Fresh check — use after the named response practice
Fresh check · The goal now is to limit cooling. Fresh 100 g water samples begin at 34°C in a 22°C room. Two 20-minute trials use matching cups, lids, and measurement methods.
Final water temperatures after 20 minutes
Constructed teaching data: these values were invented for this activity, not collected in an experiment.
Trial | Start (°C) | Sleeve P: final °C | Sleeve Q: final °C |
|---|---|---|---|
1 | 34 | 29 | 31 |
2 | 34 | 28 | 30 |
3. Which sleeve better limits cooling? Give both temperature drops. Is the lowest endpoint the best choice for this goal?
