AP Physics 2: 2.5 Properties of Objects and Systems

group of students has given five unknown metals and a

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

of the five medals which of the following pieces of

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

thermometer purple being bounds of watering stand all right Well

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

that one time when we roasted marshmallows over a bunsen

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

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

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

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

determining thermal conductivity which is a measure of how well

a material conducts heat To rank the thermal conductivity of

these materials the students need to see how efficiently each

piece of metal transfers heat and a triple beam balance

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

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

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

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

and know What we need to do is slap these

medals in the toaster oven crank it up and start

the stopwatch After a period of time we take the

medals out of the oven wearing our kiss the cook

oven mitts because safety comes first and we love those

mitts and take their temperature with thermometer the hottest medals

will be the best conductors and the not so hot

medals will be the worst and the hot pocket will

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