When boiling water, many energy changes are involved between and within the molecules. Explain what happens as the water boils and evaporates as a gas based on your understanding of kinetic, potential, and activation energy. The prompts provided in Step 2 will guide you through this activity. (100 min)
Instructions:
Step 1: Analyze
Review the required learning materials for this lesson.
Potential, Kinetic, Free and Activation Energy
Step 2: Respond
Prepare a 250-300 word piece that defines energy and describes potential, kinetic, free, and activation energy within the context of the scenario given. Your response should answer the following prompts:
- When water is heated, what happens to its kinetic energy and how does this affect the molecules?
- As energy is added to the water, what happens to the forces between the water molecules, and how does this affect the potential energy?
- What is the concept of free energy, and how does the change in potential energy affect the free energy of boiling water?
- What is activation energy, and how is it affected by free energy? How does the activation energy change as the water is heated?
