Heat Transfer A and D Statements
Statement
1. Cold and warm air mix together
and become medium-temperature
air.
_____ agree
_____ disagree
_____ it depends
My Thoughts
Statement
5. Radiation and convection cause
heat transfer without direct
contact.
_____ agree
_____ disagree
_____ it depends
2. Cold butter placed on hot corn
melts because of convection.
_____ agree
_____ disagree
_____ it depends
6. Water that sits in the shade will
be cooler than water that sits in
the sun.
_____ agree
_____ disagree
_____ it depends
3. Heat can be transferred between
objects by indirect contact.
_____ agree
_____ disagree
_____ it depends
7. When the bottoms of cookies
burn, but the tops do not, this is a
result of conduction.
_____ agree
_____ disagree
_____ it depends
4. When you walk on a hot sidewalk
and burn your bare feet, the heat is
transferred to your feet through
radiation.
_____ agree
_____ disagree
_____ it depends
8. Convection currents are caused
when cold water or air drops or
rises, opposite hot water or air.
_____ agree
_____ disagree
_____ it depends

1. Cold and warm air mix together
and become medium-temperature
air.
_____ agree
_x__ disagree
_____ it depends
My Thoughts
Cold air sinks, warm air rises,
creating convection currents.
Statement
5. Radiation and convection cause
heat transfer without direct
contact.
___x__ agree
_____ disagree
_____ it depends
My Thoughts
This is true. Objects do not need to
be touching to transfer heat
through radiation and convection.
2. Cold butter placed on hot corn
melts because of convection.
_____ agree
__x___ disagree
_____ it depends
Butter placed on hot corn melts
because it touches the hot corn.
Most of the heat is transferred
through conduction.
6. Water that sits in the shade will
be cooler than water that sits in
the sun.
_____ agree
_____ disagree
__x___ it depends
3. Heat can be transferred between
objects by indirect contact.
___x__ agree
_____ disagree
_____ it depends
Heat CAN be transferred through
indirect contact. Objects can give
off heat and heat something else
without touch another object by
radiating heat. Convection
currents transfer heat without two
objects touching, also.
7. When the bottoms of cookies
burn, but the tops do not, this is a
result of conduction.
__x___ agree
_____ disagree
_____ it depends
This would usually be true, unless
the air temperature in the sunlight
is cooler than the air temperature
in the shade. If two glasses of
water are in the same place, at the
same time, the shady place with
have a cooler temperature than
the sunny one because the sunny
place will absorb more heat
through radiation.
Heat is conducted to the cookie
dough through the metal cookie
sheet and can burn the bottoms of
the cookies faster than the heat
generated through convection
around the dough NOT touching
the cookie sheet.
4. When you walk on a hot sidewalk
and burn your bare feet, the heat is
transferred to your feet through
radiation.
_____ agree
__x___ disagree
_____ it depends
Because your feet are touching the
sidewalk, conduction is the main
source of heat transfer.
8. Convection currents are caused
when cold water or air drops or
rises, opposite hot water or air.
_____ agree
__x___ disagree
_____ it depends
Cold air or water will always drop.
Warm air or water will always rise.
That being said, convection
currents ARE the result of cold air
or water dropping and warm air or
water rising.
