Modeling Matter

What is the difference between a compound and a mixture?

• A compound is a mixture of two or more elements that are not chemically bonded.

• A compound is a substance formed when two or more elements are chemically bonded, while a mixture is a combination of two or more substances that are not chemically bonded.

• A compound is a type of mixture that can be separated by physical means.

• A mixture is a substance formed when two or more elements are chemically bonded.

What is a molecule?

• A molecule is a single atom.

• A molecule is two or more atoms bonded together.

• A molecule is a type of chemical reaction.

• A molecule is a large structure made of cells.

What is a solute?

• A substance that is dissolved in a solvent.

• A liquid that dissolves a solute.

• A mixture of two or more substances.

• A solid that cannot dissolve in any liquid.

What is all matter made of?

• Molecules

• Atoms

• Cells

• Particles

What is condensation?

• The process by which vapor turns back into liquid.

• The process of liquid turning into vapor.

• The process of solid turning into liquid.

• The process of gas turning into plasma.

What is an atom?

• A molecule made of two or more atoms.

• The smallest unit of an element that retains the properties of that element.

• A type of chemical bond between atoms.

• A large particle that makes up matter.

What are the three states of matter?

• Solid, liquid, and gas.

• Solid, liquid, and plasma.

• Solid, gas, and vapor.

• Liquid, gas, and steam.

What is solubility?

• The ability of a substance to dissolve in a solvent.

• The measure of how much solute can be added to a solution before it becomes saturated.

• The process of separating a mixture into its individual components.

• The temperature at which a substance changes from solid to liquid.

What does it mean to dissolve a substance in a liquid?

• To mix evenly into a liquid by breaking apart into pieces that are too small to see.

• To create a solid mass in the liquid.

• To separate the substance into larger pieces that float on the surface.

• To change the color of the liquid without mixing it.

What happens to solubility when you stir a solution?

• Stirring the solution decreases the solubility.

• Stirring the solution has no effect on solubility.

• Stirring the solution increases the solubility.

• Stirring the solution makes it less concentrated.
