## Internal Energy given Helmholtz Free Entropy and Entropy Solution

STEP 0: Pre-Calculation Summary
Formula Used
Internal Energy = (Entropy-Helmholtz Free Entropy)*Temperature
U = (S-Φ)*T
This formula uses 4 Variables
Variables Used
Internal Energy - (Measured in Joule) - The internal energy of a thermodynamic system is the energy contained within it. It is the energy necessary to create or prepare the system in any given internal state.
Entropy - (Measured in Joule per Kelvin) - Entropy is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work.
Helmholtz Free Entropy - (Measured in Joule per Kelvin) - The Helmholtz Free Entropy is used to express the effect of electrostatic forces in an electrolyte on its thermodynamic state.
Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.
STEP 1: Convert Input(s) to Base Unit
Entropy: 71 Joule per Kelvin --> 71 Joule per Kelvin No Conversion Required
Helmholtz Free Entropy: 70 Joule per Kelvin --> 70 Joule per Kelvin No Conversion Required
Temperature: 85 Kelvin --> 85 Kelvin No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
U = (S-Φ)*T --> (71-70)*85
Evaluating ... ...
U = 85
STEP 3: Convert Result to Output's Unit
85 Joule --> No Conversion Required
85 Joule <-- Internal Energy

## What is Debye–Huckel limiting law?

The chemists Peter Debye and Erich Hückel noticed that solutions that contain ionic solutes do not behave ideally even at very low concentrations. So, while the concentration of the solutes is fundamental to the calculation of the dynamics of a solution, they theorized that an extra factor that they termed gamma is necessary to the calculation of the activity coefficients of the solution. Hence they developed the Debye–Hückel equation and Debye–Hückel limiting law. The activity is only proportional to the concentration and is altered by a factor known as the activity coefficient. This factor takes into account the interaction energy of ions in the solution.
