  2. Examples of decreased entropy - Physics Forums

    www.physicsforums.com/threads/examples-of-decreased-entropy.484467

    Examples of decreased entropy . In summary, the conversation discusses natural non-living processes where entropy decreases locally. Examples include crystallization, evaporation, and refrigeration. However, it is noted that these examples may not be good representations of decreasing entropy as the overall system still experiences an increase ...

  3. When does entropy increase and when does it decrease?

    socratic.org/questions/when-does-entropy-increase-and-when-does-it-decrease

    The system entropy (S) by the modern definition is the amount of energy dispersal in a system. Entropy (S) by the modern definition is the amount of energy dispersal in a system. Therefore, the system entropy will increase when the amount of motion within the system increases. For example, the entropy increases when ice (solid) melts to give water (liquid). It will even increase more when ...

  4. What is an example of entropy from everyday life? | Socratic

    socratic.org/questions/what-is-an-example-of-entropy-from-everyday-life

    Entropy is a measure of the energy dispersal in the system. We see evidence that the universe tends toward highest entropy many places in our lives. A campfire is an example of entropy. The solid wood burns and becomes ash, smoke and gases, all of which spread energy outwards more easily than the solid fuel. Ice melting, salt or sugar dissolving, making popcorn and boiling water for tea are ...

  5. What would cause entropy to decrease in a reaction? | Socratic

    socratic.org/questions/what-would-cause-entropy-to-decrease-in-a-reaction

    Ex. gases + liquids --> liquids. This also applies to moles. If, for example, there are only gases on both sides of the reaction, but the products have less moles of gas than the reactants, entropy is decreasing. Ex. 2SO2 + O2 --> 2SO3. The reaction is going from 3 moles of gas to 2 moles of gas. So there is a decrease in entropy.

  6. Entropy Decrease: Sample Phenomena Explained - Physics Forums

    Entropy Decrease: Sample Phenomena Explained. Domenicaccio. Jun 3, 2008. decrease Entropy. In summary, entropy can decrease locally at the expense of increased entropy elsewhere, as seen in the example of an air conditioner. However, this decrease in entropy requires work and ultimately leads to an overall increase in entropy in the universe.

    2NO(g) +O2(g) → 2NO2(g) has a total of 3 moles of gas on the reactants' side and only 2 moles of gas on the products' side. This means that this reaction will show a decrease in entropy. Answer link. Process A) shows a decrease in entropy. > The entropy of a system increases whenever its particles have more freedom of motion.

  9. What is an example of increasing entropy? - Socratic

    socratic.org/questions/what-is-an-example-of-increasing-entropy

    Explanation: Entropy is nature's way of increasing disorder in any system and thereby the entirety of the universe.The wood starts as a single, solid object. Fire consumes the wood, releasing energy along with carbon dioxide and water vapor, and leaving a pile of ashes. Answer link. Burning wood. Entropy is nature's way of increasing disorder ...

  10. Second Law of Thermodynamics - Physics - Socratic

    socratic.org/physics/thermodynamics/second-law-of-thermodynamics

    The Second Law of Thermodynamics says “the entropy of the universe increases during any spontaneous process”. That means that Energy spontaneously disperses from being localized to becoming spread out if it is not hindered from doing so. Few examples: A rock will fall if you lift it up and then let go. Hot frying pans cool down when taken off the stove. Iron rusts in the air. Air in a high ...

  11. Entropy - Chemistry - Socratic

    socratic.org/chemistry/thermochemistry/entropy

    Entropy is the quantitative measure of spontaneous processes and how energy disperses unless actively stopped from doing so. Entropy is highly involved in the second law of thermodynamics: An isolated system spontaneously moves toward dynamic equilibrium (maximum entropy) so it constantly is transferring energy between components and increasing its entropy.
