Matter and Mixtures - Review

A student observed three pieces of matter. She recorded her observations below.

Sample 1 -- The mass is 3 grams. The volume is 8 ml. It changed shape when put into a different container, but the volume remained the same.

Sample 2 -- The mass is 5 grams. The volume is 15 ml. Did not change shape in a different container.

Sample 3 -- The volume is 4 ml. Colorless. It changed shape when I changed containers. Did not fill container completely.

Sample 4 --The mass is 2 grams. The volume is 2 ml. The volume changed when put into a different container.

WHICH SAMPLE IS MOST LIKELY A GAS?

• Sample 1

• Sample 2

• Sample 3

• Sample 4

Students in class are investigating the properties of solids, liquids, and gases. The students transfer different materials from one container into another and observe what happens to the materials in the new container. Based on this investigation, how would they know if a material is a solid?

• They have a fixed shape and volume.
  

• They change shape and expand to fill different containers.
  

• They take the shape of the container, but has a fixed volume.

• They have a fixed shape, but expand to fill different containers.

Iron is magnetic. Sulfur is not. The picture shows when a magnet is placed into a mixture of sulfur and iron. What can you conclude about mixtures based on this investigation?

• The magnetic property of iron does not change when it is mixed.

• The magnetic property of sulfur changes when mixed with iron.

• The properties of matter change when different types of matter are mixed.

• The mass of matter does not change when mixed with other matter.

When I pour 3 g of salt into a beaker of 10 g water, the mass is 13 g, the water is clear, and I can't see the salt any longer. Why can't I see the salt?

• In a solution the substances cannot be distinguished as separate substances.

• In a solution the properties of a substance do not change.

• In a mixture the substances cannot be separated based on their properties.

I pour milk into my bowl of cereal in the morning. What am I making?

• A solution because there is a liquid.

• A mixture because the substances can be separated.

• A mixture because the properties change.

When two substances are mixed together, their total mass _____________________.

• changes

• does not change

I made a wicked Halloween stew using several materials! I used 15 g of frog eyes, 20 g of lizard tails, 10 g bat wings, and wizard blood. The mass of my Halloween stew was 85 g. What was the mass of the wizard blood in my mixture?

• 4 g

• 35 g

• 40 g

• 85 g

I have a of water that has a mass of 30 g. I pour in 5 g of Koolaid. My Koolaid drink mixture has a mass of 35 g.

What does this prove?

• Solids melt when combined with liquids in a mixture.

• Mixtures can be separated back into their different substances.

• The mass of the mixture is the same as the combined mass of each of its ingredients.
