Density

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) or grams per milliliter (g/mL).

Front

How do you calculate the density of an object?

Back

Density = Mass / Volume.

Front

What happens to an object with a density greater than the liquid it is placed in?

Back

It will sink.

Front

What happens to an object with a density less than the liquid it is placed in?

Back

It will float.

Front

What is the density of water?

Back

1 g/cm³ or 1 g/mL.

Front

If an object has a mass of 10 g and a volume of 2 cm³, what is its density?

Back

Density = 10 g / 2 cm³ = 5 g/cm³.

Front

What is the relationship between density and buoyancy?

Back

An object will float if it is less dense than the fluid it is in, and sink if it is more dense.

Front

Which is denser: gold (19.3 g/cm³) or aluminum (2.7 g/cm³)?

Back

Gold is denser than aluminum.

Front

What is the formula to find the volume of an object if you know its mass and density?

Back

Volume = Mass / Density.

Front

If a liquid has a density of 0.8 g/mL, will it float or sink in water?

Back

It will float because it is less dense than water.
