Density

Front

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 is the formula to calculate density?

Back

Density = Mass / Volume.

Front

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

Back

It will float.

Front

What is the density of water?

Back

The density of water is approximately 1 g/mL.

Front

How do you calculate the density of an object?

Back

To calculate density, divide the mass of the object by its volume.

Front

What units are commonly used to express density?

Back

Common units for density include g/mL, g/cm³, and kg/m³.

Front

If a rock has a mass of 20g and a volume of 4cm³, what is its density?

Back

Density = 20g / 4cm³ = 5 g/cm³.

Front

What happens to an object with a density greater than that of water when placed in water?

Back

It will sink.

Front

What two measurements are needed to determine density?

Back

Mass and Volume.

Front

What is the relationship between density and buoyancy?

Back

An object will float if its density is less than the density of the fluid it is in; it will sink if its density is greater.
