Matter Part 2 Vocab

Saturation

• The point where no more substance will dissolve.

• The maximum temperature a liquid can reach.

• The minimum pressure required for a gas to condense.

• The concentration of a solution at its boiling point.

Chemical Change

• Occurs when one or more substances are changed into a new substance with different properties.

• A process where substances retain their original properties.

• A reaction that only involves physical changes without altering the chemical composition.

• A method of separating mixtures into their individual components.

Solvent

• A substance that does the dissolving in a solution.

• A substance that is dissolved in a solution.

• A mixture of two or more substances.

• A solid that forms from a solution.

Expand

• Molecules move closer together when heat is added, decreasing the size of an object.

• Molecules move farther apart when heat is added, increasing the size of an object.

• Molecules remain the same distance apart regardless of temperature changes.

• Molecules move randomly without any effect from heat.

Solute

• A substance that is dissolved into another substance to form a solution.

• A substance that is added to increase the boiling point of a solution.

• A substance that remains unchanged during a chemical reaction.

• A substance that is used to dilute a solution.

Extensive Property

• Changes if the amount of matter changes.

• Is independent of the amount of matter present.

• Is the same for all substances regardless of quantity.

• Is a property that cannot be measured.

Condensation

• The change of state from a solid to a liquid.

• The change of state from a gas to a liquid.

• The change of state from a liquid to a gas.

• The change of state from a gas to a solid.

Vaporization

• The process where a liquid or solid substance changes into a gas or vapor.

• The process of cooling a gas into a liquid.

• The process of mixing two liquids together.

• The process of solidifying a liquid into a solid.

Contract

• Molecules move closer together when heat is removed, decreasing the size of an object.

• Molecules move farther apart when heat is added, increasing the size of an object.

• Molecules remain unchanged regardless of temperature changes.

• Molecules vibrate more rapidly when heat is removed, increasing the size of an object.

Solution

• A mixture of gases in the atmosphere.

• A group of molecules that are mixed up in even distributions; includes solute and solvent.

• A solid substance that dissolves in a liquid.

• A chemical reaction that produces heat.
