In economy:
* Energy at no cost, like mechanic energy which drives wind mill, or light in solar cell which is transormed into DC electric current, i.e. wind power, water power, telluric power, and solar power
In physics, the term thermodynamic free energy denotes the total amount of energy in a physical system which can be converted to do work, in particular:
* Helmholtz free energy, the amount of thermodynamic energy which can be converted into work at constant temperature and volume. In chemistry, this quantity is called work content
* Gibbs free energy, the amount of thermodynamic energy in a fluid system which can be converted into work at constant temperature and pressure. This is the most relevant state function for chemical reactions in open containers
In engineering:
* Renewable energy, although most renewable energy sources would not normally be called free energy sources
* energy which may be directly utilized (and returned) by a device from the surroundings (electromagnetic free energy is sometimes referred to as radiant energy)
* a primary energy source that is free (i.e. does not cost anything) for consumption. Examples include wind power, water power, telluric power, and solar power
In Biology:
* Free energy (DNA) is the free energy pertaining to DNA
Free energy may also refer to:
* Free energy suppression is the notion that corporate energy interests deliberately suppress technologies that may provide energy at very little cost. Remaining so-far-unexploited forces of nature which are well documented in the scientific literature include telluric currents, atmospheric electricity, earth batteries, and pressure system changes
* The energy from fantastical forces considered perpetual motion. These devices utilize quantum vacuum perturbation, quantum vacuum energy, rotating magnets, as well as some purported methods to crack hydrogen

What is the difference between Helmholtz free energy and Gibbs free energy, and how do they relate to each other in the context of thermodynamics?
Helmholtz free energy and Gibbs free energy are both measures of the energy available to do work in a system. The main difference is that Helmholtz free energy is used for systems at constant temperature and volume, while Gibbs free energy is used for systems at constant temperature and pressure. In the context of thermodynamics, Helmholtz free energy is often used to determine the maximum work that can be extracted from a system, while Gibbs free energy is used to predict whether a reaction will occur spontaneously. Both energies are related through the equation: G H - TS, where G is the change in Gibbs free energy, H is the change in enthalpy, T is the temperature, and S is the change in entropy.
Does osmosis increase free energy in a system?
No, osmosis does not increase free energy in a system. Osmosis is a process where solvent molecules move from an area of low solute concentration to an area of high solute concentration, but it does not directly affect the free energy of the system. The free energy change in osmosis depends on the pressure and temperature of the system.
What is the amount of available energy that can be used to promote change do work is called?
The amount of available energy that can be used to promote change and do work is called free energy. This is the energy that is available to do useful work in a system.
What is the energy band in which free electrons exist?
Free electrons exist in the conduction band, which is the highest energy band in a material where electrons are free to move and conduct electricity.
What is the symbol for free-energy change?
The symbol for free-energy change is ΔG (delta G). It represents the change in Gibbs free energy during a chemical reaction, which determines whether the reaction is spontaneous or non-spontaneous.
What is the difference between Gibbs free energy and standard free energy, and how do they relate to each other in chemical reactions?
Gibbs free energy and standard free energy are both measures of the energy available to do work in a chemical reaction. The main difference is that Gibbs free energy takes into account the temperature and pressure of the system, while standard free energy is measured under specific standard conditions. In chemical reactions, the change in Gibbs free energy determines whether a reaction is spontaneous or non-spontaneous. If the Gibbs free energy change is negative, the reaction is spontaneous, while a positive change indicates a non-spontaneous reaction. The relationship between Gibbs free energy and standard free energy lies in the fact that the standard free energy change can be used to calculate the Gibbs free energy change under any conditions.
What the free energy will be if the temperature is kept uniform in a system?
If the temperature is kept uniform in a system, the free energy will remain constant. Free energy, also known as Gibbs free energy, depends on temperature and is a measure of the system's ability to do work. When the temperature is held constant, there is no change in the free energy of the system.
Does sugar free mean energy free?
No
What represents the difference between the free energy content of hte reaction and the free energy content of the products?
The Gibbs free energy change (∆G) of a reaction represents the difference between the free energy content of the reactants and the free energy content of the products. A negative ∆G indicates that the reaction is spontaneous and can proceed without requiring external energy input.
What is an inexpensive energy resource?
There are some energy sources, such as wind energy, solar energy, and geothermal energy, that are available in abundance - basically for free. But please note that there is always a cost to convert such energy types into something useful. The energy is free; converting it into useful energy to run machinery is not free.
Is the big bang a form or example of free energy?
The Big Bang is not an example of free energy. Free energy typically refers to the energy available to do work, whereas the Big Bang was the initial explosion that marked the beginning of the universe and is not related to the concept of free energy.
What is the connection between spontaneous reactions and free energy?
Spontaneous reactions release free energy. If a reaction is spontaneous, it means that it can occur without outside intervention because the products are at a lower energy state than the reactants, and the excess energy is released as free energy. The change in free energy (ΔG) for a spontaneous reaction is negative.
Is wind energy cheap?
Wnd energy is free
What is the name of free energy's debut album?
Free Energy's debut album's name is "Stuck On Nothing".
What is the significant application of Helmholtz free energy?
how does helmholtz free energy applies to real world examples
Can you go from activation energy from free energy?
Did you mean to ask "Can you go from activation energy tofree energy"?The answer might be found in looking at the definition of the coefficient of performance (COP), which states something like this:COP is the ratio of work or useful output (possibly free energy) to the amount of work or energy input (activation energy).If the COP is greater than one, then more energy is being produced than is required to produce it. One might argue that there is no such thing as free energy if you have to work for it.We are surrounded by free energy. Is the energy produced by a water wheel free? Is the energy produced by a wind turbine free? Is the electricity produced by a solar collector free? The energy is free for the collecting, but the method for collecting it has a cost of some kind.Check wikipedia for "trompe". There is a theory that the Giza pyramid has an underground structure that was designed as a trompe.
