What is the law of entropy?
Entropy is the scientific concept of disorder and randomness that has many broad applications across different branches of physics. While it is not a law itself, it is central to understanding the Second Law of Thermodynamics, as objects that are in thermodynamic equilibrium are at their highest state of entropy.
Does temperature increase as latitude decrease?
No, temperatures generally decrease as latitudes increase. The equator (30° to 40°C) is 0° latitude while the poles (0° to -40°C) are at 90° latitude.
How does the entropy change in the reaction 2C2H2(g) plus 5O2(g) 4CO2(g) plus 2H2O(l)?
In the reaction 2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(l), the entropy decreases. This is because the reactants consist of gaseous molecules, which have higher entropy due to their greater freedom of movement, while the products include liquid water, which has lower entropy. Additionally, there is a reduction in the number of gas molecules from 7 (2 C2H2 + 5 O2) to 4 (4 CO2), further contributing to the decrease in disorder. Overall, the transition from gas to liquid and the reduction in the number of gas molecules results in a net decrease in entropy.
Why is entropy irreversible?
It's not that entropy can't be reversed, it's that the entropy of the universe is always increasing. That means that while you can reduce the entropy of something, the entropy of another thing must go up even more so that in total, the entropy goes up.
Why do biological organisms violate the laws of thermodynamics?
Biological organisms do NOT violate the laws of thermodynamics. Some people mistakenly think that because they assemble into complex structures they must be in violation of the 2nd law. This is not true. The 2nd law does not preclude the assembly of complex structure, it says that any such process will produce more entropy in the universe - so the decrease in entropy of the plant, animal, bacteria, or biological organism is accompanied by an even greater INCREASE in the entropy of the universe.
Is it possible to reverse entropy?
Entropy is a measure of disorder in a system, and according to the second law of thermodynamics, entropy tends to increase over time. While it is theoretically possible to temporarily decrease entropy in a localized system, reversing entropy on a large scale is not feasible based on our current understanding of physics.
Why can't entropy be destroyed?
The reason that entropy increases is related to statistics. It is possible in theory that a process occurs in such a way that entropy decreases, but this is so unlikely that it will never happen in practice.
What does the entropy of a reaction describe?
The amount of randomness in the system
What describes the entropy change of gas reaction?
if there is an increase in the number of gas molecules , then ^S > 0
Does the movement of particles increase or decrease while vaporating?
Increase
What does delta S 0 mean in a reaction?
The system becomes more random.
What is the relationship between entropy and energy?
Entropy is a measure of disorder or randomness in a system, while energy is the capacity to do work. The relationship between entropy and energy is that as energy is transferred or transformed in a system, the entropy of that system tends to increase. This is known as the second law of thermodynamics, which states that in any energy transfer or transformation, the total entropy of a closed system will always increase over time.
Does the distance from the sun increase or decrease while moving away from the equator?
Increase
How does temperature affect the volume of substance?
An increase in temperature will cause an increase in volume, while a decrease in temperature will cause a decrease in volume.
What is the relationship between exothermic reactions and entropy changes in a chemical system?
In a chemical system, exothermic reactions release heat energy, while entropy changes refer to the disorder or randomness of molecules. Exothermic reactions typically lead to an increase in entropy, as the released heat energy can increase the movement and randomness of molecules in the system.

Which one will be affected if the frequency increase?
If the frequency increases, the wavelength of the wave will decrease while the energy of the wave will increase.
