In order to be able to use the Energy-InteractionModelto make sense of the behavior of a heat pack, it is useful to divide the overall process (cycle) into multiple sub-processes. Use the following sub-processes:
Initial conditions action Final conditions
a) liquid at 100˚C taken out of boiler liquid at 23˚C
b) liquid at 23˚C triggered (and insulated) solid/liquid at 54˚C shortly after
triggering (in mixed state)
c) solid/liquid at 54˚C sitting on table solid at 23˚C
d) solid at 23˚C placed in boiler solid/liquid at 54˚C
e) solid/liquid at 54 ˚C left in boiler liquid at 100 ˚C
Make four energy-system diagrams, one for each sub-process a), c), d), and e), but NOT b). Also, make an Temperature v. Energy-added diagram for each process. Make sure you can describe each process in your own words using both of the representations.
