a. Hlau yog zoo heev conductors ntawm tshav kub. Yog tias tom qab tshem lub raj nrog hlau los ntawm cov dej kub da dej, koj tsis kam ua ntej dumping hlau rau hauv calorimeter , cov hlau yuav tsis nyob ntawm qhov kub ntawm cov dej npau. Yog li ntawd, cov dej nyob hauv calorimeter yuav rhuab mus rau qhov kub thiab txias.
Xav txog qhov no, vim li cas koj thiaj li yuav tsum hloov cov hlau sai sai ntawm cov dej kub npau npau rau hauv calorimeter?
Lub tshav kub zog absorbed los yog tso tawm los ntawm lub dej yog nyob ntawm qhov loj ntawm lub dej . Vim li cas koj thiaj li yuav tsum tau hloov cov hlau sai sai los ntawm qhov kub dej da dej rau dej hauv lub khob styrofoam calorimeter ? Vim qhov tsawg kawg nkaus ntawm cov cua sov yog poob los ntawm hlau rau hauv huab cua & ib zaug lub hlau yog tshem tawm.
Ib tug kuj yuav nug, dab tsi yog qhov system thiab ib puag ncig hauv lub calorimeter? Calorimeter . Cov qhov system yog ib feem ntawm lub qab ntuj khwb tau kawm, thaum lub ib puag ncig yog lwm lub ntiaj teb uas cuam tshuam nrog cov qhov system . Calorimeter yog ib qho cuab yeej siv los ntsuas qhov muaj nuj nqis ntawm lub zog hloov hauv lub qhov system xws li tshuaj tiv thaiv.
Ib tug kuj yuav nug, dab tsi yog qhov ua tau yuam kev hauv kev sim calorimetry?
Qhov feem pua yuam kev rau qhov no kev sim yog 24.4%. Qhov chaw ntawm qhov yuam kev rau qhov no lab suav nrog calorimeters rwb thaiv tsev, tsis tiav combustion ntawm paraffin, thiab rwb thaiv tsev ntawm combustion ntawm paraffin. Ob chav-Styrofoam khob calorimeter tsis yog ib qho kaw tag nrho vim lub qhov rau saum.
Dab tsi yog qhov tseem ceeb tshaj plaws ntawm calorimeter?
Ib qho yooj yim calorimeter tsuas yog muaj tus pas ntsuas kub uas txuas rau lub thawv hlau uas muaj cov dej tshem tawm saum lub combustion chamber. Raws li qhov no, lub qhov tseem ceeb tshaj plaws yuav yog lub tshav kub fusion ntawm dej, yeej vim hais tias tus nqi no yuav nyob twj ywm tib yam tsis hais cov zaub mov koj siv cov hlau.

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
Yuav ua li cas tshwm sim rau ib lub caij thaum nws dhau mus beta lwj?
Beta lwj tshwm sim thaum lub nucleus tsis ruaj khov emitsa beta particle thiab lub zog. Ib qho beta particle yog ob qho tib si electron lossis positron. A: Hauv beta-minus decay anatom nce ib proton, thiab nws beta-ntxiv lwj nws lossa proton. Nyob rau hauv txhua rooj plaub, lub atom ua ib tug sib txawv vim hais tias nws muaj ib tug txawv tus naj npawb ntawm protons
Yuav ua li cas tshwm sim rau lub parallel phaj capacitor thaum lub dielectric muab tso rau ntawm daim hlau?
Thaum cov khoom siv dielectric tau qhia nruab nrab ntawm daim hlau Thiab thaum cov khoom siv dielectric muab tso rau nruab nrab ntawm daim hlau ntawm cov paib sib npaug ntawm cov phaj capacitor ces vim polarization ntawm cov nqi ntawm ob sab ntawm dielectric, nws tsim hluav taws xob teb ntawm nws tus kheej uas ua nyob rau hauv ib qho kev taw qhia opposite. rau lub teb vim
Yuav ua li cas tshwm sim thaum lub zog pauv ntawm ib yam khoom mus rau lwm tus?
Lub zog yog pauv los ntawm ib qho khoom mus rau lwm qhov thaum muaj qhov tshwm sim tshwm sim. Lub zog los ntawm ntau hom thiab tuaj yeem hloov los ntawm ib yam khoom mus rau lwm qhov xws li cua sov, lub teeb, lossis kev txav mus los, rau npe ob peb. Daim ntawv ntawm lub zog no hu ua kinetic zog
Yuav ua li cas tshwm sim thaum dilute sulfuric acid ntxiv rau hlau sulfide?
A. Thaum twg ?dilute sulfuric acid ntxiv rau kev sib xyaw ntawm cov hlau txhaws thiab cov hmoov sulfur, cov tshuaj tiv thaiv occusrs ntawm dilute sulfuric acid thiab hlau filings uas tsim ferrous sulphate thiab evolution ntawm hydrogen. FeS tsim reacts nrog sulfuric acid los tsim ferrous sulphate thiab tso tawm hydrogendisulphide gas
