Statement: No Heat Engine can operate with 100% efficiency (convert h...
- It is not possible to construct an engine that does nothing but convert heat into useful work.
- If some of the heat must go into raising the temperature of a sink, not all of it can be converted into work.
- If work is being done by the heat engine, the object on which work is being done is not isolated from the heat engine. Unless it is at the same temperature as the heat source, heat will flow conventionally from the heat source to the object on which work is being done, and the object's temperature will rise.

Explanation:
Reasons for the statement being TRUE in all conditions:
- According to the second law of thermodynamics, no heat engine can have 100% efficiency.
- This law states that heat always flows from a hot body to a cold body, and some of the heat is always lost in the form of waste heat during the conversion process.
- The efficiency of a heat engine is limited by the Carnot efficiency, which depends on the temperature difference between the heat source and the sink.
- Even in ideal conditions, where friction and other losses are minimized, the efficiency of a heat engine cannot exceed a certain limit.
Implications of the statement:
- This limitation poses a challenge for engineers and scientists in designing more efficient heat engines.
- It also highlights the importance of developing alternative energy sources that are not limited by the constraints of traditional heat engines.
Conclusion:
In conclusion, the statement that no heat engine can operate with 100% efficiency holds true in all conditions due to the fundamental principles of thermodynamics. While advancements in technology may improve efficiency, there will always be limitations to how efficiently heat energy can be converted to mechanical work.
