No And here's your shmoop too sure brought to you

00:05

by thermometers They always rat us out when we're playing

00:08

hookey it makes our blood boil but not at a

00:11

high enough temperature All right what happens at higher temperatures

00:15

You're the potential answers All right What happened Molecules faster

00:19

Slower Stop Are we know what happens toa us at

00:22

higher temperatures We move as little as possible But what

00:25

happens The molecules well let's Start with option b Molecules

00:29

actually move slower when you take heat away from them

00:32

Like when water turns to ice Sobhi is incorrect she's

00:35

Definitely wrong Changes in energy always change how molecules move

00:40

And even at extremely low temperatures molecules still move a

00:43

little only stop moving in what's called absolute zero The

00:47

lowest temperature that's theoretically possible So he is wrong as

00:51

well That leaves us with a heat is energy and

00:55

the more heat you have them or energy exist When

00:57

you add energy to molecules it's like given sugar two

01:00

five year olds they start bouncing around even faster than

01:03

usual And you can't wait until naptime Maybe that only

01:06

applies to one of those things But anyway the correct

01:09

answer Is a solve that one faster than a hot

01:12

molecule Just remember Adding heat is like chugging mountain dew

01:16

It adds energy It can also make you sick if

01:19

you have too much of it Hey maybe that's How 00:01:21.318 --> [endTime] we'll convince mom to let us stay home today
