| Question | Answer |
|---|---|
| What is matter? | Anything that takes up space and has mass. |
| What are properties of matter? | They describe the characteristics of matter. |
| What are some properties you can use to describe matter? | colour, odour,taste, feel, density, boiling point, freezing point, state |
| What are some properties of water? | colourless, tasteless, can be a solid, liquid or gas, boils at 100 degrees and freexes at 0degrees. |
| Homogeneous matter | 1 set of properties - it looks the same throughout. |
| Heterogeneous matter | more than one set of properties - you can see the different parts in it. |
| pure substance | All of the particles look the same. It cannot be separated into different substances. |
| Mechanical Mixture | Same as heterogeneous matter. You can see the different parts that were added together. |
| Homogeneous Mixture | A mixture that has only 1 set of properties. It all looks like one thing. The same as a solution. |
| Solution | A homogeneous mixture. It's mixted together so well you can only see one set of properties. |
| What are the two parts of any solution? | Solute and Solvent |
| Solute | gets dissolved to form a solution - the part with the least amount |
| Solvent | does the dissolving the form a solution - the part in the greater amount. |
| dissolving | making a solution by mixing two or more substances. |
| What determines if something will dissolve? | The attraction between the solute and solvent particles. |
| Concentration | The amount of solute dissolved in the solvent - measured in grams per litre g/L |
| Concentrated | Lots of solute dissolved in the solvent. |
| Dilute | Relatively little solute dissolved in the solvent. |
| Unsaturated solution | more solute can dissolve because there are free solvent particles |
| Saturated | no more solute will dissolve at the same temperature because all of the solvent particles are full |
| Hydrometer | Measures the concentration of solutions. |
| How does a hydrometer work? | It floats higher in concentrated solutions and lower in dilute solutions. |
| Is the Dead Sea concentrated or dilute? | So concentrated that you can't sink. |
| What four things can affect the rate of dissolving? | Stirring, Crushing, Temperature and Pressure |
| Will a hydrometer float high or low in a dilute solution? | low |
| What are the three states of matter? | Solid, liquid and gas |
| Why won't a rock dissolve in water? | Because its particles are not attracted to the water particles. |
| Soluble | means it will dissolve |
| Insoluble | means it won't disslove |
| In evaporation, what do we get back from the mixture...the solute or the solvent | the solute |
| In distillation, what do we get back from the mixture...the solute or the solvent | the solvent |
| How would you distill water and purify it | boil and evaporate the water, collect the steam, cool it until it condenses back into a liquid |
