Khoom muaj qhov tseeb huab hwm coj, ntim, thiab cov duab vim hais tias cov ntsiab lus ntawm teeb meem yog tuav ua ke los ntawm muaj zog intermolecular rog. Thaum tsis tshua muaj kub, lub zog intermolecular nyiam ua tus thawj lub zog thermal, lub cov khoom khib nyiab nyob twj ywm hauv lub xeev ruaj.
Ntawm no, peb yam ntxwv ntawm cov khib nyiab yog dab tsi?
A khov kho Nws muaj qhov ntim thiab cov duab meej, cov kua muaj qhov ntim meej tab sis tsis muaj qhov tseeb, thiab cov roj tsis muaj qhov tseeb ntim lossis cov duab.
Khoom
- Daim duab meej (rigid)
- Txhais ntim.
- Particles vibrate nyob ib ncig ntawm axes ruaj.
Ib yam li ntawd, cov yam ntxwv ntawm cov khoom 2 cov ntsiab lus yog dab tsi? 1) khoom muaj ib tug ruaj puab thiab lub ntim ruaj khov. 2) khoom tsis tuaj yeem compressed. 3) cov khoom muaj siab ceev. 4) quab yuam ntawm attraction ntawm cov hais yog heev muaj zog.
Tsuas yog li ntawd, dab tsi yog ib qho tseem ceeb hauv teeb meem?
Hauv ib khov kho , molecules tau ntim ua ke, thiab nws khaws nws cov duab. Cov kua dej coj cov duab ntawm lub thawv. Khoom yog ib qho ntawm peb lub xeev tseem ceeb ntawm teeb meem , nrog rau cov kua thiab roj. Teeb meem yog "khoom" ntawm lub ntiaj teb, cov atoms, molecules thiab ions uas ua rau tag nrho cov khoom ntawm lub cev.
Dab tsi yog 5 yam khoom ntawm cov khoom?
Properties of Solids
- Hluav taws xob thiab thermal conductivity.
- Malleability thiab ductility.
- Melting point.
- Solubility.

Dab tsi yog cov yam ntxwv ntawm cov khoom muaj sia?
Ib yam uas tsis muaj sia yog ib qho uas tsis muaj lossis tau tso tseg tsis pom cov yam ntxwv ntawm lub neej. Yog li, lawv tsis muaj lossis tsis pom qhov muaj peev xwm rau kev loj hlob, kev loj hlob, kev ua pa, metabolism, thiab kev txav mus los. Lawv kuj tsis muaj peev xwm teb rau stimuli los yog evolve thiab hloov mus rau lawv ib puag ncig
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Qhov twg ntawm cov no yog tus yam ntxwv ntawm txhua yam muaj sia?
Cov yam ntxwv no yog lub koom haum ntawm tes, kev yug me nyuam, metabolism, homeostasis, heredity, teb rau stimuli, kev loj hlob thiab kev loj hlob, thiab adaptation los ntawm evolution. Qee yam, xws li tus kab mob, pom tsuas yog qee yam ntawm cov yam ntxwv no thiab yog li ntawd, tsis muaj sia nyob
Dab tsi ntawm lub cev nta yog cov yam ntxwv ntawm cov ntug dej hiav txwv ntawm Texas?
Texas 'Gulf Coastal Plains yog sab hnub poob txuas ntxiv ntawm ntug hiav txwv tiaj tiaj txuas los ntawm Dej Hiav Txwv Atlantic mus dhau Rio Grande. Nws cov yam ntxwv dov mus rau toj roob hauv pes npog nrog kev loj hlob hnyav ntawm ntoo thuv thiab tawv ntoo txuas mus rau East Texas
Hom kev sib txuas dab tsi yog yam ntxwv ntawm cov khoom uas muaj qhov kub siab melting point?
Ionic lattice Tag nrho cov ionic tebchaw muaj lub siab melting point thiab boiling point vim hais tias muaj ntau zog ionic bonds yuav tsum tau tawg. Lawv ua thaum molten los yog nyob rau hauv kev daws raws li cov ions yog dawb txav. Lawv tuaj yeem tawg los ntawm electrolysis. Lawv feem ntau yog soluble hauv dej
