Q: At what temperature does the Gibbs Free Energy change from negative to positive?
Solution: The Gibbs Free Energy changes from negative to positive at the transition temperature, where the system shifts from one phase to another.
Steps: 5
Step 1: Understand that Gibbs Free Energy (G) is a measure of the energy available to do work in a system.
Step 2: Know that when G is negative, the process is spontaneous (it can happen on its own).
Step 3: Recognize that when G is positive, the process is non-spontaneous (it needs energy to happen).
Step 4: Identify that the transition temperature is the specific temperature at which the system changes from one phase (like solid to liquid) to another.
Step 5: Realize that at this transition temperature, the Gibbs Free Energy changes from negative to positive.
