How are internal energy change( at constant pressure) , free energy change and entropy change related to one another?

Explanation

To understand the relationship between internal energy change (at constant pressure), free energy change, and entropy change, we can break it down step by step.

### Step-by-Step Solution:

1. **Understanding Internal Energy Change (ΔU)**:
- Internal energy (ΔU) is a measure of the total energy contained within a system. It includes kinetic and potential energy at the molecular level.
- At constant pressure, the change in internal energy can be related to the change in enthalpy (ΔH).
