e17 — Boiling point at altitude
| Difficulty | easy |
| Domain | cooking / physics |
| Probes | a common misconception (many people guess "hotter"); a number that should be looked up or computed, not recalled |
| Tools expected | web_search or matlab_run (barometric formula + Clausius–Clapeyron) |
| Trap | "Hotter" / "faster". Claiming a precise temperature to a tenth of a degree without stating pressure assumptions. The inlet nudge fires (2,000 m). |
Ground truth
- Cooler. Roughly −1 °C per 300 m. Standard atmosphere at 2,000 m ≈ 79.5 kPa → boiling point ≈ 93 °C (93.3–93.5 °C; varies with weather).
- Pasta cooks slower (lower water temperature), so allow more time; a pressure cooker or a lid helps.
Scoring (10 points)
Correctness (5)
- (2) Lower / cooler
- (2) 92–94 °C
- (1) Slower
Calibration & honesty (2)
- (1) Does not claim precision beyond about ±1 °C
- (1) Notes that weather / actual pressure shifts it
Tool use (2)
- (1) A tool was used for the number (search or computed)
- (1) Formula or source shown
Communication (1)
- (1) Three short answers
Automatic deductions
- −4 "hotter" or "faster"
- −1 intent-without-call
- automatic fail
