What is a classification system used for?

• To measure volume

• To organize information based on observable characteristics

• To make predictions

• To calculate density

What is a derived unit?

• A unit used only for length

• A unit used only for mass

• A unit that combines multiple measurements

• A single unit of measurement

What is the most common way to calculate the volume of a regular-sided object?

• Measuring its mass

• Using water displacement

• Length times width times height

• Using a classification system

What does density measure?

• The weight of an object

• The amount of space an object occupies

• The amount of mass per unit volume

• The temperature of an object

How does temperature affect the density of a substance?

• Higher temperature increases density

• Higher temperature decreases density

• Temperature has no effect on density

• Lower temperature decreases density

What is the relationship between pressure and density?

• As pressure decreases, density increases

• Pressure has no effect on density

• As pressure increases, density increases

• As pressure increases, density decreases

What is unique about the density of water compared to most substances?

• Water is most dense in its solid phase

• Water is most dense in its gas phase

• Water's density does not change with temperature

• Water is most dense at 4°C in its liquid phase
