Question

b. other descriptions, such as mass or volume, are 3. particle ____ and particle ____ determine a substance’s state of matter.

Explanation:

To solve this fill - in - the - blank question related to the states of matter (a topic in Chemistry, which is a subfield of Natural Science), we analyze the key concepts:

For the first blank (after "Particle"):

In the context of determining the state of matter, the arrangement of particles is a crucial factor. For example, in a solid, particles are closely packed in an orderly arrangement; in a liquid, they are close but can move past each other; and in a gas, they are far apart and move freely. So the first blank should be "arrangement".

For the second blank (after "and particle"):

The movement of particles also determines the state of matter. Solids have particles that vibrate in place, liquids have particles that can slide past one another, and gases have particles that move freely and rapidly. So the second blank should be "movement" (or "motion").

For the blank in part b (after "are"):

Mass and volume are examples of physical properties of a substance. These properties do not involve a change in the chemical identity of the substance and are used to describe and identify substances. So the blank in part b should be "physical properties".

Final Answers:

• 3. Particle \(\boldsymbol{\text{arrangement}}\) and particle \(\boldsymbol{\text{movement}}\) determine a substance's state of matter.
• b. Other descriptions, such as mass or volume, are \(\boldsymbol{\text{physical properties}}\).
