Grade 8 Mix & Flow of Matter 2.0

Concentration Concentration

100

When discussing the amount of solute dissolved in a solvent, you use this term (can be high or low)

Concentration

200

If there is only a small amount of solute dissolved in the solvent, it is called this kind of solution 

diluted

300

12g salt per 200ml apple juice would have a concentration of this

12/200 divided by 2 = 6/100 = 0.06 = 6%

400

650g of iced tea per 1L coffee

(1L=1,000ml)

650/1,000 divided by 10 = 65/100 = 0.65 = 65%

500

If the exact amount of solute has been added to a solvent where no more can be dissolved, it is called this 

Saturated 

Solubility

100

The substance that gets dissolved is called this, the substance that does the dissolving is called this

Solute, Solvent

200

For solids, when temperature increases solubility does this

Increases

300

For gasses, when temperature increases solubility does this

Decreases

400

Solubility depends on these 3 factors

Type of solute, type of solvent, temperature 

500

When warm water from factories are released back into lakes, it has this kind of effect on the environment

Thermal Pollution 

particle theory

100

All matter is made up of this

Tiny particles

200

What are the four states of matter

Solid, Liquid, Gas, Plasma

300

True or False, particles are always attracted to each other

False! Only sometimes. Think of oil and water

400

True or False. Particles in solids do not have spaces between them

False! All particles have spaces between them

500

Two ways to make a solute dissolve in a solvent FASTER is ....

Increase the temperature. Agitate/stir the solution. Increase the surface area (individual particles instead of stick together)

Solvent this Question

100

If you can see the different elements in a mixture, it is called this

Heterogenous mixture

200

If you can not see the different elements in a mixture, it is called this

Homogenous mixture

300

All mixtures are homogeneous except this one

Mechanical Mixture

400

If water is the solvent, it is called this kind of solution

aqueous solution

500

This technique tests to see whether a substance is pure

Paper Chromatography 

Name That Mixture

100

If a substance is not classified as a mixture, it is this instead

Pure Substance

200

Italian Salad dressing is an example of this kind of mixture

Mechanical Mixture

300

Dust in air is an example of this kind of mixture

Suspension 

400

Marshmallows are an example of this kind of mixture

Colloid 

500

In our Lab we dissolved sugar in water. It became this type of mixture
