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
Full Transcript
- 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
