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.
Tib neeg kuj nug, dab tsi yog qhov system thiab ib puag ncig?
Cov qhov system muaj cov molecules uas yog reacting. Cov ib puag ncig yog txhua yam; lub qab ntuj khwb. Piv txwv li, hais tias cov tshuaj tiv thaiv saum toj no tshwm sim hauv cov pa roj; ces cov phab ntsa ntawm lub thawv yog ib feem ntawm ib puag ncig.
Dab tsi yog qhov system thiab ib puag ncig hauv cov tshuaj tiv thaiv neutralization? Yog li ntawd nyob rau hauv ib tug neutralization tshuaj tiv thaiv , cov qhov system yog qhov tseeb acid thiab puag thaum lub ib puag ncig yog cov kuab tshuaj (dej). Vim nws yog exothermic tshuaj tiv thaiv , qhov no txhais tau hais tias lub zog tawm ntawm lub qhov system mus rau ib puag ncig.
Ib yam li ntawd ib tug yuav nug, hom kev kaw lus twg yog calorimeter?
Ib lub foob pob calorimeter yog kaw qhov system vim nws tso cai rau cua sov sib pauv. Thaum no qhov system yog insulated, "insulated qhov system " tsis yog ib qho ntawm peb lub ntsiab hom tshuab : kaw, qhib, thiab cais.
Puas yog dej ib feem ntawm qhov system lossis ib puag ncig?
Xav txog qhov xwm txheej ntawm qhov tshwm sim tshwm sim ntawm cov dej reactants. Cov dej nyob rau hauv uas cov solids tau yaj yog cov ib puag ncig , thaum lub yaj tshuaj yog cov qhov system.

Dab tsi yog qhov txawv ntawm ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
A. Ib puag ncig lapse tus nqi yog hais txog qhov kub thiab txias nrog nce qhov siab hauv troposphere; uas yog qhov kub ntawm ib puag ncig ntawm qhov chaw sib txawv. Nws implies tsis muaj huab cua txav. Adiabatic txias tsuas yog cuam tshuam nrog huab cua ascending, uas txias los ntawm kev nthuav dav
Dab tsi yog qhov txawv ntawm ib puag ncig kev hloov pauv thiab kev hloov pauv qub txeeg qub teg?
Qhov sib txawv ntawm cov yam ntxwv ntawm cov tib neeg ntawm tib hom yog hu ua variation. Qhov no yog inherited variation. Qee qhov kev hloov pauv yog qhov tshwm sim ntawm qhov sib txawv ntawm ib puag ncig, lossis ib tus neeg ua dab tsi. Qhov no yog hu ua environmental variation
Dab tsi yog qhov cuam tshuam ib puag ncig ntawm kev rho tawm thiab siv cov peev txheej ntxhia?
Qee qhov kev cuam tshuam loj ntawm ib puag ncig ntawm kev khawb thiab kev ua cov khoom siv pob zeb muaj raws li hauv qab no: 1. Cov pa phem 2. Kev cuam tshuam hauv zej zog los ntawm kev xav tau ntau ntxiv rau vaj tse thiab lwm yam kev pabcuam hauv thaj chaw mining. Cov pa phem: Kev puas tsuaj ntawm av: Kev poob qis: Suab nrov: Lub zog: Kev cuam tshuam rau ib puag ncig lom neeg:
Dab tsi yog qhov cuam tshuam ib puag ncig ntawm chav tsev thiab pillar mining?
Chav thiab pillar mining yog ib txoj kev npaj uas tsis yog-subsidence rau ib lub mine, khaws cia thaj av muaj nuj nqis saum toj no. Nws yog ib qho kev nyab xeeb tshaj plaws thiab yog ib txoj hauv kev zoo tshaj plaws rau kev ua haujlwm mining thee niaj hnub no, tsim kom muaj ib puag ncig tsis zoo (tsis muaj kev txav ntawm av) thiab tswj cov qauv dej huv
Dab tsi yog qhov ib puag ncig qhuav thiab noo adiabatic lapse tus nqi?
Qhov thib ib, qhov qhuav adiabatic lapse tus nqi, yog tus nqi ib qho unsaturated parcel ntawm huab cua sov los yog txias thaum tsiv vertically los ntawm cov cua. Qhov moist adiabatic lapse tus nqi, ntawm qhov tod tes, yog tus nqi ntawm cov khoom noj uas muaj cua sov los yog txias thaum nws txav mus los
