Final answer:
The discussion revolves around the behavior of non-azeotropic refrigerants and gases under different conditions, demonstrating their potential to leak from systems and how their phase and pressure can be controlled through temperature changes, based on principles of gas laws.

Non-Azeotropic Refrigerants and Gas Leak Inquiries
When discussing the topic of non-azeotropic refrigerants and their potential to leak from a system, it is important to understand the properties and behaviors of gases and their phase changes under varying temperatures and pressures. In particular, the exercise regarding the behavior of a high-pressure gas cylinder containing toxic gas demonstrates the principles of gas laws and the practical applications of cooling a gas to manage its pressure.
The scenario describes how a gas cylinder valve leaks due to damage, and the containment solution involves cooling the gas to reduce its pressure, making it safer to handle and repair. Using the gas law formula, we can calculate the pressure of the toxic gas at dry ice temperature assuming negligible leakage. If one-tenth of the gas escapes, a new calculation is needed to determine the adjusted final pressure. Additionally, cooling the tank to reduce the pressure to 1.00 atm is another application of gas laws where the required temperature can be mathematically found. The practicality of this method is also considered.
Freon-12's state at room temperature can be determined by comparing its boiling and melting points to the ambient temperature. Similarly, liquid ammonia's use as a solvent in Chemistry and its maintenance as a liquid by cooling with dry ice are related topics, demonstrating the manipulation of substances' phases through temperature control.
Lastly, the effectiveness of a refrigeration system, the transition from one refrigerant to another, and the properties of phase changes including sublimation provide context for understanding gas behavior in various conditions and applications.
