Relative density describes
- the amount of space an object takes up.
- the amount of matter in an object.
- how dense something is compared with a reference material.
- anything that has mass and takes up space.

Water has a density of 1.0 g/mL. An object with a density of 1.4 g/mL is placed into the water. Which statement describes what happens when the object is placed in the water?
- The object sinks because it is denser.
- The object sinks because it is less dense.
- The object floats because it is denser.
- The object floats because it is less dense.
- The object sinks because it is denser.
