Front

What is density?

Back

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

Front

What happens to an object that is less dense than the liquid it is in?

Back

It floats.

Front

What happens to an object that is denser than the liquid it is in?

Back

It sinks.

Front

Which liquid is the least dense?

Back

Oil.

Front

True or False: The density of a specific type of material never changes.

Back

True.

Front

Why do some substances float on water?

Back

They are less dense than water.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid.

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

What is a common unit of measurement for density?

Back

Grams per cubic centimeter (g/cm³).
