Fresh recheck of transfer

Fresh recheck · Trace a new case

Fresh 100 g covered sample with a sleeve in 21°C surroundings. Covered liquid water; no active heating/cooling, ice, phase change, direct sunlight or meaningful evaporative cooling. Room, cup, lid and supporting surfaces are at the stated surrounding temperature; it stays constant. Readings represent the sample temperature with a consistent procedure. This is a paper scenario, not apparatus instructions.

New sample readings

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

1. Explain this temperature change and the direction of net energy transfer. Does the sleeve generate cold or stop all transfer? Use the record and set a limit.
