Answer :
Final answer:
The correct statement is that the nitrogen tank must be outfitted with a pressure regulator.
Explanation:
The correct statement regarding the use of nitrogen is A. The nitrogen tank must be outfitted with a pressure regulator. This is important because nitrogen is stored under high pressure and needs to be released at the appropriate pressure for different applications.
Option B is incorrect as nitrogen can be added to systems at various pressure levels, not just in a deep vacuum. Option C is also incorrect because nitrogen can be added to both partially charged and fully charged HVACR systems. Option D is not true as dry nitrogen is actually an inert gas and does not follow a pressure/temperature relationship like volatile gases.

Final answer:
The correct statement is that the nitrogen tank must be outfitted with a pressure regulator. Nitrogen is used in applications like HVACR systems where a regulator is necessary for safe and controlled release. Other statements about nitrogen being added only to systems in a deep vacuum or to fully charged systems, and being a volatile gas are incorrect.
Explanation:
The correct statement regarding the use of nitrogen is: A. The nitrogen tank must be outfitted with a pressure regulator. This is because nitrogen can be stored at high pressures and a pressure regulator is necessary to ensure that it is released at a safe and usable pressure. When working with nitrogen in systems such as HVACR (Heating, Ventilation, Air Conditioning, and Refrigeration), it is standard practice to use a regulator to control the flow of nitrogen.
B. Nitrogen must only be added to systems that are in a deep vacuum is not a true statement, although it is often introduced in systems under vacuum to check for leaks due to its inert nature which does not interact with system components. C. Nitrogen must only be added to fully charged HVACR systems is also incorrect as nitrogen is typically used before the system is fully charged, during testing and purging.
D. Dry nitrogen is a volatile gas that follows a pressure/temperature relationship is not true because dry nitrogen is neither volatile nor does it always follow a simple pressure/temperature relationship since it is generally inert under standard conditions.
