QuestAnswer
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 makes a substance a mixture? A mixture is made of two or more pure substances mixed together.
What is some pure substances? Distilled water, table salt, and aluminum foil.
What is some mixtures? Tap water, cows milk, and juice.
What is the definition for pure substances? A pure substance is matter that contains only one kind of particle.
What is the definition for a mixture? A mixture is matter that contains two or more pure substances mixed together.
What is the particle theory formula? It is pure substance + pure substance = a mixture.
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 the definition for Mechanical mixtures? The definition for Mechanical mixtures is a mixture with different parts that you can see.

What 2 categories do scientist classify mixtures? Mechanical mixtures and solutions.
what is the definition for Mechanical mixtures? The definition for Mechanical mixtures is a mixture with different parts that you can see.
What is a Mechanical mixture that you can see? Sand, soil, gravel, twigs, and leaves.

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 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, 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.
What dose dilute solution mean? It means a solution with a small amount of solute is a dilute solution.
What is the definition for dilute solution? The definition for dilute solution is a solution with a large number of solute particles in a given volume of solution.
What is the definition for concentration solution? The definition for concentration solution is a solution with a small number of solute particles in a given volume of solution.
