Consider using the McIntosh salt mine described in Example 37.2 for adiabatic storage. Compute the energy stored if a volume of air initially at p₀ = 1 atm is compressed to p_H = 75 atm, and compare to the energy stored if the air were compressed isothermally. Takeγ = 1.4 for air. Compute the temperature of the air at pressure p_H assuming that the initial temperature was 300 K.
