Internal Energy given Helmholtz Free Entropy and Entropy Solution

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

FIRST Step Consider the formula

U = (S - Φ) \cdot T

Next Step Substitute values of Variables

∴

U = (71J/K - 70J/K) \cdot 85K

Next Step Prepare to Evaluate

∴

U = (71 - 70) \cdot 85

LAST Step Evaluate

∴

U = 85J
