Assume an isentropic expansion of helium (3 4) in a gas turbine.Since helium behaves almost as an ideal gas, use the ideal gas law to calculate outlet temperature of the gas (T 4,is).

The more disorder within a system, the greater the entropy.

The different levels of depth of the sea Culture Scientists Other Category v t e Entropy articles Introduction History Classical entropy Statistical entropy v t e Entropy is a scientific concept, as well as a measurable physical property, that is most commonly associated with a state of disorder, randomness, or uncertainty. These examples serve to illustrate how the entropy change in a reaction can be predicted: Cl2(g) Cl2(l) Cl 2 ( g) Cl 2 ( l) The entropy is decreasing because a gas is becoming a liquid.

The formation of mountains, ranges and plateausĪ hurricane is an example of entropy in nature.

Examples of entropy in nature The term entropy comes from a Greek word that means “transformation.” Below is a worked example of calculating the entropy change for a process that involves both a temperature change and a phase change. Obtaining energy from the environment gives order to the body. The term was coined by the French physicist Léon Brillouin as an antonym of the word entropy.Īn example of negentropy occurs in the human body, which obtains from its environment the necessary food to stay alive.

The neuentropy or negative entropy is the energy that an open system obtains from the environment to be able to develop and thus keep its natural levels of entropy lower and achieve order.
