Density
Definition of Density
The density of an object tells you how much matter is in the object, compared to its volume.
The density of water is about \(1 \text{kg/L}\). So, \(1 L\) of water has a mass of \(1 \text{ kg}\). The density of apple juice is about the same. This is really handy to know when you're deciding how much apple juice you can carry when you're walking home from the supermarket.
Anything that is more dense than water will sink if it's placed in water, and anything less dense than water will float in water.
In the picture, the rock sank when it was placed in the bowl of water because it is more dense than the water. The ball floated because it is less dense than the water.
