Answer :
Final answer:
The second law of thermodynamics explains entropy, heat flow, and the irreversible nature of certain processes.
Explanation:
The second law of thermodynamics states that the total entropy of a system either increases or remains constant in any spontaneous process; it never decreases. An important implication of this law is that heat transfers energy spontaneously from higher- to lower-temperature objects, but never spontaneously in the reverse direction.
Entropy is a measure of disorder or randomness in a system. The second law of thermodynamics emphasizes that in natural processes, the total entropy of an isolated system tends to increase over time.
Heat flow from a warmer object to a colder one is a clear example of the second law of thermodynamics in action, showcasing the irreversible nature of certain processes dictated by this fundamental law.
