Internal Energy using Enthalpy, Pressure and Volume Solution

Follow our step by step solution on how to calculate Internal Energy using Enthalpy, Pressure and Volume?

FIRST Step Consider the formula

U = H - P \cdot V T

Next Step Substitute values of Variables

∴

U = 1.51KJ - 38.4Pa \cdot 63m³

Next Step Convert Units

∴

U = 1510J - 38.4Pa \cdot 63m³

Next Step Prepare to Evaluate

∴

U = 1510 - 38.4 \cdot 63

Next Step Evaluate

∴

U = -909.2J

LAST Step Convert to Output's Unit

∴

U = -0.9092KJ
