Question

The cylinder assembly of an FCS 2001 cryogenic sampler should stabilize in what per square inch gauge (psig) range before it is sent to the area lab for analysis?

a. 1,000-1,500.
b. 1,200-1,700.
c. 1,300-1,800.
d. 1,500-2,000.

Answer 1

The specific pressure range for an FCS 2001 cryogenic sampler is not provided in the reference material, but the pressure is known to decrease when the temperature is lowered, according to the Ideal Gas Law.

Step-by-step explanation:

The cylinder assembly of an FCS 2001 cryogenic sampler should stabilize in a certain range of pressure before being sent to the lab for analysis. Unfortunately, the specific pressure range for the FCS 2001 is not provided in the referenced material. However, using the principle of gas behavior under cooling from the provided examples, we can infer that the pressure in a sealed container will decrease when the temperature drops. Following the Ideal Gas Law, pressure and temperature are directly proportional when volume and the amount of gas are constant.

For instance, if a high-pressure gas cylinder is cooled to dry ice temperature to reduce the pressure for safe repair, the final pressure can be calculated assuming there is no phase change and a negligible amount of gas leaks. Similar calculations can be conducted to determine the pressure after a portion of the gas escapes or to find the required temperature to achieve a target pressure.
