Question 159Refrigeration & AC - 1st Asst/Chief

The correct answer is C) hydrostatic pressure of the expanding liquid. When a refrigerant container is overfilled, the expanding liquid refrigerant creates high hydrostatic pressure within the container. As the liquid refrigerant expands, it takes up more volume, resulting in a buildup of internal pressure. This high pressure can be extremely dangerous, as it increases the risk of the container rupturing or exploding. The other options are incorrect because they do not directly address the root cause of the pressure buildup, which is the expansion of the liquid refrigerant.
