Exam-style question
Try this first
Which of the following is an assumption made in the ideal gas model? Scenario focus: use simple harmonic motion in a distinct A-Level Physics context and identify the relevant physical quantity before choosing the answer.
- A.Gas particles have significant volume.
- B.Gas particles do not attract or repel each other.
- C.Gas particles are stationary.
- D.Gas particles collide inelastically.
Model answer
What a good answer should say
- Gas particles do not attract or repel each other.
Explanation
Why this works
The correct answer is Gas particles do not attract or repel each other.. This option is correct for Thermal physics because it applies the simple harmonic motion idea in the stem and keeps the relevant quantity, unit, and physical conclusion together.
The alternatives either use a neighbouring formula, omit a required variable, or describe a different physical situation.
