Faahfaahinta casharka

Natiijada casharka

I can predict the resulting temperature when two substances of different temperatures are put together.

Muuji qoraalka
Mixing hot water with cold water results in water cooler than the hot water and warmer than the cold. When hot and cold water are mixed, the temperature is closer to that of the water there was more of. A cold object placed in hot water makes the water particles move more slowly and those in the object move more quickly. A hot object placed in cold water makes the water particles move more quickly and those in the object move more slowly.

    • conical flask (dhalo qaab toorey ah)
    • Jawaabta saxda ah:measuring cylinder (dhululubo qiyaas)
    • test tube (tuubo tijaabo)

  2. 2. Waa keet xaalad (state) oo walaxda (matter) ah oo ay qaybaha biyuhu (particles) u dhaqaaqaan si ugu dhaqsaha badan?

    • adag (solid)
    • dareere (liquid)

    • Jawaabta saxda ah:waxay taabtaan midba midka kale
    • isku dhow yihiin, laakiin qaar baa taabtay
    • isku dhow yihiin, meel bannaan oo yar ayaa u dhexeysa mid kasta
    • kala firdhiyeen, meelo bannaan oo waaweyn ayaa u dhexeysa

  4. 4. Maxaa ku dhacaya walxaha (particles) ka samaysan gaas marka la kululeeyo heerkul sare?

    • Waxay dhaqaaqaan xawaare isku mid ah.
    • Waxay dhaqaaqaan xawaare isku mid ah oo way kala fogaadaan.
    • Waxay dhaqaaqaan si ka dhakhso badan.
    • Jawaabta saxda ah:Waxay dhaqaaqaan si ka dhakhso badan oo way kala fogaadaan.

  5. 5. Maxay tahay sababta taabashada bir adag oo aad u kulul ay gubto maqaarkaaga?

    • Jawaabta saxda ah:Qaybaheeda (particles) waxay si degdeg ah ugu wareejiyaan tamarta maqaarkaaga, taasoo waxyeelleysa unugyada maqaarka.
    • Qaybaheeda ayaa si degdeg ah u dhaqaaqaya, taasoo waxyeelleysa unugyada maqaarka.
    • Qaybaheeda ayaa si degdeg ah u kala fidsanaya, taasoo waxyeelleysa unugyada maqaarka.

    • 40°C
    • Jawaabta saxda ah:60°C
    • 80°C
    • Ma suurtogal in la saadaaliyo.

  2. 2. 100 cm³ oo biyo ah oo heerkoodu yahay 60°C ayaa lagu daray 50 cm³ oo biyo ah oo heerkoodu yahay 30°C. Waa maxay heerka (temperature) ugu dambeeysa ee isku darka?

    • 30°C

    • 80°C
    • 70°C
    • 60°C
    • Jawaabta saxda ah:50°C
    • 40°C

  4. 4. Maxaa dhacaya marka walxaha (particles) dhaqsiyo badan ee adke (solid) kulul ay isku dhacaan walxaha gaabiska ah ee dareere (liquid) qabow?

    • Jawaabta saxda ah:Celcelis ahaan, walxaha adkaha ayaa gaabiya.
    • Celcelis ahaan, walxaha adkaha ayaa dhaqsiyeeya.
    • Celcelis ahaan, walxaha dareeraha ayaa gaabiya.
    • Celcelis ahaan, walxaha dareeraha ayaa dhaqsiyeeya.

  5. 5. Maxay tahay sababta uu barafku (cube-ka biyaha adag) u dhalaalo marka la geliyo galaas liin macaan (lemonade) oo heerkulkiisu yahay heerkulka qolka?

    • Walxaha (particles) ee liin macaanu waxay keenaan in walxaha biyuhu kala go'aan.
    • Walxaha liin macaanu waxay keenaan in walxaha biyuhu dhalaalaan.
    • Jawaabta saxda ah:Walxaha liin macaanu waxay keenaan in walxaha biyuhu si degdeg ah u dhaqaaqaan.
    • Walxaha liin macaanu waxay keenaan in walxaha biyuhu is yimaadaan (shrink).
