In thermodynamics, entropy is a measure of the non-convertible energy (ie. energy not available to do work) inside a closed system. The concept of free energy involves tapping into an inexhaustible source of energy available to do work. Thus, in a system generating free energy, entropy would never increase, and the usable energy could be siphoned off forever. This illustrates, succinctly, why a free energy system can never exist.

∙ 15y agoOf the four laws of Thermodynamics the last two include entropy.
Now you have to understand that the laws of thermodynamics start off at zero so the last two laws are number two and three.
2: Entropy is always increasing
3: The Entropy of a pure crystalline solid is 0

What happens to entropy when energy is transformed?
There is always an increase in the entropy of the universe.
What kind of energy is lost in any energy transformation?
Entropy.
How is energy permantely lost?
To feed the rise in Entropy. Enthalpy is a constant, but Entropy is always increasing.
Where an decrease in thermal energy is occurring?
entropy
Does entropy increase or decrease due to friction?
Entropy is a measure of disorder. Heat is a very low order form of energy. Friction produces heat energy and hence entropy tends to increase due to friction.
When does entropy increases?
Entropy increases when ever energy is used up. Energy cannot be destroyed, but it is always lost in the form of unusable energy. Entropy is the % of unusable energy compared to usable energy in a given system.
What are some connections between 2nd law of thermodynamics and living things?
relationship between the thermodynamic quantity entropy
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.

What happens to entropy when energy is transformed?
There is always an increase in the entropy of the universe.
Entropy involves losing energy over time?
that is not a full questionif it was does entropy involve losing energy ever time, then yes
What is the relationship between solar energy and global winds'?
The relationship between the two is their energy source which is the sun.
Is there a relationship between radiant energy and electrical energy?
there is a relationship they produce temperature.
What is the relationship between the enthalpy h and entropy s of a reaction that is spontaneous at higher temperatures but not at lower temperatures?
-H, +S
What kind of energy is lost in any energy transformation?
Entropy.
When graphing enthalpy and entropy what variables are included?
Temperature and energy are two of the variables included when graphing enthalpy and entropy. Enthalpy is made up of the energy, pressure, and volume of a system. Entropy is a way to determine the different ways energy can be arranged.
How is energy permantely lost?
To feed the rise in Entropy. Enthalpy is a constant, but Entropy is always increasing.

entropy
