Kev nce qhov loj me ntawm cov kuab tshuaj yuav tsis cuam tshuam rau tus nqi ntawm kev so, vim hais tias kom cov kuab tshuaj yaj sai dua tus naj npawb ntawm kev sib tsoo ntawm cov kuab tshuaj thiab cov kuab tshuaj yuav tsum tau ua. nce, qhov loj ntawm cov khoom tsis muaj teeb meem.
Yuav ua li cas tsis nce tus nqi tawg?
1 Cov Lus TebKev sib xyaw ua ke coj cov khib nyiab tshiab hauv kev sib cuag nrog cov kuab tshuaj tshiab uas ua kom nrawm nrawm. Txo qhov kub thiab txias txo cov kinetic zog ntawm cov molecules uas slows dissolving. Ua kom qhov chaw saum npoo ntawm cov khoom ua rau ntau qhov chaw hu rau cov kua uas ua kom nrawm nrawm.
Qhov twg hauv qab no yuav tsis nce tus nqi uas tus solute dissolves cua sov cov kuab tshuaj crushing lub solute txias cov kuab tshuaj stirring?
Kev piav qhia: Cooling cov kuab tshuaj yuav tsis nce tus nqi ntawm cov kuab tshuaj yaj vim tias thaum peb txias cov kuab tshuaj ces qhov kev txav ntawm cov khoom txo qis. Yog li ntawd, yuav muaj kev cuam tshuam tsawg dua ntawm cov kuab tshuaj thiab cov kuab tshuaj raws li qhov tshwm sim ntawm qhov kev sib cais txo qis.
Yuav ua li cas nce tus nqi uas tus solute dissolves?
kub . Heating nce cov kuab tshuaj muab cov molecules ntau lub zog kinetic. Qhov kev txav nrawm dua txhais tau tias cov kuab tshuaj molecules sib tsoo nrog cov kuab tshuaj nrog ntau zaus thiab kev sib tsoo tshwm sim nrogntau zog. Ob qho xwm txheej nce tus nqi ntawm qhov solute dissolves.
Yuav ua rau nce tus nqi ntawm kev solute?
stlring . stirring a solute into a solvent speeds up the rate of dissolvev because it help distribute the solute particles thoob plaws hauv cov kuab tshuaj. Piv txwv li, thaum koj ntxiv qab zib rau cov tshuaj yej iced thiab ces do cov tshuaj yej, cov suab thaj yuav yaj sai dua.
