How bonding and structure are related to the properties of substances
Question
- A. Particles move closer together and become fixed in place
- B. Particles move further apart and become more mobile
- C. Particles remain unchanged
- D. Particles gain kinetic energy
Answer
The correct option is Particles move closer together and become fixed in place. This answer is correct because it matches the approved learning objective to explain melting, boiling, freezing and condensing using particle theory in the subtopic The three states of matter.
Explanation
The correct option is Particles move closer together and become fixed in place. Particles move closer together and become fixed in place is correct because it directly supports the approved learning objective to explain melting, boiling, freezing and condensing using particle theory. This belongs to the subtopic The three states of matter within How bonding and structure are related to the properties of substances, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from The three states of matter.
Common mistake
Confusing Melting and Boiling Points
Students often confuse melting points with boiling points, thinking they are the same.
Remember that melting point is the temperature at which a solid turns into a liquid, while boiling point is the temperature at which a liquid turns into a gas.
