Understanding Material Density

What is the definition of density?

• Density is mass per unit volume.

• Density is the volume of an object divided by its mass.

• Density is the weight of an object.

• Density is the temperature of a substance.

What is the formula for calculating density?

• Density = Mass - Volume

• Density = Volume / Mass

• Density = Mass + Volume

• Density = Mass / Volume

What are the common units of mass used in science?

• meters

• grams, kilograms, metric tons

• pounds

• liters

How do you calculate the density of an object?

• Density = Mass - Volume

• Density = Mass / Volume

• Density = Mass + Volume

• Density = Volume / Mass

What is the density of water in grams per cubic centimeter?

• 0.5 g/cm³

• 1 g/cm³

• 1.5 g/cm³

• 2 g/cm³

How does temperature affect the density of liquids?

• Temperature has no effect on the density of liquids.

• As temperature increases, density increases as well.

• Density remains constant regardless of temperature changes.

• Temperature inversely affects the density of liquids; as temperature increases, density decreases, and vice versa.

What is the typical density range for solids?

• 5 g/cm³ to 10 g/cm³

• 15 g/cm³ to 25 g/cm³

• 0.1 g/cm³ to 1 g/cm³

• 1 g/cm³ to over 20 g/cm³

If an object has a mass of 50 grams and a volume of 10 cm³, what is its density?

• 10 g/cm³

• 0.5 g/cm³

• 2 g/cm³

• 5 g/cm³

What is the density of air at sea level?

• 0.8 kg/m³

• 2.0 kg/m³

• 1.225 kg/m³

• 1.5 kg/m³

How can you determine the density of an irregularly shaped solid?

• Volume = Length x Width x Height

• Density is determined by the shape of the object

• Density = Mass + Volume

• Density = Mass / Volume, where Volume is determined by water displacement.
