∙ 9y ago
When the temperature and pressure is uniform in a system then the free energy is the portion of the system's energy that is able to perform work. It is related to the total enthalpy.

What is the value equal to the enthalpy minus temperature times entropy?
free energy. this is gibbs free energy in biological systems
What affects the magnitude of delta G?
Delta G is the change in Gibbs free energy. Gibbs Free energy is defined as:- G= H-TS at constant temperature so the factors ar the change in enthalpy (H) and entropy (S)
Use the Gibbs free energy equation shown below to determine the temperature range for which the decomposition of KCIO4 is spontaneous?
97.6 - 98
According to the Gibbs free energy equation G H - T S when could a high temperature make a reaction that was nonspontaneous at low temperature spontaneous?
when h and s are both positive
Is it true that non spontaneous process never happens in universe?
non spontaneous process happen in the universe but energy has to be provided to them . the free energy change of such processes are positive . the amount of temperature has to be increased to carry out such reactions
Does osmosis increase free energy in a system?
If you have a system in which the process of osmosis is spontaneously taken place, the free energy of the system is being reduced. Free energy is the one doing the job.
Gibbs quantity of maximum possible work?
Gibbs free energy represents the maximum reversible work that can be extracted from a system at constant temperature and pressure. It combines the system's enthalpy and entropy to predict whether a reaction is spontaneous. The change in Gibbs free energy (∆G) determines whether a reaction will proceed spontaneously or not.
What is the value equal to the enthalpy minus temperature times entropy?
free energy. this is gibbs free energy in biological systems
How to calculate helmholtz free energy for ideal gas?
F=U-TS where F is the Free energy, U is energy, T temperature and S entropy
How is temperature related to energy.?
Temperature is related to energy in that temperature is actually the measure of kinetic energy. Almost all types of energy produce some type of heat.
How is sound energy and thermal energy alike?
Temperature is what is used to measure thermal energy The more thermal energy a substance has, the more warmer it will be. So when the temperature is high, there is a lot of thermal energy Thermal energy is just energy. It refers to the energy of the molecules. Temperature is just a measurement
What is free energy?
Free EnergyFree energy may refer to: 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 powerIn 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 containersIn 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 powerIn biology:* Free energy (DNA) is the free energy pertaining to DNAFree 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------------------honest slavery
How is Gibbs Free energy evaluated?
Enthalpy (H) or thermal energy content of the system entropy (S) of the degree of disorder of a system.
What is the connection between spontaneous reactions and free energy?
A reaction occurs spontaneously when free energy is negative, ie the disorder of the system is increasing
What is the relationship between entropy and energy?
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.
What distribution pattern describes pine trees on a pine free farm?
Uniform.
What happens to the entropy of a system as more heat is added beyond the boiling point?
Fundamentally, if the entropy of a system increases, that means that the energy of the system ("normalized" to , i.e., divided by the temperature of the system) has become more "dispersed" or "dilute". For instance, if a system increases its volume at constant energy and temperature, then the energy per unit temperature is now more "dilute", being spread over a larger volume. All spontaneous processes result in a "dilution" or "spreading out" of the energy of the universe. The more dilute the energy of a system is (the higher the entropy of that system) the harder is is to harness that energy to do useful work. Another useful way of thinking about entropy is to consider it as a measure of the amount of information needed to completely specify the state of a system. Ultimately, this means how much information is needed to specify the positions and momenta of every particle in the system.
