What statement represents the ideal gas law?
Official USCG Answer & Rule Citation
Correct Answer: Option C — For a given mass of a gas, the volume is inversely proportional to its pressure and directly proportional to its temperature.
The Ideal Gas Law, PV=nRT, dictates that for a constant mass, pressure and volume are inversely proportional (Boyle's Law), while volume and absolute temperature are directly proportional (Charles's Law). This relationship is fundamental to understanding thermodynamics in shipboard compressed air systems and engine cycle analysis.
