STEP 0: Pre-Calculation Summary
Formula Used
Change in Internal Energy = Final Potential Energy-Initial Potential Energy
ΔU = Efinal-Einitial
This formula uses 3 Variables
Variables Used
Change in Internal Energy - (Measured in Joule) - The Change in 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.
Final Potential Energy - (Measured in Joule) - Final Potential Energy is the final energy that is stored in an object due to its position relative to some zero position.
Initial Potential Energy - (Measured in Joule) - Initial Potential Energy is the initial energy that is stored in an object due to its position relative to some zero position.
STEP 1: Convert Input(s) to Base Unit
Final Potential Energy: 55 Joule --> 55 Joule No Conversion Required
Initial Potential Energy: 25 Joule --> 25 Joule No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ΔU = Efinal-Einitial --> 55-25
Evaluating ... ...
ΔU = 30
STEP 3: Convert Result to Output's Unit
30 Joule --> No Conversion Required
30 Joule <-- Change in Internal Energy

## What is Thermochemistry?

Thermochemistry is the study of the heat energy which is associated with chemical reactions and/or phase changes such as melting and boiling. A reaction may release or absorb energy, and a phase change may do the same. Thermochemistry focuses on the energy exchange between a system and its surroundings in the form of heat. Thermochemistry is useful in predicting reactant and product quantities throughout the course of a given reaction. In combination with entropy determinations, it is also used to predict whether a reaction is spontaneous or non-spontaneous, favorable or unfavorable.
