Vim calorimetry yog siv los ntsuas qhov kub ntawm cov tshuaj tiv thaiv, nws yog ib feem tseem ceeb ntawm thermodynamics. Txhawm rau ntsuas qhov kub ntawm cov tshuaj tiv thaiv, cov tshuaj tiv thaiv yuav tsum tau cais tawm kom tsis txhob muaj cua sov poob rau ib puag ncig. Qhov no yog tiav los ntawm siv ntawm a calorimeter , uas insulates cov tshuaj tiv thaiv kom zoo dua muaj cua sov.
Thiab cov lus nug yog, dab tsi yog qhov kev siv ntawm calorimeter?
A calorimeter yog ib qho cuab yeej siv hauv calorimetry rau kev ntsuas cov cua sov tso tawm los yog absorbed nyob rau hauv tshuaj lom neeg los yog lub cev cov tshuaj tiv thaiv. Nws tuaj yeem txiav txim siab cov ntsiab lus ntawm cov cua sov, cov cua sov latent, cov cua sov tshwj xeeb, thiab lwm yam khoom siv thermal ntawm cov khoom.
Kuj Paub, lub hom phiaj ntawm lub khob kas fes hauv kev sim calorimetry yog dab tsi? Cov khob kas fes insulates cov kev sim , minimizing tshav kub poob rau ib puag ncig. Sau cov kev taw qhia ntawm cov cua kub ntws ntawm qhov system thiab ib puag ncig rau txhua tus txheej txheem.
Kuj Paub, 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.
Lub hom phiaj ntawm calorimetry lab yog dab tsi?
Lub hom phiaj . Txhawm rau txiav txim siab seb lub khob Styrofoam calorimeter muab cov rwb thaiv tsev tsim nyog rau kev ntsuas kev hloov hluav taws xob, txhawm rau txheeb xyuas cov hlau tsis paub los ntawm txoj kev ntawm nws lub peev xwm kub thiab txiav txim siab qhov kub ntawm qhov nruab nrab thiab qhov kub ntawm kev daws.

Vim li cas cov txheej txheem ntawm cov protein synthesis tseem ceeb rau lub neej?
Protein synthesis yog cov txheej txheem tag nrho cov hlwb siv los ua cov protein, uas yog lub luag haujlwm rau tag nrho cov qauv ntawm tes thiab kev ua haujlwm. Proteins tseem ceeb hauv txhua lub hlwb thiab ua haujlwm sib txawv, xws li koom nrog cov pa roj carbon dioxide rau hauv qab zib hauv cov nroj tsuag thiab tiv thaiv cov kab mob los ntawm cov tshuaj phem
Vim li cas lub voj voog carbon tseem ceeb rau lub neej?
Cov pa roj carbon monoxide yog qhov tseem ceeb hauv ecosystems vim tias nws txav cov pa roj carbon monoxide, uas yog lub luag haujlwm txhawb nqa lub neej, los ntawm huab cua thiab dej hiav txwv mus rau cov kab mob thiab rov qab mus rau huab cua thiab dej hiav txwv. Cov kws tshawb fawb tam sim no tab tom nrhiav txoj hauv kev uas tib neeg tuaj yeem siv lwm yam, tsis muaj cov pa roj carbon uas muaj roj rau lub zog
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Vim li cas peb thiaj siv cov lej tseem ceeb hauv chemistry?
Cov lej tseem ceeb (tseem hu ua tus lej tseem ceeb) yog ib feem tseem ceeb ntawm kev suav lej tshawb fawb thiab lej, thiab cuam tshuam nrog qhov raug thiab raug ntawm cov lej. Nws yog ib qho tseem ceeb rau kev kwv yees qhov tsis paub tseeb ntawm qhov kawg tshwm sim, thiab qhov no yog qhov tseem ceeb ntawm cov duab los ua qhov tseem ceeb heev
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
