In scenario X, a device that can measure the volume of sound is placed on the ground in vacuum. An object, also in vacuum, is released from rest above the ground and falls so that it strikes the ground next to the device. In scenario Y, the experiment is repeated in the same way, except the device and object are not in vacuum. In terms of energy transfer, which of the following claims is correct about the volume of sound produced by the object when it hits the ground in scenario X and scenario Y? a. The measured volume in scenario X is greater than in scenario Y, because sound waves are not impeded by particles in the air as they travel through vacuum. Thus, the sound waves have more energy in scenario X than in scenario Y.
b. The measured volume in scenario X is less than in scenario Y, because sound waves must have a medium to transfer energy. Thus, the sound waves have more energy in scenario X than in scenario Y.
c. The measured volume in scenario X is the same as in scenario Y, because the experiment is identical in both scenarios except for the amount of air where the experiments are conducted. Thus, the sound waves have equal energies.
d. The answer cannot be determined, because the recorded volume of sound is not related to the energy contained within the sound wave.

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
