Which pressure corresponds to the lowest temperature listed in the data?

• A. 16.2" hg
• B. 17.8" hg
• C. 19.7" hg
• D. 16.6" hg

Answer: (D)

The choice that corresponds to the lowest temperature listed in the data is the option with the lowest pressure measurement. In refrigeration systems, there is a direct relationship between pressure and temperature; as pressure decreases, the temperature also decreases. This principle is often highlighted in temperature-pressure charts for refrigerants, which show that lower pressures correspond to lower temperatures. In this context, the measurement of 16.6 inches of mercury (hg) represents the lowest pressure among the available choices, leading to the conclusion that it aligns with the lowest temperature indicated in the data. By correlating these two variables, we understand that the pressure must be lowered to achieve a lower temperature, which is essential for efficient refrigeration operation and system performance.
