Understanding Entropy: The Measure of Disorder

What is entropy?

Entropy is a measureable physical characteristic and a scientific notion that is frequently connected to a condition of disorder, unpredictability, or uncertainty. From classical thermodynamics, where it was originally recognized, through the microscopic description of nature in statistical physics, to the fundamentals of information theory, the phrase and concept are utilized in a variety of disciplines. It has numerous applications in physics and chemistry, biological systems and how they relate to life, cosmology, economics, sociology, weather science, and information systems, especially the exchange of information.

Which action represents a decrease in entropy?

A. someone arranging a deck of cards in order from aces (low) to kings (high) - This action represents a decrease in entropy because it is going from disorder to order, thus decreasing the entropy of the system.
