Density

Front

What is density?

Back

Density is the mass of an object divided by its volume. It is a measure of how much matter is packed into a given space.

Front

How do you calculate density?

Back

Density = Mass / Volume

Front

What units are used to measure density?

Back

Common units for density include grams per cubic centimeter (g/cm³) and kilograms per cubic meter (kg/m³).

Front

Why is density important in identifying substances?

Back

Density helps to distinguish between different substances, as each substance has a unique density.

Front

What happens to the density of an object if its mass increases while its volume remains the same?

Back

The density increases.

Front

What happens to the density of an object if its volume increases while its mass remains the same?

Back

The density decreases.

Front

Which is denser: a kilogram of feathers or a kilogram of lead?

Back

They have the same mass, but lead is much denser than feathers.

Front

What is the relationship between density and buoyancy?

Back

An object will float in a fluid if it is less dense than the fluid.

Front

If an object has a density of 1 g/cm³, what will happen if it is placed in water?

Back

It will neither sink nor float; it will be suspended in the water.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³ at 4°C.
