Inter =between; forces between one molecule and another molecule
Intra =within; forces between atoms within a molecule; holds the molecule together
Intra
force/bond between hydrogen and oxygen atoms WITHIN the molecule
Inter
force between two water molecules
Endothermic= when heat is absorbed; when the new state/substance needs more energy so it absorbs energy (heat) from whatever it touches; when you touch it, it feels cold because it's taking the energy (heat) from your hand.
​
Example: as water evaporates it needs energy (heat) in order to become a gas so it takes it from whatever it touches. This is why sweating is a cooling process! The liquid water on your skin wants to evaporate but it needs energy in order to do it so it takes the energy (heat) from your body.
Exothermic =think exit; when heat is released (or exits); when the new state/substance is at a lower energy so energy is released; when you touch it, it feels hot because energy (heat) is being released onto your hand.
​
Example: as water condenses (goes from a gas to a liquid) it has to release energy in order for the particles to move closer together and form the liquid.

I am SO SORRY! I forgot that we haven't covered the mol yet! Please do NOT stress over the ideal gas law. If it doesn't make any sense that's because I failed you and completely forgot you needed that prior information. Honestly, keep this in your notes but ignore it until after unit 5a.
Error in Video!!
The answer to #1 should be 72.5 mol
