 So you might be thinking as I was just now why what how does this happen? Why would these mall? Why would these atoms and molecules rearrange themselves like this into something new? How does that take place and it takes place because of a super important fact about all atoms and molecules? They all have kinetic energy, and I'm gonna go to a new page these guys are moving kinetic energy is the energy of Movement So I have kinetic energy. I have this awesome Yoga ball chair that I'm sitting on and I'm I'm not I can't bounce too much or I will make myself seasick Looking at myself in this video, but I have kinetic energy Okay, I have a ton of kinetic energy because my hands are moving all over the place and my face is moving and my mouth is moving all of that is kinetic energy on top of all of my kinetic energy that is happening because of my massive Muscles that are contracting and moving me all over the place On top of all of that kinetic energy in me Every single atom in my giddy up Also has kinetic energy. It is moving. I'm going to show you a picture of Oh Come on now Why is that not okay? I'm gonna try something. I'm gonna pause and see if I can come back when I fixed a tech issue I hope you did not see that all of that I have no idea if I'm back to recording or if you saw all that I'm gonna take my chances So this is a really cool image of an atom a single particle that is How this is an image of how that single particle is moving the measure of a Particles movement the more movie a particle is the more active the more movement there is in a particle the Higher the temperature of that thing Okay, I'm gonna try to go back To giving you notes because I want to write that down for you. Look at work that time Okay, um more movement higher kinetic energy is A higher temperature This is easy to visualize if you think about like a cup of tea if you drop a piece of a drop of food coloring in a boiling hot cup of tea The food coloring the dye is gonna move around a lot The the particles in the boiling or hot water are Moving more than the particles if you did the same thing you dropped The what the food coloring into cold water You know, it's not gonna move around as much because those colder particles aren't moving as much less movement less kinetic energy Equals lower temperature and I want to be sure that you're clear that when I say Movement is that kinetic energy is temperature. That's molecular So that like seriously we are made of atoms and Even though I look at my table and I'm like, yeah, nothing's moving on my table Those atoms that make up my table Absolutely are moving and a measure of how much they're moving is the temperature of my table This is a concept that is sort of Bizarre and will take us a little bit of time to get cozy with but I think we'll see like we'll talk about it a lot And it's relevant forever all through all of our biology classes The last thing that I want to talk or show you Why this is so weird it didn't it did it again? Let's see if it comes back It did that's cool. I wanted to show you my friend the tardigrad This guy also known as a moss piglet or a water bear this guy has Capacity to stay alive and get so cold that his atoms almost stopped moving the temperature at which Atoms stop moving is called absolute zero and it's negative 273 degrees Celsius. That's like Are you kidding me? It's really cold We cannot get anything that cold. We've never gotten anything down to this idea of absolute zero But this guy has gotten really close to absolute zero and has then warmed up and Come back to life. I tell you this only because that is freaking cool and Those guys they're like little wild Microscopic critters that do live in moss. I've never seen a live one I kind of think that my kid got to like hunt for tardigrads in moss When he was taking AP bio, I'm gonna have to investigate and find out if that is true because I really would love to find one Okay, that's our first lecture on chemistry Make sure you're cozy because I'm coming back at you to talk even more about specific things to life for carbohydrates proteins DNA RNA that stuff's coming at us in the next lecture. Okay. Bye. Bye
