Chapter 88 The Law of Entropy Increase
It could be because Green Star wasn’t very precise in its expression, so Wandering didn’t fully understand.
Lu Chen felt that using the "Law of Entropy Increase" would be more convenient to explain this phenomena, so he immediately started to explain it to Wandering.
Simply put, "entropy" is actually a special term in thermodynamics, which measures the degree of disorder in a system or system.
That is to say, entropy can be understood as a measurement unit just like length in meters or temperature in degrees; the former describes clearly visible numerical values, while entropy describes the degree of disorder in a system.
When the degree of disorder in a system decreases, it is called entropy reduction.
When the degree of disorder in a system increases, it is called entropy increase.
The Law of Entropy Increase proposed because of entropy increase is the second law of thermodynamics.
The Law of Entropy Increase assumes that in an isolated system, the overall trend of its degree of disorder will always tend toward increasing entropy, which is an irreversible process.
When applied to temperature, it shows that heat will spontaneously transfer from a hotter object to a cooler one; when applied to events, order will spontaneously tend toward disorder. Both share a common factor: the occurrences are natural processes and irreversible.
Therefore, if we view the Universe as an isolated system, the transfer of heat from hotter regions to cooler ones is a spontaneous process. Once the temperature throughout the Universe evens out, it will reach a state of thermal equilibrium and heat death, with entropy at its maximum and the system’s disorder at its peak.
