Which of the following would cause entropy to decrease?
Explanation: Entropy decreases when the number of moles of gas decreases during a reaction. In the case of the correct answer, the number of moles of gas decreases from two to one.
Answer: The products becoming more ordered than the reactants.
- Freezing, and condensation.
- Reactions that combine two molecules into one (addition)
- Reactions that reduce the number of gas molecules.
- Reactions that make a molecule more rigid (going from long chains to inflexible rings)
In an endothermic reaction, the external entropy (entropy of the surroundings) decreases.
The evaporation of water. The conversion of `CO_2` gas into dry ice.
The entropy of a system decreases only when it interacts with some other system whose entropy increases in the process. That is the law.
The second law of thermodynamics. Which process is an example of entropy decreasing? Steam condenses to liquid water.
An organism that can interact with its surroundings can expel entropy via heat, to gain local order and reduce local entropy. Global disorder still increases, but for that organism, the ability to locally reduce entropy is literally a matter of life and death. An obvious example of this principle is humans.
Entropy generally increases when a reaction produces more molecules than it started with. Entropy generally decreases when a reaction produces fewer molecules than it started with.
Entropy increases as temperature increases. An increase in temperature means that the particles of the substance have greater kinetic energy. The faster-moving particles have more disorder than particles that are moving slowly at a lower temperature.
Which of the following changes decreases the entropy of a sample?
condensation, which involves the transformation of a gas to a liquid state and releasing heat to outside the system, decreases the entropy of a system.
Entropy decreases when work is done on a system. specifically, adiabatic work or by inputting heat without changing the temperature ideally.
Entropy is generated everywhere and always (and thus overall increased), at any scale without exception (including life processes, open systems, micro-fluctuations, gravity, or entanglement). Entropy cannot be destroyed by any means, at any scale, and thus, entropy cannot overall decrease.
- 1) Change in Phase (Physical State)
- 2) Change in Temperature.
- 3) Change in Number of Particles (especially for Gases)
- 4) Mixing of Particles.
Answer and Explanation: a) anabolic reactions. CORRECT - this would decrease the entropy of the cells by producing new tissues with greater organization (graeter order) from more disordered building block molecules.
Entropy increases as you go from solid to liquid to gas, and you can predict whether entropy change is positive or negative by looking at the phases of the reactants and products. Whenever there is an increase in gas moles, entropy will increase.
- Phase of Matter. The most significant factor affecting entropy is the phase of matter: ...
- Higher Temperature, Higher Entropy. ...
- Higher Volume, Higher Entropy. ...
- Higher Number of Particles, Higher Entropy. ...
- A Change in the Number of Moles of Gas. ...
- Phase Changes. ...
- A Change in Complexity of the Substances.
As, the entropy of universe decreases then it will start shrinking.
