model might be more useful than the other depending on the context.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

the dissolution of polymer can be thermodynamically described in 2 steps.
