Final answer:
The maximum test pressure for leak testing a low pressure sensor with nitrogen is typically set at 10 PSIG to prevent damage and ensure safety. The subject of the question is Physics, specifically within the context of ideal gas law applications.
Step-by-step explanation:
When leak testing a low pressure sensor with nitrogen, it is important to not exceed the maximum test pressure, which is typically set at 10 PSIG. This safety threshold ensures that the equipment is not damaged during the testing process. Exceeding this pressure could cause the sensor to fail, leading to inaccurate readings or potential safety hazards.
While not directly related to the question, if you deal with high-pressure gas cylinders such as one containing 50.0 L of toxic gas at a pressure of 1.40 × 107 N/m², cooling the gas (without a phase change or gas leak) can lead to pressure reduction. This can be calculated using the ideal gas law, which states that for a given mass of gas, the pressure varies directly with the absolute temperature if the volume remains constant.
