Piv txwv ntawm colligative zog muaj xws li vapor siab txo qis, khov point kev nyuaj siab , osmotic siab, thiab boiling point elevation.
Tsis tas li lo lus nug yog, plaub hom kev sib koom ua ke yog dab tsi?
Plaub feem ntau kawm colligative zog yog freezing point kev nyuaj siab , kub point qhov siab, vapor siab txo, thiab osmotic siab . Txij li thaum cov khoom no tau txais cov ntaub ntawv ntawm tus naj npawb ntawm cov ntsiab lus hauv cov tshuaj, ib tus tuaj yeem siv lawv kom tau txais qhov hnyav molecular ntawm cov kua.
Ib tug kuj yuav nug, dab tsi Colligative khoom yog lub luag hauj lwm rau antifreeze? Antifreeze ua haujlwm vim tias cov dej khov thiab kub kub ntawm cov kua yog "colligative" khoom. Qhov no txhais tau tias lawv nyob ntawm qhov concentrations ntawm " soluble ,”los yog yaj tshuaj, nyob rau hauv lub daws . Ib tug ntshiab daws khov vim qhov kub qis ua rau cov molecules qeeb.
Tsis tas li ntawd, Colligative Properties yog dab tsi?
Colligative zog ntawm kev daws teeb meem yog khoom uas nyob ntawm qhov concentration ntawm cov kuab tshuaj molecules los yog ions, tab sis tsis raws li tus kheej ntawm cov kua. Colligative zog muaj xws li vapor siab txo qis, boiling point elevation, freezing point depression, thiab osmotic siab.
Qhov twg tsis yog Colligative Properties?
Lwm qhov tsis yog- colligative khoom yog xim ntawm kev daws. 0.5 M daws ntawm CuSO4 yog ci xiav nyob rau hauv sib piv rau cov xim tsis muaj ntsev thiab qab zib tov. Lwm yam uas tsis yog- colligative zog suav nrog viscosity, nto nro, thiab solubility.

Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Cov piv txwv ntawm tsev neeg cov kua qaub thiab cov hauv paus yog dab tsi?
Daim ntawv teev cov tsev Bases & Acids Baking Soda. Baking soda yog lub npe nrov rau sodium bicarbonate, paub tshuaj raws li NaHCO3. Diluted Soaps. Tsev neeg Ammonia. Tsev Neeg Vinegar. Citric Acid
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
