Final answer:
The arrangement 'Packed tightly together' corresponds to solids where particles are closely held together. 'Close, but free to flow' corresponds to liquids where particles are closely arranged but can move over each other. 'Spaced relatively far apart' corresponds to gases, where particles are free to move in available space.
Step-by-step explanation:
Inadressing the question, which requires matching each arrangement of particles in matter with their respective physical state i.e., gas, liquid, solid for a. Packed tightly together, b. Close, but free to flow, and c. Spaced relatively far apart, we can correlate as follows:
a. Packed tightly together - This corresponds to the state of a solid, where atoms or molecules are in a rigid arrangement and held closely together. An example of this is a rock, where all its molecules are held in place by respective intermolecular forces, giving it a specific shape.
b. Close, but free to flow - This corresponds to the state of a liquid. In a liquid, particles are close to each other but can slide past one another, for instance, water. Due to the arrangement and mobility of its molecules, water can flow and conform to the shape of its container.
c. Spaced relatively far apart - This corresponds to the state of a gas. In a gas, particles are not as close and can move freely in all directions, which is why gases take both the shape and volume of the container unless contained.
