Two chambers are separated by a partition. One
of the chambers is evacuated, and the other has a
volume of 1 m3 and contains steam at T 5 500°C
and P 5 10 bar. The partition is removed, allowing
the gas to expand into the evacuated chamber. No
heat transfer occurs with the surroundings. The final
steam pressure is P = 4 bar. Find
A. The mass of steam.
B. The volume of the chamber that was initially
evacuated.
C. The change in entropy of the universe resulting
from the process.
D. Re-do parts A–C, but this time, instead of steam,
assume the 1 m3 chamber was filled with an ideal
gas with Cp
* = (7/2)R.
