Density Triangle Flashcard

Front

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 the volume of an object?

Back

Volume can be calculated using the formula: Volume = Mass / Density.

Front

What is the formula for density?

Back

Density = Mass / Volume.

Front

If an object has a mass of 150 grams and a density of 11.3 g/cm³, what is its volume?

Back

Volume = 150 g / 11.3 g/cm³ = 13.3 cm³.

Front

What is the mass of an object with a volume of 24 cm³ and a density of 3 g/cm³?

Back

Mass = Density x Volume = 3 g/cm³ x 24 cm³ = 72 g.

Front

What is the density of an object with a mass of 9.65 grams and a volume of 0.5 cm³?

Back

Density = Mass / Volume = 9.65 g / 0.5 cm³ = 19.3 g/cm³.

Front

If a rock has a mass of 14 grams and a volume of 2 cm³, what is its density?

Back

Density = Mass / Volume = 14 g / 2 cm³ = 7 g/cm³.

Front

What is the density of an eraser with a mass of 4 grams and a volume of 2 cm³?

Back

Density = Mass / Volume = 4 g / 2 cm³ = 2 g/cm³.

Front

How does density relate to buoyancy?

Back

Objects with a density less than the fluid they are in will float, while those with a greater density will sink.

Front

What is the significance of density in identifying materials?

Back

Density can help identify substances, as different materials have unique density values.
