3 kg of ammonia at its critical state is placed in a constant-volume container, which is then cooled until the temperature is 300 K. How a much energy was transferred as heat from the ammonia in this process, and what tank volume is occupied by liquid at the end of the process? Use the tables in Appendix A.7 for data.
