The short answer is yes, entropy can be decreased in certain systems. However, this is only possible with the input of energy or work. In isolated systems, entropy always increases.
Entropy is a measure of disorder or randomness in a system. It is a thermodynamic quantity that describes the distribution of energy within a system.
Yes, the second law of thermodynamics states that the entropy of a closed system always increases over time. This is known as the law of increasing entropy.
Yes, living organisms are able to decrease entropy within their own bodies by taking in energy from their surroundings and using it to maintain and increase order.
Entropy and information are closely related. In information theory, entropy is a measure of the uncertainty or randomness of a system, and can also be interpreted as the amount of information that is missing. Higher entropy means higher uncertainty and less information.
