  1. Looking at this concept in a biological sense, free energy is the energy within a molecule that can be used to perform work. Glucose has a lot of free energy because there is a lot of energy stored within the bonds of the glucose molecule. Carbon dioxide has a much lower free energy because there is much less energy stored in its bonds.

    What is the equation for free energy?
    The equation is given as: G= H - TS Where, G = Gibbs free energy H = enthalpy T = temperature S = entropy Gibbs free energy is a state function thus it doesn’t depend on the path (i.e., its path independent entity).
    What is the definition of free energy?
    free energy. n. 1. A thermodynamic quantity that is the difference between the internal energy of a system and the product of its absolute temperature and entropy; the capacity of a system to do work, as in an exothermic chemical reaction. 2.

    What is the basic form of energy in biological system?
    The various types of energy include kinetic, potential, and chemical energy. All organisms use different forms of energy to power the biological processes that allow them to grow and survive. Kinetic energy is the energy associated with objects in motion. Potential energy is the type of energy associated with an object’s potential to do work.

    Is Gibbs free energy?
    The Gibbs free energy of a system at any moment in time is defined as the enthalpy of the system minus the product of the temperature times the entropy of the system. The Gibbs free energy of the system is a state function because it is defined in terms of thermodynamic properties that are state functions.

    • In environmental science and economics, the phrase "free energy" is sometimes used to refer to renewable resources or any energy that does not require monetary payment. Free energy may also refer to the energy that powers a hypothetical perpetual motion machine. Such a device violates the laws of thermodynamics, so this definition currently refers ...
