- Understanding Chemistry on a Walk
- I wonder what they need help with. Hopefully I can be some help to them.
- I'm having a hard time understanding this. Can you come help me?

- Of course! I can help you! There are two different types of energy.
- I need some help understanding energy!
- There is also the Law of Conservation of Energy. This is the law that energy is neither created nor destroyed in reactions.
- You have potential and kinetic energy. Potential is stored while kinetic is in motion.
- I understand that, but I just don't understand exothermic and endothermic.
- Heat? Do you mean the ability to measure the transfer of thermal energy?
- First, you will need to understand heat.
- Yes! In the concept of exothermic and endothermic, heat is involved.
- Endothermic is when heat is being absorbed. The enthalpy change is positive.
- Exothermic is when heat is being released or produced. Enthalpy change is negative in this case.
- Additional to heat you have, heat of reaction. To make it simple this enthalpy change.
- This is pretty interesting to learn.
- Oh okay! Now I understand it a little better! Thank you.
- Yay! That's great! There is more to it but we will get to it next time!
- To be continued....
