Answer :
In response to the statement provided, which is related to Kelvin Planck's statement regarding the efficiency of heat engines, the correct answer is:
- True
Explanation:
1. Kelvin Planck's statement, also known as the Kelvin-Planck statement of the second law of thermodynamics, asserts that it is impossible for any heat engine to operate with 100% efficiency.
2. This statement implies that no heat engine can take heat from a single source (reservoir) and convert all of that heat into work. There will always be some heat rejected to a cooler reservoir during the process.
3. In simpler terms, it means that not all the input heat energy can be completely converted into useful work by a heat engine. Some heat will always be wasted in the process.
4. This principle highlights the limitations imposed by the laws of thermodynamics on the efficiency of heat engines, emphasizing that perfect efficiency is unattainable.
Therefore, the statement that "no heat engine can exchange heat with a single reservoir and produce an equivalent amount of work" aligns with Kelvin Planck's principle and is true.
