The specific volume at a given temperature represents the volume occupied by a unit mass of a substance, typically measured in cubic feet per pound for gases. At 62 degrees Fahrenheit, the specific volume for air is approximately 0.0229 cubic feet per pound. This specific volume is influenced by temperature and pressure, with warmer air generally having a higher specific volume due to the increased kinetic energy of the molecules resulting in them spreading apart more than at lower temperatures.

In practical applications, knowing the specific volume is essential for calculations related to the efficiency of refrigeration and HVAC systems, as it directly impacts the density of air and the performance of cooling cycles. Therefore, 0.0229 cubic feet per pound accurately reflects the conditions stated in the question, making it the correct choice.
