An inventor claims to have developed a new closed, sealed battery that can produce a maximum reversible work of 3.80 kJ. The total energy contained in the battery is 2.00 kJ with a total entropy of 7.5150 J/K.
If the ground state total energy and total entropy are 100. J and 0.5660 J/K, respectively, what ground state temperature is required to meet the inventor's maximum reversible work claim?
