STEP 0: Pre-Calculation Summary
Formula Used
Internal Energy = Enthalpy-Pressure*Volume
U = H-P*VT
This formula uses 4 Variables
Variables Used
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.
Enthalpy - (Measured in Joule) - Enthalpy is the thermodynamic quantity equivalent to the total heat content of a system.
Pressure - (Measured in Pascal) - Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
Volume - (Measured in Cubic Meter) - Volume is the amount of space that a substance or object occupies or that is enclosed within a container.
STEP 1: Convert Input(s) to Base Unit
Enthalpy: 1.51 Kilojoule --> 1510 Joule (Check conversion here)
Pressure: 38.4 Pascal --> 38.4 Pascal No Conversion Required
Volume: 63 Cubic Meter --> 63 Cubic Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
U = H-P*VT --> 1510-38.4*63
Evaluating ... ...

U = H-P*VT

What is Enthalpy?

Enthalpy is a property of a thermodynamic system, defined as the sum of the system's internal energy and the product of its pressure and volume. As a state function, enthalpy depends only on the final configuration of internal energy, pressure, and volume, not on the path taken to achieve it.

What is Duhem’s Theorem?

For any closed system formed from known amounts of prescribed chemical species, the equilibrium state is completely determined when any two independent variables are fixed. The two independent variables subject to specification may in general be either intensive or extensive. However, the number of independent intensive variables is given by the phase rule. Thus when F = 1, at least one of the two variables must be extensive, and when F = 0, both must be extensive.
