qhov tsis tu ncua ntawm cov txheej txheem isentropic yog entropy, equilibrium, thiab tshav kub zog.
Cov txheej txheem no yog cov txheej txheem thermodynamic zoo tshaj plaws uas yog adiabatic, tab sis cov cua sov hloov pauv tsis muaj kev sib txhuam, uas txhais tau tias tsis muaj kev hloov ntawm cov cua sov lossis teeb meem, thiab cov txheej txheem rov qab los.
Qhov txawv ntawm Adiabatic thiab Reversible Adiabatic Process yog dab tsi?
Cov txheej txheem adiabatic tuaj yeem txhais tau tias yog kev hloov pauv ntawm qhov system uas tsis muaj cua sov hloov mus rau hauv lossis tawm ntawm lub cev. Cov txheej txheem thim rov qab adiabatic tseem hu ua cov txheej txheem isentropic. Qhov sib txawv tseem ceeb ntawm cov txheej txheem adiabatic thiab thim rov qab adiabatic yog tias nyob rau hauv cov txheej txheem adiabatic, cov txheej txheem adiabatic yog rwb thaiv tsev thiab tsis tso cai rau kev hloov pauv cua sov, thaum cov txheej txheem thim rov qab adiabatic cuam tshuam nrog kev hloov pauv cua sov uas qhov ntau ntawm cov cua sov hloov mus ncaj qha rau qhov hloov pauv hloov pauv. ntawm qhov system.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm cov txheej txheem adiabatic thiab thim rov qab cov txheej txheem adiabatic hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Adiabatic vs Reversible Adiabatic Process
Adiabatic cov txheej txheem yog cov txheej txheem thermodynamic uas tsis muaj qhov hloov hluav taws xob tshwm sim vim yog cov tshuaj tiv thaiv. Qhov sib txawv tseem ceeb ntawm cov txheej txheem adiabatic thiab thim rov qab adiabatic yog tias nyob rau hauv cov txheej txheem adiabatic, cov txheej txheem adiabatic yog rwb thaiv tsev thiab tsis tso cai rau kev hloov pauv cua sov, thaum cov txheej txheem thim rov qab adiabatic cuam tshuam nrog kev hloov hluav taws xob uas qhov ntau ntawm cov cua sov hloov mus ncaj qha rau qhov hloov pauv ntawm entropy. lub system.
