Vim tias lub zog kinetic ntawm ib lub molecule yog proportional rau nws qhov kub thiab txias, evaporation nce ntxiv nrawm dua ntawm qhov kub siab dua Raws li cov molecules nrawm dua khiav tawm, cov molecules seem muaj qis dua nruab nrab kinetic. lub zog, thiab qhov kub ntawm cov kua txo qis.
evaporation kub yog dab tsi?
Evaporation yog txheej txheem uas cov dej hloov ntawm cov kua mus rau cov pa los yog vapor. Dej boils ntawm 212 degrees F (100 degrees C), tab sis nws yeej pib evaporate ntawm 32 degrees F (0 degrees C); nws tsuas yog tshwm sim qeeb heev. Raws li qhov kub thiab txias nce, tus nqi ntawm evaporation kuj nce.
Puas kub nce hauv evaporation?
Txawm hais tias cov dej tuaj yeem evaporate ntawm qhov kub thiab txias, tus nqi ntawm evaporation nce raws li qhov kub thiab txias nceQhov no ua rau kev txiav txim siab vim tias nyob rau qhov kub siab dua, ntau cov molecules txav nrawm dua; yog li ntawd, nws muaj feem ntau dua rau cov molecule kom muaj lub zog txaus kom tawg tawm ntawm cov kua los ua roj.
Vim li cas kub nce evaporation?
evaporation tus nqi siab dua ntawm qhov kub siab dua vim raws li qhov kub nce, lub zog tsim nyog rau evaporation txo qis… Cua txav hla dej lossis av tuaj yeem nqa cov pa tawm mus., qhov tseem ceeb ziab huab cua, uas ua rau kom nce evaporation tus nqi.
Yuav ua li cas rau qhov kub thiab txias thaum lub sij hawm evaporation?
Evaporation yog hom vaporization ntawm cov kua uas tsuas yog tshwm sim ntawm cov kua dej. … Raws li cov molecules khiav nrawm dua, cov molecules uas tseem tshuav muaj lub zog nruab nrab qis qis, thiab qhov kub ntawm cov kua txo qis Qhov tshwm sim no tseem hu ua evaporative txias.
