Faahfaahinta casharka

Natiijada casharka

I can describe and explain what happens when a substance changes state and how evaporation occurs.

Muuji qoraalka

States of matter can have differing amounts of energy. Solid states have the least energy, gas states have the most energy. A substance in its liquid state can evaporate at temperatures below its boiling point. The hotter the water, the more quickly it evaporates. Water evaporates at temperatures that are lower than 100℃.

Imtixaannada

1. Waa kee xaaladda maaddada (state of matter) aan lahayn qaab go'an, laakiin leh mug go'an (definite volume) oo qaadi kara socod (flow)?
- Jawaabta saxda ah:a, dareere (liquid)
- b, adke (solid)
- c, gaas (gas)
2. Waa kee gobolka (state) uu ugu yar yahay xoogagga soo jiidashada (forces of attraction) ee u dhexeeya walxaha (particles)?
- adag (solid)
- dheecaanka (liquid)
- Jawaabta saxda ah:gaas (gas)
3. Waa keene gobolka maadarka (state of matter) ee muggiisu isbeddelo marka la cadaadiyo (compress)?
- adag (solid)
- dareere (liquid)
- Jawaabta saxda ah:gaas (gas)
4. Labaha beaker-ka ee hoos ku qoran, oo isla qadarka biyaha ku jira, ayaa lagu daayay qol. Dooro **dhammaan** jumladaha runta ah ee ku saabsan **Beaker A**.
- Marka hore ayuu qallalaa.
- Jawaabta saxda ah:Bedka biyaha oo ka yar kan kale.
- Jajabka atamka (particles) ee dusha sare oo la taabanaya hawada ayaa ka yar.
- Wuu ka ballaadhan yahay beaker-ka kale.
- Biyuhu waxay ku fidsan yihiin aag ka weyn.
5. Waa xilliga jiilaalka. Weelka shimbiraha ee beerta dugsigu wuxuu u baahan yahay in dib loo buuxiyo. Carruurta dugsiga hoose waxay ka wada hadlayaan in uumibixu (evaporation) noqon karo sababta weelka shimbirahu u maran yahay. Kee baa ah sababta saxda ah?
- Qorraxdu uma xoog badna inay qalajiso weelka shimbiraha xilliga jiilaalka.
- Qorraxdu waxay uumisaa biyaha xilliga xagaaga laakiin ma awoodi karto jiilaalka.
- Weli waxaa jira maalmo qorrax leh oo jiilaalka ah kuwaas oo qalajin kara weelka shimbiraha.
- Jawaabta saxda ah:Biyuhu wali way uumi karaan xitaa haddii cimiladu aanay qorrax lahayn.

1. Biyuhu waxay uumi karaan heerkulka ka hooseeya 100℃.
- Jawaabta saxda ah:Run
- Been
2. Maxaa ku dhacaya tamarta walaxda markay iska beddelayso gaas (gas) una beddelanayso dareere (liquid)?
- Jawaabta saxda ah:Waa hoos u dhacdaa.
- Waa kor u kacdaa.
- Waa isku mid ahaanaysaa.
3. Waa kee labada shay ee sida caadiga ah loogu isticmaalo heerkulbeegyada (thermometers) oo ay awoodaan inay beddelaan xaaladdooda heerkul hoose?
- biyo
- Jawaabta saxda ah:meerkuri (mercury)
- khamri (alcohol)
- cusbo-biyood (salt solution)
4. Arday qaar ayaa dib u eegaya farqiga u dhexeeya karkarinta (boiling) iyo uumiga (evaporating), waxayna isku khaldeen kaararka dib u eegista. Dooro **dhamaan** weedhaha hoose ee ku saabsan uumiga (evaporation).
- Jawaabta saxda ah:Dareere waa la kululeeyaa oo muggiisu wuu yaraadaa, laakiin xumbo gaas ah ma samaysmaan.
- Biyo daadanayay qaar ayaa ku engega qol qabow.
- Hab dhacaya heerkul kasta oo ka sarreeya barta dhalaalidda (melting point).
- Baasto lagu karinayo dheri biyo ah oo soo saaraya xumbo gaas ah oo badan.
- Sameynta gaas ka yimaada dareere, laakiin waa in la gaaraa heerkul gaar ah.
