Faahfaahinta casharka

Natiijada casharka

I can compare data involving the solubility of different solutes and use it to describe saturation.

Muuji qoraalka

At a given temperature, there is a limit to how much solute can dissolve in a solvent. Solutes may become insoluble as a solution cools. Lines of best fit can be used to predict unknowns values if one variable is known. Data from multiple investigations can be plotted on the same graph for ease of comparison.

Imtixaannada

1. Maxaa dhacaya inta badan solute-yada (solutes) marka heerkulka (temperature) dareeraha (solvent) uu kordho?
- Jawaabta saxda ah:Waxay ku milmaan si dhakhso ah.
- Waxay noqdaan kuwo aan milmi karin (insoluble).
- Cufkooda (mass) wuu kordhaa.
- Waxay uumaan (evaporate) la dareeraha.
2. Marka aad sawirto garaaf (graph) cilmiga sayniska, kee ka mid ah garaafyadan ayaa doorsoomayaashiisa (variables) si sax ah loo dhigay?
- Jawaabta saxda ah:Garaafka leh xariiq toosan oo muujinaya doorsoomaha madaxbannaan (independent variable)
- Jaantuska (bar chart) tusaya tirada noocyada kala duwan ee doorsoomaha
- Garaafka leh xariiq toosan oo ka siman xariiq kale oo ka siman xariiq kale
- Jaantuska (bar graph) tusaya tirada doorsoomaha madaxbannaan (independent variable)
3. Maxaa caadi ahaan loo isticmaalaa sayniska si loo saadaaliyo qiimaha ka imanaya garaafka?
- Jawaabta saxda ah:Khadka ugu habboon (line of best fit).
- Magacyada dhinacyada (axis labels).
- Cinwaanka garaafka.
- Qiimaha celceliska (mean) ka hor inta aan la sawirin.
- Jaantuska tiirarka (bar chart).
4. Milmi ahaanshuhu waa sharaxaad ku saabsan sida ugu fiican ee dareeraha (solvent) ugu milmi karo walaxda lagu milo (solute).
- run
- Jawaabta saxda ah:been

1. Waa maxa indha-indheyn (observation) muujinaysa in xal (solution) uu noqday mid dheregsan (saturated)?
- Xalku wuxuu noqdaa mid kulul.
- Jawaabta saxda ah:Walaxda milanta (solute) oo aan milmin ayaa haraa.
- Milanka (solvent) wuxuu beddelaa midabkiisa.
- Xalku wuxuu bilaabaa inuu xumbo (bubble) soo saaro.
2. Khadka ugu habboon ee garaafka milanka waxaa loo isticmaali karaa in lagu saadaaliyo milanka walaxda (solute) heerkulka aan si toos ah loo tijaabin.
- Jawaabta saxda ah:run
- been
