A canji a entropy

Tabarbarewa shi ne ra'ayi cewa da aka gabatar a thermodynamic. Amfani da wannan darajar aka ƙaddara da makamashi watsawa gwargwado. Duk wani tsarin da aka fuskantar da adawa da ya auku tsakanin zãfi, da karfi filin. A karuwa a yawan zafin jiki take kaiwa zuwa rage a cikin mataki na ordering. Don ƙaddara su ƙaddarawa na rikice da kuma gabatar da yawa kira entropy. Yana characterizes musayar makamashi gudana biyu a rufaffiyar da kuma bude tsarin.

A entropy canji a ware haihuwarka auku a cikin shugabanci na kara tare da ci gaban da zafi. Kara da darajar, wannan awo da cuta kai a jihar halin da thermodynamic ma'auni, wanda yake shi ne mafi m.

Idan tsarin ne bude da kuma a lokaci guda ba ma'auni, da entropy canji ne ga downside. The girma na wannan ma'auni a cikin wannan embodiment ne halin da siffantawa. Domin samun summation na biyu dabi'u:
- entropy juyi abin da ke faruwa saboda zafin rana da kuma musayar abubuwa daga waje yanayi.
- da adadin canji nuna alama m motsi a cikin tsarin.

entropy canji yakan faru a cikin wani yanayi inda kwarara nazarin halittu, da kuma sinadaran jiki matakai. Wannan sabon abu ne ya gane a wani gudun. A entropy canji iya zama wani tabbatacce darajar - a cikin wannan harka akwai da inflow na nuna alama ga tsarin daga waje muhalli. Akwai iya zama lokuta a lokacin da darajar nuna canji a entropy aka bayyana tare da wani "debe". Wannan na lamba darajar nuna outflow entropy. A tsarin na iya zama a wani kwari jihar. A irin wannan hali da adadin samar aka cika ta da wani outflow entropy index. Wani misali na wannan halin da ake ciki ne a jihar da wani rai gabar. Yana da wani unbalanced, amma a lokaci guda har abada. Duk wani kwayoyin tana entropy da ciwon wani mummunan darajar ta muhalli. Kadaici cuta matakai daga gare iya ko wuce darajar samu.

Tabarbarewa samarwa na faruwa a wani hadadden tsarin. A lokacin juyin halitta, bayanai da aka yi musayar tsakanin su. Alal misali, a lokacin da ruwa evaporates, rasa bayanai a kan sarari tsari na ta kwayoyin. Akwai wani tsari na kara tabarbarewa. Idan ruwa ne daskarewa, da wuri da rashin tabbas rage-rage kwayoyin. A wannan yanayin, da entropy rage-rage. Sanyaya na cikin ruwa yana sa a rage na ciki makamashi. Duk da haka, a lokacin da zafin jiki da kai wani daraja, duk da kau da zafi daga ruwa zazzabi daga cikin kayan zauna canzawa. Wannan yana nufin cewa gwamnatin rikon kwarya farawa zuwa crystallize. A entropy canji a wani isothermal aiwatar da irin wannan ne tare da wani karu a randomness index matakan tsarin.

A m Hanyar to auna zafin jiki da kuma zafi na fe daga wani abu, yana rike da aikin, da sakamakon wanda - gina solidification zane. A wasu kalmomin, bisa bayanai samu daga nazarin iya zana kwana wanda yake nuna dogaro da yawan zafin jiki na kasa a kan lokaci. A waje yanayi dole ne guda. Ƙayyade da canji a entropy ne zai yiwu ta data sarrafa hoto sakamakon gwajin. A irin wannan masu lankwasa ne ko da yaushe a yankin a wadda a kwance line tazara. A zafin jiki m ga wannan sashi, shi ne yawan zafin jiki na solidification.

Canza wani abu tare da miƙa mulki daga m zuwa wani ruwa a cikin zafin jiki na ta yanayi, daidai da narkewa zafin jiki, da kuma mataimakin versa, sun hada da wani lokaci canji na farko irin. Wannan ya canza da yawa daga cikin tsarin, ta ciki makamashi da kuma entropy.
