group of students has given five unknown metals and a

00:19

toaster oven They're tasked with ranking the thermal conductivity values

00:24

of the five medals which of the following pieces of

00:27

lab equipment should they use select two answers aren't a

00:30

thermometer purple being bounds of watering stand all right Well

00:34

usually cooking appliances aren't used in science but there was

00:38

that one time when we roasted marshmallows over a bunsen

00:40

burner That experiment taught us that it's really tough to

00:43

get cooked marshmallows off of countertops and that mrs smith's

00:46

face turns really red when she's mad so we got

00:49

some pretty important results there In this experiment though we're

00:52

determining thermal conductivity which is a measure of how well

00:56

a material conducts heat To rank the thermal conductivity of

00:59

these materials the students need to see how efficiently each

01:01

piece of metal transfers heat and a triple beam balance

01:05

Isn't gonna help with that at all Neither is a

01:07

ring stand This thing so answer is b andy won't

01:10

be used in this experiment We don't have anything against

01:13

them They just don't have much to do with temperature

01:15

and know What we need to do is slap these

01:17

medals in the toaster oven crank it up and start

01:20

the stopwatch After a period of time we take the

01:23

medals out of the oven wearing our kiss the cook

01:25

oven mitts because safety comes first and we love those

01:28

mitts and take their temperature with thermometer the hottest medals

01:32

will be the best conductors and the not so hot

01:35

medals will be the worst and the hot pocket will

01:38

be a nuclear inferno Inside melting off the skin inside 00:01:42.288 --> [endTime] our mouth out
