Answer 3

group together based on similar traits

Question 4

physical state

Answer 4

the classification of matter as a solid, liquid, or gas

Question 10

density

Answer 10

a measurement that describes how mass is packed into volume
An object that sinks displaces an amount of fluid equal to the object’s volume.

When we compare the densities of different materials or objects, this is called relative density.
For example iron is more dense than water. If something is more dense, it will sink. If something is
less dense, it will float.
