Internal Energy using Helmholtz Free Energy Solution

Follow our step by step solution on how to calculate Internal Energy using Helmholtz Free Energy?

FIRST Step Consider the formula

U = A + T \cdot S

Next Step Substitute values of Variables

∴

U = 1.1KJ + 86K \cdot 16.8J/K

Next Step Convert Units

∴

U = 1100J + 86K \cdot 16.8J/K

Next Step Prepare to Evaluate

∴

U = 1100 + 86 \cdot 16.8

Next Step Evaluate

∴

U = 2544.8J

LAST Step Convert to Output's Unit

∴

U = 2.5448KJ
