Density

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated by dividing mass by volume.

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What units are used to measure density?

Back

Common units for density include grams per cubic centimeter (g/cm³) for solids and grams per milliliter (g/ml) for liquids.

Front

If an object has a mass of 10g and a volume of 5cm³, what is its density?

Back

Density = 10g / 5cm³ = 2 g/cm³.

Front

What happens to the density of an object if its mass increases while its volume remains the same?

Back

The density increases.

Front

What happens to the density of an object if its volume increases while its mass remains the same?

Back

The density decreases.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³.

Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which is determined by the density of the object compared to the density of the fluid.

Front

If an object is less dense than the fluid it is in, what will happen?

Back

The object will float.

Front

If an object is more dense than the fluid it is in, what will happen?

Back

The object will sink.
