25/26 Unit 2 Properties of Matter

Matter

• Anything that has mass and takes up space.

• A substance that can be seen but not touched.

• A form of energy that cannot be measured.

• A type of chemical reaction that occurs in solids.

Buoyancy

• The ability or tendency of an object to float in a fluid.

• The force that pulls objects downwards in a fluid.

• The measure of how heavy an object is in water.

• The resistance of an object to being submerged in a fluid.

Electricity

• The set of physical phenomena associated with the presence and motion of electric charge.

• A type of energy that can be created from solar panels.

• A method of storing energy in batteries.

• The flow of water through a turbine to generate power.

Chemical Property

• A characteristic of a substance that is observed during a reaction in which the chemical composition or identity of the substance is changed.

• A property that can be observed without changing the substance's identity.

• A measurement of the amount of substance present in a sample.

• A characteristic that describes how a substance interacts with light.

Conductor

• A material that allows the flow of electrical current.

• A substance that resists the flow of electrical current.

• A device that stores electrical energy.

• A type of electrical circuit that does not allow current to flow.

Volume

• The amount of space an object or substance occupies.

• The weight of an object.

• The color of an object.

• The temperature of an object.

Element

• A substance that cannot be broken down into simpler substances by chemical means.

• A mixture of two or more substances.

• A compound formed by chemical reactions.

• A solution that can be separated by physical means.

Physical Change

• A change in a substance that does not involve a change in the identity of the substance.

• A change that alters the chemical composition of a substance.

• A process that results in the formation of a new substance.

• A change that occurs only at high temperatures.

Solubility

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

• The measure of how much solute can be dissolved in a given amount of solvent at a specific temperature.

• The process of separating a mixture into its components.

• The ability of a substance to conduct electricity when dissolved in water.

Solute

• The substance that is dissolved in a solution.

• A liquid that dissolves a solute.

• A mixture of two or more substances.

• The process of dissolving a substance.
