Density

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 is Density calculated?

Back

Density = Mass / Volume.

Front

What are the units of Density?

Back

The units of density are typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

What does it mean if an object floats in water?

Back

If an object floats in water, it has a lower density than water (1 g/cm³).

Front

What does it mean if an object sinks in water?

Back

If an object sinks in water, it has a higher density than water (1 g/cm³).

Front

What is the density of water?

Back

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

Front

If an object has a mass of 10g and a volume of 5cm³, what is its density?

Back

Density = 10g / 5cm³ = 2 g/cm³.

Front

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

Back

If the mass increases while the volume remains the same, the density of the object increases.

Front

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

Back

If the volume increases while the mass remains the same, the density of the object decreases.

Front

What is the principle of buoyancy?

Back

The principle of buoyancy states that an object submerged in a fluid experiences an upward force equal to the weight of the fluid displaced by the object.
