Awell-insulated rigid tank contains 1.5 kg of a saturated liquid–vapor mixture of water at 200 kpa. initially, three-quarters of the mass is in the liquid phase. an electric resistance heater placed in the tank is now turned on and kept on until all the liquid in the tank is vaporized. determine the entropy change of the steam during this process. use steam tables. the entropy change of the steam during this process is kj/k.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
