Look at all the nonmoving molecules.

00:00:10.960 --> 00:00:13.160
ICE MOLECULES: Nope, we're still vibrating.

00:00:14.240 --> 00:00:15.420
Whoa!  Who said that?

00:00:15.580 --> 00:00:19.980
ICE MOLECULES: Me, AKA, the vibrating molecules.

00:00:21.000 --> 00:00:25.780
LIQUID WATER MOLECULES: Yeah, us too. Except we can move around pretty freely.

00:00:25.880 --> 00:00:28.620
Oh great. The next thing you know the air is going to talk.

00:00:28.720 --> 00:00:32.260
AIR MOLECULES: Yep, you called it. We can move around completely freely.

00:00:32.540 --> 00:00:34.620
What do you mean by freely?

00:00:34.960 --> 00:00:37.900
ICE MOLECULES: I can only vibrate.

00:00:37.900 --> 00:00:44.160
LIQUID WATER MOLECULES: Well, I can move more freely than ice, but I can only move very limitedly.

00:00:44.720 --> 00:00:49.180
AIR MOLECULES: I can move completely freely. So I can go wherever I want.

00:00:49.440 --> 00:00:56.340
So, let me get this straight...Solids vibrate in place; liquids move, but not freely; and gas moves 100% freely.

00:00:57.820 --> 00:00:59.300
ALL MOLECULES: Yep.

00:00:59.300 --> 00:01:01.680
That's great. I really
learned something new today.

00:01:01.780 --> 00:01:03.960
ALL MOLECULES: You're welcome!
