Kev sib txhuam yog ib zog tshwm sim los ntawm ob yam uas rub ua ke. Cua tsis kam thiab dej tsis kam yog hom kev sib txhuam. Lawv hu ua tsis yog - tiv tauj rog.
Yog li ntawd, yog cov tshuaj tiv thaiv tsis sib cuag?
Nyob rau hauv sib piv a tiv tauj zog yog a zog siv rau lub cev los ntawm lwm lub cev uas nyob hauv tiv tauj nrog nws. Tag nrho plaub qhov kev paub txog kev sib cuam tshuam yog tsis yog - tiv tauj rog : Lub zog nuclear zog mediates ob qho tib si nuclear fission thiab fusion cov tshuaj tiv thaiv.
Qhov thib ob, dab tsi yog qhov tsis sib cuag quab yuam Chav Kawm 8? Tsis yog - tiv tauj rog : Kev quab yuam uas tshwm sim tsis muaj tiv tauj ntawm 2 lossis ntau dua cov khoom koom nrog. Piv txwv li: Sib nqus quab yuam , Electrostatic quab yuam , Gravitational zog . Sib nqus quab yuam yog a zog uas attracts tej yam khoom hlau (xws li hlau thiab hlau filings) mus rau ib tug hlau nplaum.
Yog li ntawd, dab tsi yog cov piv txwv ntawm cov tsis sib cuag rog?
Piv txwv ntawm Cov Tub Rog Tsis Tiv Thaiv yog:
- Gravitational quab yuam.
- Sib nqus quab yuam.
- Electrostatics.
- Nuclear quab yuam.
Puas yog electrostatic quab yuam tsis sib cuag?
Electrostatic zog yog tsis yog - tiv tauj rog ; lawv rub lossis thawb rau ntawm cov khoom yam tsis tau kov lawv. Kev rub qee cov ntaub ntawv ua ke tuaj yeem ua rau qee yam hu ua 'them' raug txav ntawm ib qho chaw mus rau lwm qhov. Cov khoom uas raug them rub rau lwm yam khoom uas tsis tau them thiab tej zaum yuav thawb lossis rub rau lwm yam khoom uas raug them.

Puas yog HClO muaj zog lossis tsis muaj zog?
HClO yog ib qho kua qaub raws li nws muaj cov proton uas nws tso tawm tab sis nws yog ib qho tsis muaj zog acid vim nws tsis yog ib qho acidamoung cov npe ntawm cov kua qaub muaj zog
Lub cev puas tuaj yeem muaj lub zog tsis muaj zog muab qhov laj thawj?
Teb thiab piav qhia: Lub cev tsis tuaj yeem muaj lub zog tsis muaj zog. Qhov no yog vim hais tias tsuas yog txav cov khoom havemomentum, thiab ib yam khoom nyob rau hauv motion ib txwm haskinetic
Puas muaj zog acid thiab qaug zog hauv paus ua rau tsis muaj?
Raws li koj tau pom hauv kev suav cov pH ntawm cov kev daws teeb meem, tsuas yog ib qho me me ntawm cov kua qaub uas muaj zog heev yog qhov tsim nyog los hloov pH. Ib qho tsis yog tsuas yog sib xyaw ntawm cov kua qaub tsis muaj zog thiab nws lub hauv paus conjugate lossis lub hauv paus tsis muaj zog thiab nws cov conjugate acid. Buffers ua hauj lwm los ntawm reacting nrog ib qho ntxiv acid los yog hauv paus tswj pH
Thaum twg muaj zog acid yog titrated nrog lub hauv paus tsis muaj zog?
Titration ntawm lub hauv paus tsis muaj zog nrog lub zog acid. Nyob rau hauv ib qho tsis muaj zog hauv paus-muaj zog acid titration, cov kua qaub thiab lub hauv paus yuav hnov mob los tsim cov kua qaub. Lub conjugate acid yuav raug tsim thaum lub sij hawm titration, uas tom qab ntawd reacts nrog dej los tsim hydronium ions. Qhov no ua rau muaj kev daws teeb meem nrog pH qis dua 7
Yuav ua li cas koj thiaj paub yog hais tias ib tug scatter plot tsis muaj zog los yog muaj zog?
Peb hais tias muaj kev sib raug zoo tsis zoo nyob nruab nrab ntawm qhov sib txawv x thiab y. Xav txog cov nram qab no scatterplot: Peb saib tias y nce li x nce, thiab cov ntsiab lus tsis nyob ntawm txoj kab ncaj nraim. Peb hais tias ib qho kev sib raug zoo tsis muaj zog muaj nyob nruab nrab ntawm qhov sib txawv x thiab y
