Kinetic mechlor theory states that gas particles are in constant motion, and that kinetic energy that the gases have is directly proportional to the temperature of the system.
00:17
Now, if we assume room temperature, we can start modeling what the motions of these are different, atomic species would look like based on this theory.
00:37
So first one, we're just looking at solid iron.
00:41
Well, solid iron is definitely not a gas, and so there's no motion involved at all.
00:47
So if i just draw a bunch of iron atoms, just one after the other, i'm not gonna draw all 10.
00:55
You can extrapolate from this, but you can essentially see just like, you know, something tight, together.
01:03
Adams tightly together, not moving a lot of space outside, but definitely no space between them as they are bonded together.
01:13
This would be for just solid iron and key part here is solid.
01:20
For the next system, we're looking at liquid water.
01:26
Well, you know, we know from a macro molecular point of view or macroscopic point of view that water, that's not good, that's too high, water does move, liquid water does move, and there is some space because, you know, you can put your hand through it, so it slides aside for you.
01:49
There, and it's what we call some sort of vander walls, contact with one another, but they still slide easily past one another.
01:58
I'm kind of keeping out the bottom of the container.
02:02
This box, we have just to emphasize that they are affected by gravity and that there's like a liquid layer here and then the air would be just right above.
02:14
I'm not going to draw all of them, but just to be a point that they slide, they still move across one another.
02:22
So water in a liquid form.
02:26
Liquid.
02:30
Then we look at water as a vapor.
02:33
Now, vapor is the gaseous form of water.
02:37
Water, so they still retain kind of this triangle configuration with two hydrazine one oxygen.
02:51
But, you know, they're flying everywhere, and there's a lot of space in between them.
02:57
That's why even though it's a humid room, there's lots of water vapor in the air, we can still walk through it.
03:04
There's a lot of space between them.
03:07
So this is water vapor, that is a gaseous state.
03:11
They're moving and what i'm not also showing is that they're constantly colliding with the container now in theory it would not in theory in fact it would actually stick to the side of the walls but kinetic molecular theory is assuming a kind of a you know direct bounce off of any substance and they're just bouncing all the perfect collisions all right.
03:42
So the next one we're looking at is water and helium.
03:46
So we've got water vapor, and we have a helium gas vapor, and healing gas.
03:53
So helium also is a gas.
03:55
And the other thing about balloons that are flying around in the air helps them float.
04:01
It's a diatomic molecule.
04:02
So we'll draw two of those.
04:04
But we're still talking about gas, both of them are in a gas state.
04:08
So we give them a lot of space in between.
04:12
They're bonded to, the atoms are bonded to each other, but the molecules themselves are kind of flying everywhere.
04:19
And i'll put another water molecule on top just to emphasize that.
04:23
These things are just going everywhere.
04:25
They're bouncing around, hitting containers, hitting each other...
