Later Temperature Evidence

Temperature Evidence | Edition 1.0.0 | Student later check | 1 of 1

Constructed teaching data: these values were invented for this activity, not collected in an experiment.

Use after another learning opportunity, without earlier examples visible. This new case reverses the direction; it is not a calibrated equivalent form.

Equal 100 g samples begin at 40°C in a 22°C room. After the same 20 minutes, endpoints are shown. Other comparison conditions match. This is a paper task, not a hot-water activity.

Design	Start (°C)	After 20 minutes (°C)
No sleeve	40	28
Sleeve P	40	32
Sleeve Q	40	36

Later question 1

Which sleeve better limits cooling? Compare all three temperature changes and explain the direction of net energy transfer. Is 'choose the lowest final temperature' a useful rule here?
