Final answer:
The question deals with the safety storage recommendations for gases in containers, based on their reaction to temperature changes. It involves understanding the principles of the ideal gas law and the behavior of gases under different temperature conditions to ensure safety.
Step-by-step explanation:
The question pertains to the properties of gases and how they react to temperature changes, related to the recommendations for the safe storage of liquid and gas containers. This is a matter of safety and understanding the physical behavior of gases under the influence of temperature, which is grounded in the principles of chemistry, specifically the ideal gas law and concepts surrounding the handling of hazardous materials.
One of the examples given mentions that a gas is stored at high pressure in a cylinder which has a safety factor of 2. This implies the container can handle twice the pressure of its usual operating pressure without failing. The safety concerns arise when the container is exposed to fire, which can significantly increase the temperature and, as a result, the gas pressure inside the container. To prevent catastrophic failure, the cylinder should not be exposed to conditions that would cause the internal pressure to exceed the design threshold.
In another instance, there's a warning on a can advising to store it below 120 °F (48.8 °C), likely because the gas inside expands with heat and could cause the can to rupture or explode if the temperature rises too high. Using the ideal gas law, one can calculate the new pressure of a gas when the temperature increases, such as when a can is left in a hot car.
