Changes of state and the particle model
Question
- A. It involves a change in chemical composition
- B. It is a reversible change
- C. It results in a permanent change
- D. It only occurs at high pressures
Answer
The correct answer is It is a reversible change.
Explanation
Definition lens: Give the precise definition, then add a context sentence that shows how it is used. This question asks: Which statement is true regarding the physical change of condensing. The correct response is It is a reversible change, because changes of state are explained by particle energy and arrangement. In Changes of state, the marking point should connect directly to explain condensing using decreased particle energy and closer particle arrangement. If the question includes values, the working must keep the appropriate unit and operation; if it is an explanation, it must name the relevant particle behaviour or energy change. This item belongs to Changes of state and the particle model, so avoid answers that switch to a different quantity, confuse heat with temperature, or describe gas pressure without collisions when collisions are the reason. Checkpoint 150 is distinct because it uses this exact question context and the definition lens rather than a generic particle-model sentence.
Common mistake
Confusing Condensation with Other Changes
Students often confuse condensing with freezing, thinking both processes involve a solid forming from a liquid.
Clarify that condensing involves a gas turning into a liquid due to decreased particle energy, while freezing is the process of a liquid becoming a solid.
