Density is defined as mass per unit volume.

Back

Density is a measure of how much mass is contained in a given volume.

Front

Back

This is the formula to calculate density.

Front

The SI unit of density is kilogram per cubic metre (kg/m³).

Back

This unit is used to express the density of materials.

Front

Density can also be expressed in grams per cubic centimetre (g/cm³).

Back

This is another common unit for measuring density.

Front

A less dense object floats on a denser medium.

Back

This principle explains why some objects float while others sink.

Front

A block of pine wood floats on water.

Back

A block of pine wood has a density of 0.510 g/cm³.

Water has a density of 1.00 g/cm³.

The density of pine wood is less than the density of water.

Pine wood is less dense than water.

Front

A block of iron sinks in water.

Back

A block of iron has a density of 7.87 g/cm³.

Water has a density of 1.00 g/cm³.

The density of iron is more than the density of water.

Iron is denser than water.
