Classify the following pieces of matter:
bronze
pure water
tap water
trail mix

bronze - solid

pure water - liquid

tap water - liquid

trail mix - solid

Explanation:

There are 4 classes of matter based on the characteristics of their molecules:

The molecules in solids are tightly packed together and are more or less fixed about a point with very little of no movement. The molecules in liquids are less tightly packed and are able to take the shape of their containers. The molecules in gases are loosely packed and compressible. They can take the shape of containers as well as expand to a container due to their loosely packed molecules.

Plasma molecules neither have shape nor volume but are able to produce both magnetic and electric currents as well as respond to electromagnetic fields.

Hence bronze has all the characteristics of a solid, pure and tap water both have the characteristics of a liquid, while trail mix can be considered a solid.
