Question 37Refrigeration & AC - QMED
70% to passThe amount of HCFC-123 in a storage cylinder is measured by what means?
Avolume
Bsaturation pressure
Csaturation temperature
Dweight
AI Explanation
The correct answer is D) weight. The amount of HCFC-123 in a storage cylinder is measured by weight because HCFC-123 is a liquid refrigerant, and the most accurate way to determine the quantity in a cylinder is to measure its mass. Volume and pressure/temperature measurements can vary due to temperature changes, but the weight of the refrigerant remains constant. This is in line with standard industry practices and regulations for handling and storing refrigerants like HCFC-123. The other options are incorrect because volume, saturation pressure, and saturation temperature would not provide an accurate and reliable measurement of the HCFC-123 quantity in the cylinder.
