What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in grams per cubic centimeter (g/cm³).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What happens to an object with a density less than 1 when placed in water?

Back

It will float.

Front

What happens to an object with a density greater than 1 when placed in water?

Back

It will sink.

Front

What is a physical property?

Back

A characteristic of a substance that can be observed without changing its identity, such as color, density, or melting point.

Front

What is a chemical property?

Back

A characteristic that describes a substance's ability to undergo a specific chemical change, resulting in a new substance.

Front

If two substances have the same volume but different masses, what can be said about their densities?

Back

The substance with the greater mass has a higher density.

Front

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

Back

Density is directly proportional to mass and inversely proportional to volume.

Front

What is the density of a substance with a mass of 60 grams and a volume of 15 cm³?

Back

Density = 60 g / 15 cm³ = 4 g/cm³.

Front

How can density be used to identify substances?

Back

Different substances have unique densities; comparing the density of an unknown substance to known values can help identify it.
