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....
