If work is don adiabatically on a system will the internal energy increase or decrease?
If work is done adiabatically on a system, the internal energy will increase. This is because adiabatic processes do not involve the exchange of heat with the surroundings, so any work done on the system will directly contribute to an increase in its internal energy.
The system that shows a decrease in entropy is?
There is at least one non spontaneous reactions occuring in the particular system. So someone or something has to shred energy in order to continue the procedure.
Do spontaneous processes increase or decrease the stability of a system?
Spontaneous processes tend to increase the stability of a system by moving it towards a lower energy state or higher entropy state, which are more stable configurations. This is in line with the second law of thermodynamics, which states that systems tend towards higher disorder and lower energy to increase stability.
Definition of endothermic?
Endothermic reactions or processes absorb heat from their surroundings to proceed, causing a decrease in temperature of the surroundings. Energy is required for the reaction to occur, resulting in a decrease of the system's internal energy.
Does crystallisation increase or decrease entropy?
Entropy is the tendency of the universe to become more disorganized. Photosynthesis decreases entropy because it takes a larger number of reactants and converts them into a more organized form of energy, where there are less products than reactants. 6 H2O + 6 CO2 ---> C6H12O6 + 6 O2
What happens to entropy when energy is transformed?
When energy is transformed, entropy can either increase or decrease. For example, in many energy transformations, such as combustion or chemical reactions, entropy tends to increase due to the dispersal of energy. However, in some processes, such as certain phase changes, entropy can decrease.
What is the impact of a change in entropy at constant volume on a system's thermodynamic properties?
A change in entropy at constant volume affects a system's thermodynamic properties by influencing its internal energy and temperature. When entropy increases, the system becomes more disordered and its internal energy and temperature also increase. Conversely, a decrease in entropy leads to a decrease in internal energy and temperature. Overall, changes in entropy at constant volume play a crucial role in determining the behavior and characteristics of a system in thermodynamics.
Can you decrease the entropy if yes then how and if not then why?
You cannot reduce entropy because entropy increases (Second Law of Thermodynamics), if you could, we could have perpetual motion. When work is achieved energy is lost to heat. The only way to decrease the entropy of a system is to increase the entropy of another system.
What the example of the statement the entropy of the universe can never decrease?
If a source of heat energy starts radiating from a point and continues without stop the entropy around that point will never decrease. As sun is the endless heat energy radiating source and surrounding's of that is known as universe accepted by everybody. So this is the example for the statement ' the entropy of the universe can never decrease.'
What does wasted energy add too?
Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe. The wasted energy is related to entropy - one way to express the Second Law of Thermodynamics is to say that there are irreversible processes (in terms of energy), another is that "entropy increases". However, entropy is not energy; it is not measured in Joule, but in Joule/Kelvin. In any case, you might say that when energy is wasted, entropy increases.Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe.

Is forbidden based on the second law of thermodynamics?
It forbids heat to move from a cold region to a hot regions spontaneously (you have to "pump" it there - meaning you have to do work to get it to move that direction). Alternatively - it forbids any natural/spontaneous process to DECREASE the entropy of the universe.
When the total amount of entropy or disorder in the Universe will it increase or decrease?
The total amount of entropy in the universe will always increase according to the second law of thermodynamics, which states that the entropy of an isolated system will tend to increase over time. This means that the overall disorder in the universe will continue to grow as processes occur and energy is dispersed.
How does entropy apply to cells?
Entropy in cells refers to the level of disorder or randomness within a biological system. In the context of cells, entropy can represent the randomness of molecules and structures present within the cell. Cells use energy to maintain order and decrease entropy to carry out biological processes effectively. Imbalances in cellular entropy can lead to dysfunction and disease.
What would cause entropy to decrease in a reaction?
The products becoming more ordered than the reactants
What does negative change in entropy indicate?
The system has become more ordered.

What types of reaction would decrease the entropy within a cell?
Synthesis reactions such as dehydration synthesis. For a reaction to proceed the there must be a net decrease in the Gibbs Free Energy of the system. The Gibbs Free Energy is made up of two terms: Enthalpy or Heat Content H Entropy S For a reaction in which the entropy is increasing to proceed there would have to be a sufficient release of heat content (enthalpy) such that Change in Free Energy G would be negative, ie decrease...
