Ntim yog ib qho kev ntsuas seb qhov chaw qhov khoom siv li cas. Rau piv txwv ob lub thawv khau ua ke muaj ob zaug ntim ntawm ib lub thawv, vim lawv siv li ob npaug ntawm qhov chaw. Rau piv txwv , nyob rau hauv ib lub voos xwmfab peb pom cov ntim los ntawm kev muab peb sab ntev ua ke. Nyob rau hauv lub kub saum toj no, lub ntim yog 3x3x27.
Tsis tas li ntawd, qee qhov piv txwv ntawm ntim yog dab tsi?
Ntim yog qhov ntau ntawm peb qhov chaw nyob los ntawm cov kua, khoom, lossis roj. Common units siv los qhia ntim suav nrog litres, cubic meters, nkas loos, milliliters, teaspoons, thiab ounces, txawm tias muaj ntau lwm units.
dab tsi yog ib qho piv txwv ntawm ntim? A. Cov iav yog ib nrab puv yog ib qho piv txwv ntawm ntim . Lub iav yog ib nrab khoob yog ib qho piv txwv ntawm tsis yog - ntim . C. Ib nplooj ntawv dawb yog a tsis yog - piv txwv ntawm txhua yam suav nrog ntim.
Yog li ntawd, dab tsi yog ntim hauv cov lus yooj yim?
Ntim hais txog qhov chaw qhov khoom siv li cas. Hauv lwm yam lus , ntim yog ib qho kev ntsuas qhov loj ntawm ib yam khoom, ib yam li qhov siab thiab qhov dav yog txoj hauv kev los piav txog qhov loj. Yog tias cov khoom yog hollow (hauv lwm yam lus , npliag), ntim yog cov dej uas nws tuav tau.
Qhov ntim ntawm ib yam khoom yog dab tsi?
Ntim yog tus nqi ntawm qhov chaw ib khoom occupies thaum ceev yog qhov loj ntawm ib khoom ib chav ntim . Common units rau ntim yog cubic centimeters (cm3), cubic meters (m3), cubic inches (in3), thiab cubic feet (ft3). Thaum koj muaj ntim , qhov ceev yog ib qho yooj yim rau kev xam tam sim ntawd.

Nws yog qee zaum tsis meej pem nrog cov qauv ntawm qhov kev sim, feem ntau yog los ntawm omega (Ω), tab sis txawv: thaum lub sij hawm qhov chaw ntawm qhov kev sim muaj tag nrho cov txiaj ntsig tau, qhov chaw tshwm sim muaj tag nrho cov txiaj ntsig tau tshwm sim; tag nrho cov subsets ntawm cov qauv qhov chaw
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
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
