Cov hais tias tag nrho cov cov khoom uas ua teeb meem tas li nyob rau hauv tsab ntawv tsa suab . Yog li ntawd, tag nrho cov khoom hauv teeb meem muaj kinetic zog. Lub kinetic txoj kev xav ntawm teeb meem pab piav qhia lub xeev sib txawv ntawm teeb meem - Khoom, kua, thiab roj. Cov khoom tsis txhob txav ntawm tib lub nrawm.
Ib yam li ntawd, ib tug yuav nug, vim li cas cov khoom ntawm cov teeb meem txuas mus ntxiv?
Cov khoom nyob rau hauv txhua lub xeev ntawm teeb meem nyob tas li tsab ntawv tsa suab thiab qhov no yog ceev heev ntawm chav tsev kub. Qhov kub thiab txias nce lub kinetic zog thiab ceev ntawm cov khoom ; nws tsis ua rau lub zog nruab nrab ntawm lawv. Tus kheej cov khoom nyob rau hauv cov kua thiab gases tsis muaj txoj hauj lwm ruaj thiab txav chaotically.
Kuj Paub, ua li cas cov khoom txav? Particles nyob rau hauv ib tug:
- roj vibrate thiab txav mus los ntawm kev kub ceev.
- kua vibrate, txav mus, thiab swb dhau ib leeg.
- khoom vibrate (jiggle) tab sis feem ntau tsis txav ntawm qhov chaw mus rau qhov chaw.
Qhov thib ob, puas yog cov ntsiab lus ntawm cov teeb meem txav qhov nruab nrab ntawm lawv teb?
Cov cov khoom txav tsis tau ib ncig. Ib qho tshwj xeeb ntawm cov khoom khib nyiab thiab cov kua dej yog qhov cov khoom muaj kev sib cuag nrog lawv cov neeg zej zog, uas yog, nrog rau lwm tus cov khoom . Yog li lawv yog incompressible thiab no commonality nruab nrab khoom thiab kua distinguishes lawv los ntawm gases.
Dab tsi yog qhov nruab nrab ntawm cov teeb meem?
Cov cov khoom tuaj yeem txav mus los thiab sib xyaw nrog lwm tus cov khoom . Yog li ntawd, cov kua yuav hloov cov duab kom phim lawv lub thawv. Tseem muaj chaw me me heev nruab nrab hais , yog li cov kua kuj nyuaj rau compress. Hauv gases cov khoom sib nrug ntau dua li cov khoom khib nyiab lossis kua.

Puas yog nws muaj tseeb tias nyob rau hauv kev thauj mus los ntawm kev txav ntawm cov khoom hla ib daim nyias nyias yuav tsum muaj zog?
Hauv kev thauj mus los passive, kev txav ntawm cov khoom hla ib daim nyias nyias yuav tsum muaj zog. _ Muaj tseeb_ 5. Endocytosis yog ib txoj kev uas ib lub cell membrane nyob ib puag ncig thiab siv cov khoom los ntawm ib puag ncig. Ib daim nyias nyias uas tso cai rau qee cov ntaub ntawv dhau los qhia txog kev xaiv permeability
Dab tsi yog lub zog uas tuaj yeem tshwm sim ntawm qhov chaw ua si los ua kom cov khoom pib txav mus los?
Kev sib txhuam. Thaum lub ntiajteb txawj nqus yog ib qho tseem ceeb ntawm physics rau qhov chaw ua si swb, kev sib txhuam yog qhov tseem ceeb sib npaug. Kev sib txhuam ua haujlwm tiv thaiv lub ntiajteb txawj nqus kom qeeb tus neeg qhovntsej thiaj tsis mob ntawm tus swb. Kev sib txhuam yog ib qho quab yuam uas tshwm sim thaum twg ob yam khoom rub tawm rau ib leeg, xws li swb thiab ib tus neeg lub nraub qaum
Koj puas tuaj yeem ua kom cov khoom ntawm tej yam tsis txav mus los?
Cov khoom tsis tuaj yeem txav mus los ntawm txhua qhov. Cov hais, txawm li cas los xij, tseem nyob hauv kev txav mus los. Cov khoom hauv cov khib nyiab yeej ib txwm vibrating (tsav rov qab thiab tawm) nyob rau hauv qhov chaw. Lub vibrational txav ntawm cov khoom hauv cov khoom yog kinetic zog
Puas yog cov pa roj ib txwm txav mus los?
Cov lus hais tias tag nrho cov khoom uas ua rau muaj teeb meem tas li nyob rau hauv kev txav mus los. Yog li ntawd, tag nrho cov hais nyob rau hauv cov teeb meem muaj kinetic zog. Lub kinetic txoj kev xav ntawm cov teeb meem pab piav qhia txog cov xwm txheej sib txawv - khoom, kua, thiab roj. Cov khoom tsis tas yuav txav mus rau tib lub nrawm
Puas yog atoms ua los ntawm cov ntsiab lus los yog cov khoom tsim tawm ntawm atoms?
Atoms yeej ib txwm ua los ntawm cov khoom. Atoms qee zaum ua los ntawm cov khoom. Lawv txhua tus muaj ob tsab ntawv hauv lawv cov cim atomic. Cov muaj pes tsawg leeg
