Lesson 2:Density
![Page 2: Lesson 2: Density. Density is a property of matter that shows a relationship between mass and volume. It measures the amount of matter in a certain space.](https://reader031.fdocuments.in/reader031/viewer/2022032105/56649f565503460f94c7a6ff/html5/thumbnails/2.jpg)
Density is a property of matter that shows a relationship
between mass and volume.
It measures the amount of
matter in a certain space.

An object or substance with a low density will have less mass than a more dense object with the same
volume.

An object’s density can be calculated if we know it’s
mass and volume.
Density is measured using the unit grams per cubic
centimeter (g/cc).

To calculate density, we divide the object’s mass by the object’s volume

A golf ball has a mass of 45 grams and a volume of
40 cubic centimeters
Density = Mass ÷ VolumeDensity = 45 ÷ 40
Density = 1.13 g/cc

Water has a density of 1 g/cc.
An object with a density less than
1 g/cc will float, but an object with a
density more than 1 g/cc will sink.

Buoyancy is the ability of an object to float in water.

Key Questions:1) What does density measure? How is it related to mass and volume?2) How can we measure the density of an object?3) What makes an object buoyant in water? How does this relate to the object’s density?
