Answer #1:
Heat transfers from a barbecue grill to your Hamburgers mostly by convection.
Heat tends to rise and the hamburgers are above the fire. There may also be
heat in the form of radiation, and the transfer of heat by direct contact with the
fire (conduction).

Answer #2:
Heat transfers from a barbecue grill to your hamburgers mostly by radiation.
When you say "Heat tends to rise ...", what you really mean is that a pocket of
hot fluid surrounded by a colder bunch of the same fluid will rise through the
fluid. That's certainly true of the air in the barbie, but the amount of heat that air
can carry is relatively small in that situation. If you had to wait around for the
burgers to cook by convection, your guests would be sending out for Pizza long
before the beef was ready.

Is the heat transfer from a barbecue fire to a person standing in front of it a good example of heat transfer by conduction?
No. Not unless the person touches the BBQ. More a case of heat radiation.

No. Not unless the person touches the BBQ. More a case of heat radiation.
The transfer of heat by fluid?
The transfer of heat by fluid is convection.
Is convection the main type of heat transfer?
No, in the universe radiation heat transfer is by far the largest transfer.
Is conduction a heat transfer by direct contact of particles of matter?
Yes, whereas convection heat transfer is the transfer of heat via a liquid, and radiative heat transfer occurs through empty space (like the heat you feel from the sun).

What is the meaning of barbecue lunch or dinner?
a barbeque is chocolate cuverd burgers
What do Australians eat on the barbecue?
Sausages, burgers, steak, chicken, seafood, some sweet food dishes
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
What are two examples of heat transfer?
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
What is the specific heat of barbecue sauce?
Room temperature.
How does temperature affect the rate of heat transfer?
For conductive and convective heat transfer, the rate of heat transfer is proportional to the the temperature difference; if you double the difference you will double the rate of heat transfer. For radiative heat transfer, the rate of heat transfer is proportional to the difference of the 4th powers of the absolute temperatures.
What is convective heat?
Convection heat transfer is the transfer of heat by the movement of a fluid.
The transfer of heat by fluid?
The transfer of heat by fluid is convection.
What do conduction and convection have in common?
They're both modes of heat transfer via material media.
Winds transfer heat energy by what method of heat transfer?
convection
