Density

Front

What is density?

Back

Density is a measure of mass per unit volume, typically expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

How do you calculate density?

Back

Density is calculated using the formula: Density = Mass / Volume.

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 50g and a volume of 25cm³, what is its density?

Back

Density = 50g / 25cm³ = 2g/cm³.

Front

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

Back

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

Front

What is the relationship between density and buoyancy?

Back

An object will float in a fluid if its density is less than the density of the fluid.

Front

How does temperature affect the density of liquids?

Back

Generally, as temperature increases, the density of liquids decreases because they expand.

What is the formula for calculating the volume of a rectangular prism?

Back

Volume = Length × Width × Height.

Front

If a substance has a density of 8g/cm³, what would be its mass if its volume is 4cm³?

Back

Mass = Density × Volume = 8g/cm³ × 4cm³ = 32g.

What is the density of copper?

Back

The density of copper is approximately 8.96 g/cm³.
