Vapor

Mo lefapheng la fisikisi, mouwane (American English) kgotsa mouwane (British English le Canadian English; bona dipharologano tsa mopeleto) ke selo se se mo seemong sa gase mo thempereitšhareng e e kwa tlase ga thempereitšhara ya sone e e masisi, se se rayang gore mouwane o ka tswakanyediwa go nna seedi ka go oketsa kgatelelo mo go ona ntle le go fokotsa thempereitšhara ya mouwane. Mowa o farologana le aerosol. Aerosol ke go tlhatlhamololwa ga dikarolwana tse dinnye tsa seedi, tse di tiileng, kgotsa ka bobedi mo teng ga gase.

Sekai, metsi a na le themperetšha e e masisi ya 647 K (374 °C; 705 °F), e e leng themperetšha e e kwa godimo e metsi a a metsi a ka nnang teng ka kgatelelo nngwe le nngwe. Mo atemosefereng ya maemo a a tlwaelegileng a themperetšha, metsi a gase (a a bidiwang mouwane wa metsi) a tla nna seedi fa kgatelelo ya one e oketsega ka tsela e e lekaneng.

Mouwane o ka nna teng mmogo le seedi (kgotsa selo se se tiileng). Fa seno se le boammaaruri, dikgato tse pedi di tla bo di le mo tekatekanong, mme kgatelelo ya gase e e rileng e tla lekana le kgatelelo ya mouwane wa tekatekanyo ya seedi (kgotsa se se tiileng).

Ntlha e e masisi ya mouwane-seeledi mo thulaganyong ya kgatelelo-themperetšha ya kgato e mo thempereitšhareng e e kwa godimo ya molelwane wa kgato ya seeledi-gase (mogala o motala o o nang le marontho o bontsha boitshwaro jo bo sa tlwaelegang jwa metsi).

Mowa o raya fa e le gase e e mo thempereitšhareng e mo go yone selo se se tshwanang se ka nnang teng gape se le seedi kgotsa se le thata, ka fa tlase ga thempereitšhara e e masisi ya selo seo. (Ka sekai, metsi a na le themperetšha e e kwa godimo ya 374 °C (647 K), e leng themperetšha e e kwa godimo thata e metsi a ka nnang teng fa a le mo seemong sa go nna seedi.) Fa mowa o kopana le seedi kgotsa seedi se se thata, dikarolo tseno tse pedi di tla bo di lekalekane. Lereo "gase" le kaya seedi se se kgonang go gatelelwa. Gase e e sa fetogeng ke gase e e sa kgoneng go nna le seedi kgotsa selo se se tiileng mo themperetšhareng ya gase, jaaka mowa mo dithemphoritšhareng tse di tlwaelegileng. Seedi kana selo se se tiileng ga se tlhoke go bela gore se ntshe mowa.

Mouwane ke one o dirang gore go nne le maru le go koelana ga one. Gantsi e dirisetswa go dira dithulaganyo tsa go tlhotlhwa ga disele le go ntshiwa ga metsi mo sampoleng ya seedi pele ga go dirwa chromatography ya gase.

Dimolekhule tse di bopang mouwane di na le metsamao ya go roroma, go dikologa le go tsamaya. Ditshukudu tseno di tsewa tsia mo thutong ya dikhase.

kgatelelo ya mouwane

The vapor pressure is the equilibrium pressure from a liquid or a solid at a specific temperature. The equilibrium vapor pressure of a liquid or solid is not affected by the amount of contact with the liquid or solid interface.

metsi– equilibrium

The normal boiling point of a liquid is the temperature at which the vapor pressure is equal to normal atmospheric pressure.

Fa kgatelelo ya mouwane e feta boleng jwa tekatekano, e nna e e tletseng thata mme e bo e tsidifala mo mafelong ape fela a a leng teng a go ka nnang ga nna le nuklea, jaaka dikarolwana tsa lerole. Molaomotheo ono o dirisiwa mo diphaposing tsa maru, koo go bonwang dikarolwana tsa marang gone ka gonne di dira gore go nne le marothodi a metsi.

For two-phase systems (e.g., two liquid phases), the vapor pressure of the individual phases are equal. In the absence of stronger inter-species attractions between like-like or like-unlike molecules, the vapor pressure follows Raoult's law, which states that the partial pressure of each component is the product of the vapor pressure of the pure component and its mole fraction in the mixture. The total vapor pressure is the sum of the component partial pressures.

Go lekanya mouwane

E re ka se le mo kgatong ya gase, selekanyo sa mouwane se lekanyediwa ka kgatelelo ya gase. Mo godimo ga moo, mouwane o latela thulaganyo ya barometric mo lebaleng la maatlakgogedi, fela jaaka digase tse di tlwaelegileng tsa atemosefere di dira.
