Density*: the amount of matter in a given space, or volume.

A golf ball and a ping pong ball have similar volumes, but a golf ball has more mass than a ping pong ball does so the golf ball has more density.
Density is a physical property.

Answer:0.4g/cm
It will float because it is less dense than water

Physical Change*: a change that affects one or more physical properties of a substance.

Examples of physical change: Freezing water to ice
Ice is still water Sanding a piece of wood
Saw dust is still wood Dissolving sugar in water
When water is evaporated, the sugar remains

Physical changes do not change the identity of the matter involved. A stick of butter can be melted and poured on popcorn and still be called butter. Although the shape has changed, butter is still butter.
