• mass - volume

• mass + volume

• mass * volume

Which property of matter does density represent?

• Size per unit weight

• Mass per unit volume

• Volume per unit mass

• Weight per unit volume

What is the SI unit for density?

• g/cm^3

• kg/m^3

• kg/L

• g/m^3

• gas

• plasma

• liquid

• solid

What is the formula for calculating the density of a liquid?

• density = volume/mass

• density = weight/volume

• density = mass/volume

• density = mass x volume

What is the formula for calculating the density of a gas?

What is the difference between a homogeneous and a heterogeneous mixture?

• A homogeneous mixture is evenly distributed and cannot be visibly distinguished, while a heterogeneous mixture is not evenly distributed and can be visibly distinguished.

• A homogeneous mixture is made up of only one substance, while a heterogeneous mixture is made up of multiple substances.

• A homogeneous mixture has a uniform composition throughout, while a heterogeneous mixture has a varying composition.

• A homogeneous mixture is a solid, while a heterogeneous mixture is a liquid.

Give an example of a homogeneous mixture.

• chocolate chip cookie

• saltwater solution

• oil and vinegar dressing

• sugarwater solution

Give an example of a heterogeneous mixture.

• Smoothie

• Salad

• Soup

• Ice cream

How can you separate the components of a heterogeneous mixture?

• By using chemical methods such as oxidation or reduction.

• By using electromagnetic methods such as radiation or magnetism.

• By using physical methods such as filtration, distillation, evaporation, or centrifugation.

• By using biological methods such as fermentation or digestion.
