Yeah Oh okay More lead acid E Whatever science for

00:07

you Here we go Next question up A student wants

00:09

to see the effect that the size of the dish

00:12

has on the experiment which places to crystals each in

00:17

a separate small dish and two in one very large

00:21

dish Will which dish would reach complete diffusion first Interesting

00:32

Well the larger the dish the longer it takes for

00:35

the particles to move and separate you know so that

00:37

complete diffusion is achieved Well think of how long it

00:41

would take for a drop of red food coloring to

00:44

tint Ah whole swimming pool Red versus dropping red eye

00:48

You know a shot glass And we're talking a good

00:51

old solid red not just a you know a festive

00:53

pink right So when you have a lot of space

00:55

to effect while it's just gonna take a while Teo

00:58

really reach it all So the answer is a a 00:01:00.13 --> [endTime] small dish reaches diffusion first Whoa
