JOAN CARTAN-HANSEN, HOST:

3
00:00:06,333 --> 00:00:07,733
The state of matter depends

4
00:00:07,733 --> 00:00:09,066
upon how its atoms

5
00:00:09,066 --> 00:00:10,066
are positioned.

6
00:00:10,066 --> 00:00:11,333
So, a good way to think about

7
00:00:11,333 --> 00:00:12,800
the states of matter is to think

8
00:00:12,800 --> 00:00:14,100
about football.

9
00:00:14,100 --> 00:00:15,600
In a solid state, the atoms are

10
00:00:15,600 --> 00:00:16,833
tightly packed together.

11
00:00:16,833 --> 00:00:18,100
They don't move too much and

12
00:00:18,100 --> 00:00:19,066
stay in place.

13
00:00:19,066 --> 00:00:20,366
When a football team is in a

14
00:00:20,366 --> 00:00:21,866
tight formation, the players

15
00:00:21,866 --> 00:00:23,266
don't move too much and are in a

16
00:00:23,266 --> 00:00:24,966
set formation, hence, this is

17
00:00:24,966 --> 00:00:26,866
like a solid state of matter.

18
00:00:26,866 --> 00:00:28,200
In a liquid state, the atoms can

19
00:00:28,200 --> 00:00:29,933
move around each other, allowing

20
00:00:29,933 --> 00:00:31,233
matter to flow and take the

21
00:00:31,233 --> 00:00:32,600
shape of its container.

22
00:00:32,600 --> 00:00:33,966
In football terms, this is when

23
00:00:33,966 --> 00:00:35,400
part of the team can move around

24
00:00:35,400 --> 00:00:37,266
to adapt to the flow of the game

25
00:00:37,266 --> 00:00:38,966
by dodging and weaving.

26
00:00:38,966 --> 00:00:40,700
In a gas state, atoms are widely

27
00:00:40,700 --> 00:00:42,133
spread apart and can move freely

28
00:00:42,133 --> 00:00:43,533
often colliding with one

29
00:00:43,533 --> 00:00:44,466
another.

30
00:00:44,466 --> 00:00:45,866
In an open football play, the

31
00:00:45,866 --> 00:00:47,200
players are spread out and move

32
00:00:47,200 --> 00:00:48,066
quickly.

33
00:00:48,066 --> 00:00:49,333
They are independent of one

34
00:00:49,333 --> 00:00:50,733
another, yet still part of the

35
00:00:50,733 --> 00:00:52,566
same team working together.

36
00:00:52,566 --> 00:00:54,700
So, the states: solid, liquid

37
00:00:54,700 --> 00:00:56,033
and gas depend upon the position

38
00:00:56,033 --> 00:00:57,566
and movement of atoms.

39
00:00:57,566 --> 00:00:59,900
It's a winning combination.

40
00:00:59,900 --> 00:01:01,166
