entropy

• Termo científico que pode designar a medida da desordem ou da incerteza em um sistema, especialmente em termodinâmica e na teoria da informação.

A scientific term that can refer to a measure of uncertainty or disorder in a system, particularly in thermodynamics and information theory.

1. Thermodynamic quantityC1formalscientific

   A measure of the disorder or randomness in a closed system, representing the amount of energy unavailable for work.

   Entropia

   • The second law of thermodynamics states that entropy in an isolated system always increases.
   • Entropy is often described as the tendency of systems to move toward greater disorder.
   • Calculating the entropy change helps engineers design more efficient engines.

2. Measure of uncertaintyC1formalscientific

   In information theory, a numerical measure of the unpredictability or uncertainty of an outcome.

   Medida de incerteza

   • High entropy in a data stream indicates a high level of randomness.
   • The entropy of a fair coin toss is one bit.
   • Shannon's entropy formula is fundamental to data compression algorithms.
