Abstract
Student interpretations of the equation for the first law of thermodynamics, Δ U = q + w, an expression defining work done on or by a gas, w = −∫ P d V, and an expression defining heat, q = ∫ C v d T were investigated through a multiple-choice survey, a free-response written survey, and interviews. The students examined had completed an undergraduate physical chemistry class in which they studied thermodynamics extensively and used these equations frequently to solve problems. The survey and interview results suggest that many students were unable to distinguish the concepts represented in the first law equation from concepts represented in the equations for work and heat. Students expressed a variety of physical interpretations for these fundamental equations. Some common misinterpretations were identified. These results suggest that far more attention needs to be placed on helping students learn the physical meaning of equations in thermodynamics courses.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
