Solution

  3. This means that it is impossible to construct an engine whose sole purpose is to convert the heat from a high-temperature source/reservoir into an equal amount of work.

Hence, Kelvin- Planck's statement states that it is impossible to devise a heat engine that takes heat from the hot reservoir.
