Thermodynamics yog ib ceg ntawm physics uas kawm txog thermal zog thiab cov hauv paus ntsiab lus ntawm nws kev faib thoob plaws hauv lub ntim ntawm ib yam khoom los yog ib qho nruab nrab. Qhov kev qhuab qhia no yog ua raws li qee qhov kev cai thoob ntiaj teb thiab siv cov kev paub ntawm ntau lwm yam kev tshawb fawb. Thermodynamic equilibrium yog lub hauv paus ntawm cheeb tsam ntawm kev paub txog kev paub.
Ib qho tseem ceeb tshaj plaws thiab tej zaum qhov tshwj xeeb tshaj plaws ntawm cov khoom muaj sia nyob yog lawv lub peev xwm tshwj xeeb los hloov lub zog thiab khaws cia rau hauv ntau hom. Thermodynamic equilibrium yog xws li lub xeev ntawm ib tug system nyob rau hauv uas nws tsis thiab cov yam ntxwv tsis tuaj yeem hloov lub sij hawm tsis muaj kev cuam tshuam ntawm lwm yam.
Ntawd yog: lub cev lub cev sib cais raws li kev xav, suav nrog ib lossis ntau yam khoom siv lub cev, tuaj yeem nyob hauv lub xeev ntawm kev tshuav nyiaj li cas. Yog hais tias qhov sib npaug ntawm qhov sib npaug ntawm cov thermodynamic raug cuam tshuam, txhua qhov system yuav zoo li rov qab losrau nws lub xeev ruaj khov ntawm nws tus kheej. Qhov no yog ib qho ntawm cov hauv paus ntsiab lus ntawm physics, uas ntau dhau yog tsim nyob rau hauv peb lub neej thiab nyob rau hauv xwm.
Txoj hauv kev yooj yim tshaj plaws los xav txog qhov sib npaug ntawm qhov ntsuas kub yog los ntawm qhov piv txwv ntawm tib neeg tus yam ntxwv zoo li lub thermos nrog cov tshuaj yej kub, uas yog qhov sib cais heev. Tau kawg, qhov kub ntawm txhua qhov chaw ntawm cov khoom (qhov no, tshuaj yej) yuav zoo ib yam. Tab sis yog tias koj tso lub thawv dej khov rau hauv lub thermos, qhov sib npaug ntawm qhov ntsuas kub yuav raug cuam tshuam tam sim ntawd, vim tias yuav muaj qhov sib txawv ntawm qhov sib txawv ntawm cov kua.
Nyob rau hauv rooj plaub no, kev hloov hluav taws xob yuav tshwm sim los ntawm thaj tsam ntawm qhov kub siab dua mus rau qhov chaw txias dua, kom txog rau thaum qhov sib xws ntawm thermal tswj tau tsim thoob plaws hauv lub ntim. Thaum qhov no tshwm sim, stability yuav rov qab los. Qhov no yog li cas cov txheej txheem thermodynamic ua haujlwm, tsis hais nws qhov ntsuas thiab pes tsawg ntawm cov khoom nws muaj.
Qhov tseem ceeb ntawm kev sib npaug, uas yog qhov ntsuas kub ib yam ntawm txhua lub ntsiab lus hauv lub cev, tshwj xeeb tshaj yog rau cov kab mob nyob. Txhua yam khoom siv roj ntsha xav tau lub zog tsis tu ncua los tswj lub neej ib txwm muaj. Tag nrho cov txheej txheem lom neeg kuj xav tau kev hloov pauv kub ruaj khov thiab kev faib khoom sib xws.
Piv txwv li, cov nroj tsuag, khaws cov hnub ci zog, hloov nws mus rau hauv cov tshuaj sib txuas ntawm cov organic tshuaj los ntawmphotosynthesis. Nyob rau hauv lub cev ntawm cov tsiaj, txhua yam tshwm sim raws nraim qhov opposite - organic tshuaj tau txais nrog zaub mov yog hloov dua siab tshiab rau hauv lub zog. Tag nrho cov txheej txheem zoo li no (rau cov neeg sawv cev ntawm cov nroj tsuag thiab tsiaj ntiaj teb) tshwm sim nyob rau hauv nruj raws li cov hauv paus ntsiab lus ntawm lub thermodynamic system.
Lub ntsiab lus tseem ceeb ntawm thermodynamics yog universal thiab unshakable rau ob qho tib si nyob rau hauv biological systems thiab inanimate xwm. Lub hauv paus ntsiab lus ntawm thermodynamics hais tias ib qho kev sib sau ntawm cov khoom muaj feem xyuam tuaj yeem hu ua thermodynamic system. Qhov sib txawv tsuas yog nyob rau hauv cov nplai thiab cov khoom siv. Piv txwv ntawm cov kab ke no yog cov hlwb ntawm peb lub cev, lub plawv lossis lwm yam hauv nruab nrog cev. Tag nrho cov kab mob kuj tseem nyob rau hauv qee qhov kev txiav txim siab ib qho thermodynamic system. Txawm tias tej yam khoom loj xws li biosphere, cov dej hiav txwv kuj muaj nyob rau hauv pawg no. Thiab lawv raug rau tib txoj cai ntawm qhov sib npaug ntawm qhov ntsuas kub.
