Density/Density Column Review

Front

What is density?

Back

Density is the mass of an object divided by its volume. It tells us how much matter is packed into a certain space.

Front

How do you determine if an object will float or sink in water?

Back

An object will float if it is less dense than water and sink if it is more dense than water.

Front

What is the density of water?

Back

The density of water is approximately 1 gram per cubic centimeter (g/cm³).

Front

Why do ice cubes float in water?

Back

Ice cubes float because they are less dense than liquid water.

Front

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

Back

Generally, when a substance is heated, it expands and its density decreases.

Front

What is an example of a substance that is less dense than water?

Back

Oil is an example of a substance that is less dense than water.

Front

What is an example of a substance that is more dense than water?

Back

Corn syrup is an example of a substance that is more dense than water.

Front

What does it mean if an object is buoyant?

Back

If an object is buoyant, it means it can float in a fluid.

Front

What is a density column?

Back

A density column is a layered arrangement of liquids with different densities, where less dense liquids float on top of denser liquids.

Front

How does saltwater compare to freshwater in terms of density?

Back

Saltwater is denser than freshwater because the dissolved salt increases the mass of the water without significantly increasing its volume.
