The formula to calculate the Helmholtz Free Energy is:
\[ A = U - T \cdot S \]
Helmholtz free energy is a thermodynamics concept in which the thermodynamic potential is used to measure the work of a closed system. Internal Energy is the energy contained within a thermodynamic system. Temperature is the degree or intensity of heat present in a substance or object. Entropy is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work.
Let's assume the following values:
Using the formula:
\[ A = 1210 - 86 \cdot 16.8 = -234.8 \]
