WebNov 28, 2024 · 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.
