Transcript

00:01

No And here's your shmoop douceur brought to you by

00:05

soup We wanted to come up with some good soup

00:08

puns but we wouldn't want a broth or you so

00:10

we'll just curry on with the question You stick a

00:13

metal spoon into a bowl of hot soup you notice

00:16

the spoon gets very warm as well This is an

00:18

example of what type of heat transfer and here are

00:21

potential answers I conducted back too many memories right He

00:25

also known as energy can move from one place to

00:27

another in a variety of waste Seriously you should see

00:30

it do the tango let's look at a conduction conduction

00:33

occurs when heat moves from one object to another providing

00:36

that the two objects are in direct contact with each

00:39

other Sound familiar Let's Cover all our bases though and

00:42

see what other fancy footwork he is capable of There's

00:45

conviction which covers one of fluid like era water transfers

00:48

heat as it moves Think of a pot of boiling

00:50

water Water at the bottom which is closest to the

00:53

burner gets hot rises transferring heat to the rest of

00:56

the water but eating soup with liquid spoon probably wouldn't

00:59

work Out too well for us so we can next

01:02

be radiation is the transfer of heat by electromagnetic waves

01:07

If you put your hand near a hot light bulb

01:09

you'll feel heat This sensation comes from infrared waves created

01:12

by the heated likeable Last time we checked our soup

01:15

was not electromagnetic No If it were we might be

01:18

the next superhero or a super shmoop superman Something like

01:22

that's got a nice ring to it Evaporation occurs when

01:24

molecules of water gather enough energy from collisions with other

01:27

water molecules that they were able to break free and

01:30

go into the air because they're getting energy from other

01:33

water molecules that water actually loses He won evaporation occurs

01:37

all the hot molecules are running away And since our

01:40

spoon isn't losing feed we know d isn't our answer

01:43

Anytime there's heat transfer from direct contact that's conduction and

01:47

since the spoon heats up because it's touching the suit

01:50

the correct answer is a all this talk about food

01:53

has us getting hungry I'm pursuit and potentially superpowers who 00:01:57.163 --> [endTime] knows
