   Nov 28, 2021 · Entropy is a measure of the randomness or disorder of a system. Its symbol is the capital letter S. Typical units are joules per kelvin (J/K). Change in entropy can have a positive (more disordered) or negative (less disordered) value. In the natural world, entropy tends to increase.

   This student guide introduces us to the ways in which entropy can be under-stood. It emphasizes conceptual foundations and exemplary illustrations and distinguishes among different kinds of entropy: thermodynamic entropy, the entropy of classical and quantized statistical systems, and the entropy of infor-mation.

   Entropy is a central concept for many reasons, but its chief function in thermodynamics is to quantify the irreversibility of a thermodynamic process. Each term in this phrase deserves elaboration. Here we define thermodynamics and process; in subsequent sections we take up irreversibility.

   How to think about entropy?

   • In this lecture, we discuss many ways to think about entropy. The most important and most famous property of entropy is that it never decreases Here, Stot means the change in entropy of a system plus the change in entropy of the surroundings. This is the second law of thermodynamics that we met in the previous lecture.

   What is entropy change?

   • Entropy and entropy change are abstract ideas used to explain why changes occur in the direction that we observe under specific conditions. Entropy is often described as a measure of disorder of a system, but it is actually a thermodynamic property that can be used to determine the energy not available for work in the process.

   Does entropy increase or decrease?

   • In the natural world, entropy tends to increase. According to the second law of thermodynamics, the entropy of a system only decreases if the entropy of another system increases. The simple definition is that entropy is that it is the measure of the disorder of a system. An ordered system has low entropy, while a disordered system has high entropy.
