Final answer:
The heat removed from the cold reservoir in a refrigerator with a COP of 3.0 and 200 J of work per cycle is 600 J. Leak rates for refrigeration equipment are regulated by the EPA, but specific values are not given in this context. Instead, the examples provided demonstrate how to apply thermodynamics principles and the ideal gas law to refrigeration and gas cylinders.
Step-by-step explanation:
The subject matter in question relates to the principles of thermodynamics and ideal gases, as they apply to refrigeration systems and the handling of pressurized gas cylinders.
To determine specific values like the heat removed per cycle from a cold reservoir, the leak rate of refrigeration equipment, or the pressure changes in a gas cylinder after temperature changes, we apply formulas derived from the laws of thermodynamics and the ideal gas law.
For instance, to compute the heat removed by a refrigerator with a coefficient of performance (COP) of 3.0, we use the relationship COP = Qc/W, where Qc is the heat removed from the cold reservoir, and W is the work input. If W is 200 J per cycle and COP is 3.0, we can rearrange the equation to find Qc = COP * W = 600 J per cycle.
Similarly, when assessing refrigeration leak rates, we consider EPA guidelines which define specific trigger rates above which maintenance or corrective action is required. In the case of high-pressure gas cylinders, applying the ideal gas law allows for calculation of changes in pressure and volume due to temperature or gas loss.
In specific situations such as leaks in industrial refrigeration equipment, the EPA might have predefined rates that denote significant leak levels requiring action, but these are not readily provided in the context of this scenario. Rather, the examples provided focus on the calculation of COP, pressure changes due to temperature variations, and the work required to transfer heat out of a refrigerated system.
