Kodi Gibbs ufulu mphamvu?

Free Gibbs mphamvu - ndi kufunika kosonyeza mlingo wa kusintha mphamvu mu mankhwala anachita, ndi chifukwa cha kupereka yankho ku funso zokhuza kuthekera zosiyanasiyana mankhwala. kuthekera Izi angathe kumwedwa kwa mankhwala mphamvu dongosolo zonse (madzi galasi, ndi zina zotero. D.). Gibbs ufulu mphamvu chimagwiritsidwa ntchito umagwirira ndi yopezeka m'zinthu zachilengedwe.

The ndimve kulankhula kwa njira isobaric-isothermal anatsimikiza ndi zinthu zotsatirazi: enthalpy ndi mphamvu zosagwiritsika ntchito. Woyamba amagwirizana ndi kuchepa enthalpy a dongosolo lino, pamene lachiwiri zotere mlingo chifukwa kuwonjezeka mu dongosolo chifukwa kuchuluka kwa mphamvu zosagwiritsika ntchito zake. kusiyana anafotokoza thermodynamic chinthu ndi ntchito kwa dongosolo States, chikudziwika ngati isobaric-isothermal osiyanasiyana, kapena Gibbs ufulu mphamvu (G, KJ).

Mowiriza ndondomeko m'dongosolo womasuka ndi chatsekedwa anafotokozedwa ndi muyezo yeniyeni, ikutchedwa ndi Gibbs angathe. Ndipotu ndi boma ntchito. D. U. Gibbs, pamene ntchito ndi kachitidwe thermodynamic, anabweretsa mbali mwa enthalpy ndi mphamvu zosagwiritsika ntchito. Gibbs ufulu mphamvu amalola kulosera za akulowera njira mowiriza zamoyo ndi kuonanso Mwachangu ake theoretically zothekadi.

Pankhani wachiwiri malamulo yopezeka m'zinthu zachilengedwe Gibbs mfundo akhoza mwachidule motere: pa sanasiye kutiuza ndi kutentha popanda chikoka kuchokera kunja dongosolo amakhala mlingo wa ndimve kulankhula kokha kwa njira zimene zikuchitika chifukwa kuchepa mtengo wa Gibbs lingathe mlingo umene umachitika akafike iwo azilandira osachepera. Choncho, ndi bwino thermodynamic dongosolo Mzimuyo wosasinthika ufulu mphamvu. Choncho, kuthekera kwa Gibbs 'ufulu enthalpy ndi mu dongosolo isobaric-isothermal. Tiyeni tione chifukwa chake anasonyeza osachepera. Zimenezi zalongosoledwa ndi zopanda zofunika yopezeka m'zinthu zachilengedwe mgwirizano, motere: a boma anapatsidwa chikhalidwe cha kutentha zonse ndi kuthamanga zikutanthauza kuti kusintha zotsatirazi zofunika kuwonjezera mlingo mphamvu, ndipo izi zimatheka ndi kusintha zinthu zina.

Ndipo tanthauzo la ufulu mphamvu? Ndi mawu amenewa amatanthauza njira yodalirika ndalama malire mphamvu popanda kapena ndi ndalama zazing'ono mphamvu. Ndiko kuti, mphamvu kuwapeza dzuwa, opangira magetsi, chopangira mphamvu mphepo - ndi mphamvu free, chifukwa ife sitikufuna kuwononga mphamvu kuti dzuŵa nagwa pansi, madzi zimapita ku mtsinje kapena mphepo idawomba. M'zinthu zimenezi otizungulira pali ambiri, ambiri a iwo omwe sakudziwika kwa sayansi. Umene uli pa iwo nthawi ndi 'kutipunthwitsa' woyamba Zikusiyana experimenters. Imodzi mwa ntchito zaluso zimenezi inali mphamvu ufulu wa Tesla. Malinga ndi asayansi, mphamvu adalandira, anatenga kunayambira ku efa (zingalowe). Ndi chisoni kuti chidali chifuniro chake sunapite kutha zomveka. Komabe, zinthu ngati zimenezi kukhala odzipereka, ndondomeko silitiletsa. Masiku ano, pali zambiri eni luso, chifukwa cha zimene - ufulu mphamvu. Dera la munthu zipangizo zimenezi, pamwamba.
