What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula: Density = Mass/Volume.

Front

What are the two types of measurements that make up density?

Back

Mass and Volume.

Front

How do you measure mass in a laboratory?

Back

Using a triple beam balance.

Front

True or False: The density of a specific type of material never changes.

Back

True.

Front

Why do ice cubes float in water?

Back

Because the water is more dense than the ice cubes.

Front

What is the unit of density in the metric system?

Back

Grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

If an object has a density greater than 1 g/cm³, will it sink or float in water?

Back

It will sink.

Front

What happens to the density of a substance when it is heated?

Back

Generally, the density decreases as the substance expands.

Front

What is the relationship between mass, volume, and density?

Back

Density is the ratio of mass to volume; if mass increases while volume remains constant, density increases.

Front

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

Back

By using the water displacement method to measure the volume and then dividing the mass by that volume.
