Entropy using Helmholtz Free Energy Solution

STEP 0: Pre-Calculation Summary

Formula Used

Entropy = (Internal Energy-Helmholtz Free Energy)/Temperature
S = (U-A)/T
This formula uses 4 Variables

Variables Used

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.
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.
Helmholtz Free Energy - (Measured in Joule) - Helmholtz free energy is a thermodynamics concept in which, the thermodynamic potential is used to measure the work of a closed system.
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

Internal Energy: 1.21 Kilojoule --> 1210 Joule (Check conversion here)
Helmholtz Free Energy: 1.1 Kilojoule --> 1100 Joule (Check conversion here)
Temperature: 298 Kelvin --> 298 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S = (U-A)/T --> (1210-1100)/298

Evaluating ... ...

S = 0.369127516778524

STEP 3: Convert Result to Output's Unit

0.369127516778524 Joule per Kelvin --> No Conversion Required

FINAL ANSWER

0.369127516778524 ≈ 0.369128 Joule per Kelvin <-- Entropy

S = (U-A)/T

Define Entropy?

Entropy, the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work. Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system.

How to Calculate Entropy using Helmholtz Free Energy?

Entropy using Helmholtz Free Energy calculator uses Entropy = (Internal Energy-Helmholtz Free Energy)/Temperature to calculate the Entropy, Entropy using Helmholtz Free Energy formula is defined as a measure of the disorder or randomness in a thermodynamic system, reflecting the amount of energy unavailable for doing work at a constant temperature and volume. Entropy is denoted by S symbol.

How to calculate Entropy using Helmholtz Free Energy using this online calculator? To use this online calculator for Entropy using Helmholtz Free Energy, enter Internal Energy (U), Helmholtz Free Energy (A) & Temperature (T) and hit the calculate button. Here is how the Entropy using Helmholtz Free Energy calculation can be explained with given input values -> 0.369128 = (1210-1100)/298.
