Which consequence results when a Carnot heat engine approaches absolute zero?

💡 Explanation

As the cold reservoir approaches absolute zero, finite temperature differences create unbounded thermal efficiency increases, because efficiency depends inversely on the cold reservoir temperature; therefore, the efficiency increases without limit, rather than decreasing or becoming impossible under ideal conditions.
