What is Density?

• Density is when a property of matter that measures how close together the liquids are inside a substance. This can determine things like if something will float or sink.

• Density is when a property of matter that measures how close together the gases are inside a substance. This can determine things like if something will float or sink.

• Density is when a property of matter that measures how close together the particles are inside a substance. This can determine things like if something will float or sink.
