Classification of Matter Review quizs

Boyle's law

• A law that states pressure and volume are directly proportional.

• A law that describes the relationship between temperature and pressure.

• A law that describes the relationship between volume and pressure - as volume increases, pressure decreases. Inversely proportional.

• A law that states that the volume of a gas is constant regardless of pressure.

How can you identify a heterogeneous mixture?

• By the presence of visibly different substances or phases within the mixture.

• By its uniform composition throughout the mixture.

• By its ability to settle into layers over time.

• By its consistent color and texture.

Identify as physical or chemical property: liquid to gas

• chemical property

• physical property

• biological property

• nuclear property

What is the definition of a pure substance?

• A pure substance is a material that has a constant composition and consistent properties throughout.

• A pure substance is a mixture of two or more elements.

• A pure substance is a material that can change its properties under different conditions.

• A pure substance is a compound that contains at least two different elements.

What is an example of a physical change?

• Melting ice

• Burning wood

• Rusting iron

• Dissolving sugar in water

Charles's Law

• A law that states volume and temperature are inversely proportional to each other.

• A law that describes the relationship between volume and temperature as directly proportional to each other. As volume increases, temperature decreases.

• A law that states that pressure and volume are directly proportional to each other.

• A law that describes the relationship between pressure and temperature as inversely proportional to each other.

What is a heterogeneous mixture?

• A mixture where components are uniformly distributed.

• A mixture in which the components are not uniformly distributed, and different parts of the mixture can be seen and separated.

• A mixture that consists of only one type of substance.

• A mixture that cannot be separated into its individual components.

Law of conservation of mass states...

• Mass can be created or destroyed in a chemical reaction.

• Mass is not created nor destroyed. The reactants in a chemical reaction must equal the products.

• The total mass of reactants is always less than the total mass of products.

• Mass is only conserved in physical changes, not chemical changes.

What is the classification of brass?

• A heterogeneous mixture

• A compound

• A homogeneous mixture

• An element

What is matter?

• Anything with mass and volume

• A substance that can be seen and touched

• A form of energy

• A concept in physics that describes force
