Will this energy ledger warm or cool?
Two sealed packs can start at the same temperature yet change differently. Track energy spent and returned in a safe model.
Purpose-made packs can change temperature
Some rearrangements release energy to their surroundings; others absorb it. Use only purpose-made packs or supervised demonstrations—never mix unknown household chemicals.
Separating old partners costs energy
Move model chips into break-cost slots. Pulling old partners apart requires energy.
Forming new partners returns energy
Form new interactions and watch model chips return to the surroundings.
Only the net balance decides
Compare spent and returned model units. A surplus can warm; a deficit must be supplied from somewhere.
A new exact ledger
This safe computer mixture needs seven model chips to separate old partners and returns five when new partners form. The thermometer still waits at the middle.
both flows meet one balance · thermometer still neutral
Commit before the new setup runs.
