Cov taw tes ntawm uas cov dej saturated thiab saturated chav kab sib ntsib yog lub npe hu ua qhov tseem ceeb . Raws li lub siab nce mus rau lub qhov tseem ceeb lub enthalpy ntawm evaporation txo, kom txog rau thaum nws ua xoom ntawm lub qhov tseem ceeb.

Yog li ntawd, yuav ua li cas tshwm sim ntawm qhov tseem ceeb?

Hauv thermodynamics, a qhov tseem ceeb (los yog tseem ceeb xeev) yog qhov kawg taw tes ntawm ib theem equilibrium nkhaus. Cov piv txwv tseem ceeb tshaj plaws yog cov kua-vapor qhov tseem ceeb , qhov kawg taw tes ntawm lub siab-kub nkhaus uas xaiv cov xwm txheej raws li cov kua thiab nws cov vapor tuaj yeem ua ke.

Ib yam li ntawd, qhov txawv ntawm qhov tseem ceeb thiab triple point yog dab tsi? A qhov tseem ceeb (los yog tseem ceeb xeev) yog qhov kawg taw tes ntawm ib theem equilibrium. Triple point ntawm ib yam khoom yog qhov kub thiab siab uas peb theem (gas, kua, thiab khoom) ntawm cov khoom ntawd coexist nyob rau hauv thermodynamic equilibrium.

Kuj Paub, qhov kub tseem ceeb ntawm chav yog dab tsi?

Chav Generators Lub ntsiab lus ntawm qhov qhov kub thiab txias thiab tseem ceeb siab tau ntsib yog hu ua tseem ceeb taw tes. Cov tseem ceeb siab thiab qhov kub thiab txias ntawm dej thiab chav 22.12 MPa thiab 647.14 K, feem.

Vim li cas lub ntsiab lus tseem ceeb?

Qhov tseeb no feem ntau pab txheeb xyuas qhov sib txuas lossis hauv kev daws teeb meem. Cov qhov tseem ceeb yog qhov kub thiab siab tshaj plaws uas cov khoom siv ntshiab tuaj yeem muaj nyob hauv vapor/kua sib npaug. Thaum kub siab tshaj qhov tseem ceeb qhov kub thiab txias, cov khoom tsis tuaj yeem nyob ua kua, txawm tias lub siab npaum li cas.
