Internal Energy given Gibbs Free Entropy Solution

Follow our step by step solution on how to calculate Internal Energy given Gibbs Free Entropy?

FIRST Step Consider the formula

U = ((S - Ξ) \cdot T) - (P \cdot V T)

Next Step Substitute values of Variables

∴

U = ((71J/K - 70.2J/K) \cdot 298K) - (80Pa \cdot 63L)

Next Step Convert Units

∴

U = ((71J/K - 70.2J/K) \cdot 298K) - (80Pa \cdot 0.063m³)

Next Step Prepare to Evaluate

∴

U = ((71 - 70.2) \cdot 298) - (80 \cdot 0.063)

Next Step Evaluate

∴

U = 233.359999999999J

LAST Step Rounding Answer

∴

U = 233.36J
