"Heat cannot be itself flow from a body at lower temperature to a...
Heat cannot flow itself from a lower temperature to a body of higher temperature (for cyclic process this is Kelvin-Planck statement). This corresponds to second law of thermodynamics.

"Heat cannot be itself flow from a body at lower temperature to a...
Explanation:
Heat transfer from a body at a lower temperature to a body at a higher temperature goes against the second law of thermodynamics. This law states that heat cannot flow spontaneously from a colder body to a hotter body. This principle is crucial in understanding the direction of heat transfer and forms the basis of many processes in nature.
Second Law of Thermodynamics:
- The second law of thermodynamics states that heat naturally flows from a hotter body to a colder body, and not the other way around.
- It implies that heat transfer occurs in the direction of decreasing temperature, ensuring that energy is distributed efficiently.
Consequence:
- The statement "Heat cannot itself flow from a body at lower temperature to a body at higher temperature" is a consequence of the second law of thermodynamics.
- This principle is essential in various applications, such as refrigeration, engines, and heat exchangers, where heat transfer directionality plays a crucial role.
In conclusion, the second law of thermodynamics governs the direction of heat transfer and ensures that energy flows efficiently in systems. Understanding this law is fundamental in the study of thermodynamics and various engineering applications.
