Karolelano ea matla a kinetic a khase

Ntle le kgatello, e 'ngoe ea bongata bo bontšang thepa ea macroscopic ea khase ke mocheso (T). Tekanyo ea khatello ea khase e nkiloeng sehloohong sa Khopolo-taba ea Kinetic ea Khase e ngotsoe hape:

Tekanyo ea Molao oa Khase o Loketseng e nkiloeng sehloohong sa Molao oa Khase o Loketseng e ngotsoe hape:

PV = NkT → Tekanyo b

Nahana ka equation a le equation b. Mahlakore a letsohong le letshehadi a lekana, ha mahlakore a letsohong le letona a batla a lekana. Kaha mahlakore a letsohong le letshehadi a lekana, diequation tsena tse pedi di ka kopanngwa:

Haeba re atisa mahlakore a letshehadi le a le letona ka 3/2, equation ena e tla fetola sebopeho sa yona ho:

Thempereichara e lekana ka ho toba le matla a tloaelehileng a kinetic a phetolelo ea limolek'hule tsa khase. Ha mocheso o phahame, matla a tloaelehileng a kinetic a phetolelo a ba maholo, ka lehlakoreng le leng, ha mocheso o le tlase, matla a tloaelehileng a kinetic a phetolelo a ba manyane. Re ka etsa qeto ea hore mocheso ke tekanyo ea matla a tloaelehileng a kinetic a phetolelo ea limolek'hule.

Tekanyo ea mocheso o felletseng khahlanong le matla a kinetic a phetolelo ea 2 e ka ngoloa ka mokhoa o fapaneng:

Pele, Matla a kinetic a phetolelo ke matla a kinetic a nang le ntho kapa molek'hule e fetang motsamaong oa phetolelo. Motsamao oa phetolelo e ka ba o otlolohileng, o oblique, kapa oa parabolic. Matla a eona a tšoanang le ona ke matla a kinetic a potolohang. Matla a kinetic a potolohang ke matla a kinetic a nang le ntho kapa molek'hule e fetang motsamaong oa potoloho.

Ea bobeli, Matla a tloaelehileng a kinetic a phetolelo ho equation e kaholimo a sebetsa feela ho likhase tsa monatomiki. Mehlala ea likhase tsa monatomiki ke He (helium), Ar (argon), jj. Ntle le likhase tsa monatomiki, ho boetse ho na le likhase tsa diatomiki. Mohlala oa khase ea diatomiki ke O₂ (oksijene), N₂ (naetrojene), CO (carbon monoxide), jj. Hape ho na le dikhase tsa polyatomic. Mohlala, CO₂ (carbon dioxide) jj. Dikhase tsa Monatomic di bopilwe ka athomo e le nngwe feela, dikhase tsa diatomo di bopilwe ka diathomo tse pedi mme dikhase tsa polyatomic di bopilwe ka diathomo tse ngata.

Ea boraro, mocheso o felletseng o lokela ho hlahiswa ka sekala sa Klevin (K). Haeba mocheso o ntse o le ka sekala sa Celsius (^oC), e fetole pele ho ea sekaleng sa Kelvin (K).

Ea bone, Tekanyo ea 1 le equation ea 2 tse ka holimo ha li sebetse feela likhaseng, empa li boetse li sebetsa le linthong tse metsi le likhaseng.

Mohlala oa mathata:

Karolelano ea matla a kinetic a phetolelo ea limolek'hule tse ka har'a khase e 40°C ke efe? ^oC?
