Cov cov khoom txav tsis tau ib ncig. Ib qho piv txwv ntawm ob qho tib si khib nyiab thiab kua yog qhov cov khoom muaj kev sib cuag nrog lawv cov neeg zej zog, uas yog, nrog rau lwm tus cov khoom . Yog li ntawd lawv yog incompressible thiab no commonality nruab nrab khoom thiab kua distinguishes lawv los ntawm gases.
Ntxiv rau qhov no, qhov chaw nruab nrab ntawm cov khoom hu ua dab tsi?
nws yog hu ua intermolecular qhov chaw muaj nyob rau hauv nruab nrab ntawm qhov teeb meem.
Tom qab ntawd, lo lus nug yog, puas yog cov khoom txav? Cov cov khoom txawm li cas los xij, tseem nyob hauv kev txav mus los. Cov khoom nyob rau hauv cov khoom yog ib txwm vibrating ( tsiv rov qab) nyob rau hauv qhov chaw. Lub vibrational txav ntawm cov khoom insolids yog kinetic zog. Thaum tshav kub kub ua rau cov khoom nyob rau hauv asolid vibrate sai, muab lawv ntau kinetic zog.
Tsis tas li ntawd, cov particles txav li cas?
Cov cov khoom nyob rau hauv ib qho khoom yog nruj nreem ntim thiab kaw rau hauv qhov chaw. Cov cov khoom nyob rau hauv cov kua yog nyob ze (kov) tab sis lawv muaj peev xwm txav /slide/flowpast ib leeg. Cov cov khoom nyob rau hauv ib tug gas yog ceev tsiv thiab muaj peev xwm sib txawv ntawm ib leeg.
Cov yam ntxwv ntawm cov khoom yog dab tsi?
Cov yam ntxwv ntawm particles ntawm Matter:
- Cov khoom ntawm cov khoom yog heev, tsawg heev.
- Cov khoom ntawm cov khoom muaj qhov chaw nruab nrab ntawm lawv.
- Cov khoom ntawm cov khoom yog txav mus tas li.
- Cov khoom ntawm cov khoom sib txuas.

Qhov nruab nrab nruab nrab ntawm lub ntiaj teb yog dab tsi?
Lub teb chaws qhov ntsuas kub yog 2.91 ° C (5.24 ° F) saum toj no 1961-1990 qhov nruab nrab, tawg cov ntaub ntawv yav dhau los tau teev tseg hauv 2013 los ntawm 0.99 ° C (1.78 ° F)
Koj pom qhov nruab nrab thiab nruab nrab hauv tableau li cas?
Kev sib txuas lus cov ntaub ntawv nrog Tableau los ntawm Ben Jones Qhov nruab nrab (lossis nruab nrab) yog txiav txim siab los ntawm kev suav tag nrho cov txiaj ntsig hauv cov ntaub ntawv teev thiab faib los ntawm tus lej ntawm qhov tseem ceeb. Qhov nruab nrab yog tus nqi nruab nrab hauv cov ntaub ntawv teev nyob rau hauv uas qhov tseem ceeb tau muab tso rau hauv kev txiav txim ntawm qhov loj
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
Koj ua li cas sib npaug redox cov tshuaj tiv thaiv hauv acidic thiab nruab nrab nruab nrab?
Acid Conditions Solution. Kauj Ruam 1: Sib cais ib nrab cov lus teb. Kauj Ruam 2: Ntsuas cov ntsiab lus uas tsis yog O thiab H. Kauj Ruam 3: Ntxiv H2O kom sib npaug ntawm cov pa. Kauj Ruam 4: Sib npaug hydrogen los ntawm kev ntxiv protons (H +). Kauj Ruam 5: Ntsuas tus nqi ntawm txhua qhov sib npaug nrog electrons. Kauj Ruam 6: Ntsuas cov tshuaj tiv thaiv kom cov electrons sib npaug
