JOAN CARTAN-HANSEN, HOST:

00:06.333 --> 00:07.733 position:15% line:84.67% size:75%
The state of matter depends

00:07.733 --> 00:09.066 position:27.5% line:84.67% size:62.5%
upon how its atoms

00:09.066 --> 00:10.066 position:30% line:84.67% size:60%
are positioned.

00:10.066 --> 00:11.333 position:12.5% line:84.67% size:77.5%
So, a good way to think about

00:11.333 --> 00:12.800 position:10% line:84.67% size:80%
the states of matter is to think

00:12.800 --> 00:14.100 position:30% line:84.67% size:60%
about football.

00:14.100 --> 00:15.600 position:10% line:84.67% size:80%
In a solid state, the atoms are

00:15.600 --> 00:16.833 position:20% line:84.67% size:70%
tightly packed together.

00:16.833 --> 00:18.100 position:15% line:84.67% size:75%
They don't move too much and

00:18.100 --> 00:19.066 position:32.5% line:84.67% size:57.5%
stay in place.

00:19.066 --> 00:20.366 position:15% line:84.67% size:75%
When a football team is in a

00:20.366 --> 00:21.866 position:15% line:84.67% size:75%
tight formation, the players

00:21.866 --> 00:23.266 position:10% line:84.67% size:80%
don't move too much and are in a

00:23.266 --> 00:24.966 position:12.5% line:84.67% size:77.5%
set formation, hence, this is

00:24.966 --> 00:26.866 position:12.5% line:84.67% size:77.5%
like a solid state of matter.

00:26.866 --> 00:28.200 position:10% line:84.67% size:80%
In a liquid state, the atoms can

00:28.200 --> 00:29.933 position:10% line:84.67% size:80%
move around each other, allowing

00:29.933 --> 00:31.233 position:15% line:84.67% size:75%
matter to flow and take the

00:31.233 --> 00:32.600 position:20% line:84.67% size:70%
shape of its container.

00:32.600 --> 00:33.966 position:10% line:84.67% size:80%
In football terms, this is when

00:33.966 --> 00:35.400 position:10% line:84.67% size:80%
part of the team can move around

00:35.400 --> 00:37.266 position:10% line:84.67% size:80%
to adapt to the flow of the game

00:37.266 --> 00:38.966 position:20% line:84.67% size:70%
by dodging and weaving.

00:38.966 --> 00:40.700 position:10% line:84.67% size:80%
In a gas state, atoms are widely

00:40.700 --> 00:42.133 position:10% line:84.67% size:80%
spread apart and can move freely

00:42.133 --> 00:43.533 position:20% line:84.67% size:70%
often colliding with one

00:43.533 --> 00:44.466 position:37.5% line:84.67% size:52.5%
another.

00:44.466 --> 00:45.866 position:12.5% line:84.67% size:77.5%
In an open football play, the

00:45.866 --> 00:47.200 position:10% line:84.67% size:80%
players are spread out and move

00:47.200 --> 00:48.066 position:37.5% line:84.67% size:52.5%
quickly.

00:48.066 --> 00:49.333 position:15% line:84.67% size:75%
They are independent of one

00:49.333 --> 00:50.733 position:12.5% line:84.67% size:77.5%
another, yet still part of the

00:50.733 --> 00:52.566 position:15% line:84.67% size:75%
same team working together.

00:52.566 --> 00:54.700 position:12.5% line:84.67% size:77.5%
So, the states: solid, liquid

00:54.700 --> 00:56.033 position:10% line:84.67% size:80%
and gas depend upon the position

00:56.033 --> 00:57.566 position:22.5% line:84.67% size:67.5%
and movement of atoms.

00:57.566 --> 00:59.900 position:15% line:84.67% size:75%
It's a winning combination.

00:59.900 --> 01:01.166 position:17.5% line:84.67% size:72.5%
