Ubala njani iqondo lobushushu bomphunga?

Iqondo lobushushu bomphunga (elikwabizwa ngokuba yindawo yokubilisa) yento ingabalwa kusetyenziswa iindlela ezahlukeneyo, ngokuxhomekeke kwidatha ekhoyo kunye neempawu ezithile zento. Nazi iindlela ezimbalwa eziqhelekileyo zokubala iqondo lobushushu bomphunga:

1. Sebenzisa idatha yeekhemikhali: Iqondo lobushushu lobushushu bento bunokufumaneka ngokwesiqhelo kwiinkcukacha zeekhemikhali okanye kuncwadi. Izinto ezininzi zineendawo zokubilisa ezibhalwe kakuhle kuxinzelelo oluqhelekileyo (1atmosphere). Le yeyona ndlela ilula kwaye ichaneke kakhulu yokumisela ubushushu bokuguquka kwamanzi ukuba idata ikhona.

2. Sebenzisa i-equation yeClausius-Clapeyron: I-equation yeClausius-Clapeyron ingasetyenziselwa ukuqikelela utshintsho kuxinzelelo lomphunga wento njengomsebenzi wobushushu. Ngokucwangcisa i-logarithm yendalo yoxinzelelo lomphunga ngokuchasene ne-reciprocal yeqondo lokushisa, i-slope yomgca obangelwayo ingasetyenziselwa ukubala i-enthalpy ye-vaporization, enokuthi isetyenziswe ukuqikelela indawo yokubilisa kwiingcinezelo ezahlukeneyo.

3. Sebenzisa idatha yoxinzelelo lomphunga: Ukuba idatha yoxinzelelo lomphunga yento kumaqondo obushushu ahlukeneyo iyafumaneka, ungasebenzisa i-equation ka-Antoine okanye enye iempirical equation ukuze ilingane idatha kwaye uchaze indawo yokubilisa kuxinzelelo oluqhelekileyo.

4. Sebenzisa i-molecular dynamics simulations: Kwizinto eziyinkimbinkimbi okanye xa idatha yovavanyo ilinganiselwe, ukulinganisa ukuguqulwa kwee-molecular dynamics kunokusetyenziswa ukubala ukushisa kwe-evaporation ngokusekelwe kwindlela yokuziphatha kwee-molecule kunye nokusebenzisana kwazo.

Kubalulekile ukuba uqaphele ukuba ukuchaneka kweqondo lokushisa elibalwayo lokunyuka lixhomekeke kumgangatho wedatha kunye nendlela esetyenzisiweyo. Xa uphethe izinto eziyingozi, kubalulekile ukujonga imithombo ethembekileyo kwaye uqinisekise ukuba amanyathelo okhuseleko ayalandelwa.

Zeziphi iimeko ezi-3 ezilungele ukuphuphuma kwamanzi?

Ezona meko zintathu zifaneleke kakhulu ukuba ngumphunga zezi:

1. Ubushushu obuphezulu: Ubushushu buvela ngokukhawuleza kumaqondo obushushu aphezulu kuba ukonyuka kwamandla obushushu kunika iimolekyuli amandla amakhulu ekinetic, okubavumela ukuba boyise amandla e-intermolecular kwaye babaleke kwisigaba solwelo ukuya kwisigaba segesi.

2. Ukufuma okuphantsi: Ukufuma komoya okwindawo engqongileyo kuphantsi kwaye umahluko woxinzelelo lomphunga phakathi kolwelo nomoya mkhulu, nto leyo enceda ukuphuphuma komphunga ngokukhawuleza. Xa umoya ugcwele umphunga wamanzi (ukufuma okuphezulu), izinga lokunyuka komphunga liyehla ngenxa yokuba i-concentration gradient yeemolekyuli zamanzi ezihamba ukusuka kwisigaba solwelo ukuya kwisigaba segesi siyancipha.

3. Indawo eyongeziweyo yomphezulu: Indawo enkulu yolwelo evezwe kumoya ojikelezileyo ikhuthaza ukuvela komphunga ngokukhawuleza. Yiyo loo nto, umzekelo, iimpahla ezimanzi zome ngokukhawuleza xa zisasazwa kunokuba zidibanise, kuba indawo eyongeziweyo yendawo ivumela iimolekyuli ezininzi zamanzi ukuba zibaleke emoyeni.

Ngokudibeneyo, ezi meko zinceda ukunyusa izinga lokuphuma komphunga, zivumela izinto ukuba zitshintshe ukusuka kulwelo ukuya kwisigaba segesi ngokufanelekileyo.
