Quest | Answer |
---|---|
What is the 1 particle theory? | 1 all matter is made up of tiny particles |
What is the 2 particle theory? | 2 particles have empty spaces between them |
What is the 3 particle theory? | 3 even though you cannot see them, particles are moving randomly all the time |
What is the 4 particle theory? | 4 particles move faster and spread farther apart when they are heated. |
What is the 5 particle theory? | 5 particles attract each other/ so they tend to stay together rather than fly apart. |
What are the three states of matter? | Solid, liquid, and gas. |
What is a thing where all three come in? | A snow flake liquid (water), gas (the water dissolving), solid (ice). |
Define a solid. | A solid has a definite shape and volume. Also it's particles are close together and in rows. |
Define liquid. | A liquid has a definite volume but not shape. Also it's particles are close together but going in different directions. |
Define gas. | Gas has no definite shape nor volume.Also it's particles are far apart and going in different directions. |
What makes a pure substance? | A mixture that is only made from 1 particle. |

What is some pure substances? | Distilled water, table salt, and aluminum foil. |
What is some mixtures? | Tap water, cows milk, and juice. |

What is an example of a dangerous pure substances? | Mercury and lead. |
What is the difference between a mechanical mixture and a solution? | Mechanical mixture is one where you can see the different parts. A solution looks like a pure substance and has more than one kind of particle. |
What 2 categories do scientist classify mixtures? | Mechanical mixtures and solutions. |

What is a Mechanical mixture that you can see? | Sand, soil, gravel, twigs, and leaves. |
What is a Mechanical mixture that you can't see? | Sugar, and salt because they look alike. |
what is the definition for a solution? | The definition for a solution is a mixture that looks like a single pure substance; a uniform mixture of two or more pure substances. |
what is the definition for a solution? | The definition for a solution is a mixture that looks like a single pure substance; a uniform mixture of two or more pure substances. |
What is some solution examples? | Steel, |

What is some solution examples? | Steel, Sea water, milk, and air. |
Can solutions be in any of the three states? | Yes. |
Why can you not see the different parts of a solution? | Because the different particles of a solution are mixed evenly. |
What is the chart shows for classifying matter? | Matter can be combine to form pure substances or mixtures. Then mixtures can be either a solution, or a mechanical mixture. |
What are solutions and what are they made of? | A solutions is a mix of two or more kinds of particles in a mixture. It is made of solute and solvent. |
Dose the two kinds of particles stay whole? | Yes they do. |
Dose one of the particles dissolve into the other? | Yes they do. |
Is their less solvent in the solution then the solute? | No their is not. |
What is the definition for dissolve? | The definition for dissolve is to mix one type of matter into another type of matter to form a solution. |
What is the definition for solute? | The definition for solute is the smaller part of a solution; the part of a solution that dissolves in to the solvent. Solute is always the mixture powder. |
What is the definition for solvent? | The definition for solvent is the larger part of a solution; the part of a solution that dissolves in the solvent. |
What is the definition for dissolving? | The definition for dissolving is mixing completely with a solvent to form a solution. |
What is some examples of some solvents? | Turpentine, ethanol ( in perfume), and ethyl acetate ( in nail polish ). |
Should you say that the solute dose not dissolve? | No it is still their. |
What are some examples when the solute and the solvent is with the three states of matter? | |
Why is water sean as the universal solvent? | Because it dissolves more substances than any other solvent. |
What is a soluble? | A soluble is a solute that is able to dissolve into a certain solvent is called soluble. |
When is the solute soluble? | When the solute particles are attracted to the solvent. |
What is an example of soluble? | when Sugar is in water. |
What is insoluble? | insoluble is when a solute that is not able to dissolve into a certain solvent means insoluble. |
When the solute is insoluble what is happening? | When the solute particles are not attracted to the solvent particle, the solute is insoluble. |
What makes a solution? | Solute and solvent makes a solution. |
What are concentration and solubility. | Concentration is the amount of solute present in an amount of solution. Then solubility is a measure of how much solute can dissolve in a certain solvent to form a saturated solution at a particular temperature and volume. |
What dose concentration and dilute mean together? | It means how much solute is in a solution. |
What is a concentration solution mean? | It means a solution with a large amount of solute is a concentration solution. |
