SUMMARY
A negative heat capacity object increases in temperature when it radiates energy and decreases in temperature when it absorbs energy. Such an object cannot achieve thermal equilibrium with a positive temperature reservoir because energy transfer occurs from the negative temperature system to the positive temperature system, leading to a decrease in entropy. The discussion clarifies that thermal equilibrium represents a state of maximal entropy, and systems with differing temperature signs will always move away from equilibrium.
