Faahfaahinta casharka

Natiijada casharka

I can explain how particles spread through a fluid.

Muuji qoraalka
Brownian motion is the random motion of particles suspended in a medium. Particles of a substance released into a fluid (a gas or liquid) move around and are pushed by other particles. Substances that have particles that are free to move will eventually reach a random distribution throughout. At higher temperatures, particles in a gas or solution move more quickly.

Imtixaannada

  1. 1. Waa keene xaaladda maaddada (state of matter) ay walxaha (particles) isu jiraan masaafada ugu dheer?

    • adag (solid)
    • dareere (liquid)
    • Jawaabta saxda ah:gaas (gas)

  2. 2. Waa kuwee kuwan waxyaabaha isku dhafan (mixtures)?

    • oksijiin (oxygen)
    • Jawaabta saxda ah:hawada (air)
    • cabitaanka liinta (orange squash)
    • biyo saafi ah (pure water)
    • kaarboon dioxide (carbon dioxide)

  3. 3. Haddii gaas (gas) la geliyo weel, maxaad filan lahayd in ay sameeyaan jajabyada gaasku?

    • Jajabyadu waxay isu soo ururi lahaayeen dhinac keliya oo weelka ah.
    • Jajabyadu waxay hoos u degi lahaayeen salka weelka.
    • Jawaabta saxda ah:Jajabyadu waxay ku fidi lahaayeen inay buuxiyaan weelka oo dhan.

  4. 4. Waa maxay habka saxda ah ee loo muujiyo inta solute (walaxda lagu milay) la isticmaalay iyadoo la isticmaalayo 145.63 g oo biyo ah si loo sameeyo xal (solution) leh cuf (mass) 147.59 g?

    • 147.59 + 145.63 = cufka solute
    • cufka solute = 145.63 - 147.59
    • Jawaabta saxda ah:cufka solute = 147.59 - 145.63
    • 145.63 x 147.59 = cufka solute

  1. 1. Waa ereygee ku habboon in lagu qeexo marka ay wax dhacaan iyada oo aan lahayn qaab cad oo la saadaalin karo?

    • casual (aan rasmi ahayn)
    • particular (gaar ah)
    • specific (khaas ah)
    • Jawaabta saxda ah:random (aan qaab lahayn)

  2. 2. Mid ka mid ah kuwan soo socda ayaa ah hadal run ah oo ku saabsan sida ugu dhakhsaha badan ee uu diffusion u dhaco?

    • Kaliya heerkulka (temperature) ee dhexdhexaadka (medium) ayaa saameyn ku yeelan doona.
    • Kaliya heerkulka walxaha faafaya (diffusing substance) ayaa saameyn ku yeelan doona.
    • Jawaabta saxda ah:Heerkulka labadaba, walxaha faafaya iyo dhexdhexaadka, ayaa saameyn ku yeelan doona.
    • Heerkulku ma saameynayo sida uu diffusion u dhaco.

  3. 3. Dhameystir 3 jumlado oo qeexaya waxa sawirka ku dhacaya: Qaybaha khadka iyo biyaha waxay u dhaqaaqayaan ____. Waxay ____ isku yimaadaan taasina waxay keentaa inay isku qasmaan. Khadku wuxuu ____ biyaha dhex maraa.

    • ma, ku dhacaan, faafaan
    • Jawaabta saxda ah:si xor ah, isku dhacaan, faafaan
    • si xor ah, burburaan, isku cadaadiyaan
    • ma, isku dhacaan, faafaan
