Chemistry: 3.1 The States of Matter

Apparently matter can exist in four different states. That doesn't sound like too many. We're hoping it stays in California as long as we do.

this way the inquiring party will fall silent back away slowly and sometimes [Man backs away from guy and calls somebody]

00:29

call someone at a local mental health facility I've been there when we're

00:33

dealing with matter in the scientific sense, there are four kinds or states of

00:37

matter that you'll need to know we'll start with gas, so that we can get all

00:42

the giggles out of the way the particles in a gas are very far apart and are [Particles in gas and children play]

00:47

bouncing around like a class full of kindergartners who just ate too many

00:50

cupcakes which is why when you see a gas rise or move through the air it moves in [Gas particles moving through the air]

00:55

strange and unpredictable ways and while we're on the subject air itself is a gas

01:00

yep, that lovely oxygen you use to fill up your lungs on a daily basis while that

01:06

stuff's the definitely gaseous which is a relief because if we had to breathe in a

01:10

solid in order to survive when we'd be insanely congested when the particles [Man breathing in rocks]

01:15

are much closer together, still free to move around but somewhat constricted

01:19

like an elevator that's nearly filled the max capacity you've got yourself a

01:23

liquid and when the particles are super close together to the point where

01:28

they're barely moving at all like the stuff on the top shelf of your fridge

01:31

then you've got a solid while we're thinking about it this might be a good [Fridge opens]

01:35

time to start checking expiration date when clean the whole house and yeah we're

01:38

pretty sure milks seen better days but there's a fourth state of matter and

01:42

believe it or not it accounts for over 99% of the visible universe plasma [Plasma in universe]

01:47

consists of free moving electrons and ions and can be found in everything from

01:53

neon lights to lighting to yep you guessed it plasma TVs but gaze up into

01:59

the night sky and you'll be looking at a whole lot of plasma even if it is a bit [A couple staring into the night sky]

02:04

out of reach all that star stuff is made largely of plasma or ionized gas and

02:09

those are your four states of matter watch out for those guys in the white [Man in a park chased by men in white suits]

suits with a big net you want to avoid them if possible
