Which specific volume reading shows a decrease from temperatures of 59 to 58 degrees Fahrenheit?

In the context of refrigeration, specific volume is defined as the volume occupied by a unit mass of a substance, typically in cubic feet per pound for gases. As the temperature of a gas decreases, its specific volume typically also decreases due to the closer packing of gas molecules at lower energetic states.

When examining the question about the temperature decrease from 59 to 58 degrees Fahrenheit, it is essential to understand that cooler temperatures generally correlate to lower specific volume readings for a given refrigerant or gas.

The provided answer, which indicates a specific volume reading of 0.0223, represents that trend accurately. As the temperature drops, the gas contracts, and therefore, the specific volume reflects this reduced volume per unit mass. In this case, the significant decrease in specific volume from temperatures of 59 to 58 degrees Fahrenheit is identified by the value of 0.0223, effectively showing how the physical properties of gas behave when subjected to temperature changes.

This relationship between temperature and specific volume is a fundamental principle in thermodynamics and refrigeration, reinforcing why it is crucial to select the reading that demonstrates this characteristic change effectively.
