Exam-style question
Try this first
A student makes a mistake while revising Distinguish Heat Supplied Work Done And Internal Energy. Which correction is most accurate?.
- A.A. The correction is to keep distinguish heat supplied, work done and internal energy change separate from the common neighbouring idea in Thermodynamics and engines, then explain the tested distinction.
- B.B. The mistake is harmless because the two ideas always mean the same thing.
- C.C. The correction is to memorise the wording without explaining the distinction.
- D.D. The answer should move to a different Thermodynamics and engines topic instead of fixing the misconception.
Model answer
What a good answer should say
- Field Direction answer 19ce75: A.
- The correction is to keep distinguish heat supplied, work done and internal energy change separate from the common neighbouring idea in Thermodynamics and engines, then explain the tested distinction.
- is correct because it matches Distinguish heat supplied, work done and internal energy change.
- through rotational dynamics, moment of inertia, angular velocity, torque.
Explanation
Why this works
Stem being answered: A student makes a mistake while revising Distinguish Heat Supplied Work Done And Internal Energy. Which correction is most accurate?
Route focus: engineering-physics / Thermodynamics And Engines. Key vocabulary for this item: distinguish, heat, supplied, work, done, internal, energy, change.
Option check: keep Field Direction answer 19ce75: A because it matches the stem; reject alternatives that change distinguish, heat, supplied or use a neighbouring model. The explanation should keep the answer tied to these exact words rather than a general physics summary, using units, graph evidence or equation reasoning only when they are relevant to the stem.
