What kind of heat transfer is a marshmallow over a bonfire?
A marshmallow over a bonfire is a radiant heat transfer. The marshmallows are not in direct contact with the flame but are held very close to reduce burning.
Why if your hand is held high above a burning candle does it feel heat?
Air near the flame is heated and rises, thus reaching your hand. This is heat transfer by convection.
If you put a pot on the stove the pot becomes hot. The heat is transferred to the pot on the burner by radiation. Please select the best answer from the choices provided T F?
It depends on the size of the flame. If the flame is large enough so that it touches the bottom of the pot, the heat is transferred directly from the flame to the pot by conduction. A smaller flame will radiate heat to the pot but will also heat the air between the flame and the pot (by conduction) and the hot air will also transfer heat to the pot by conduction. Either way, heat moves from the bottom of the pot to the rest of the pot and the food inside by conduction.
What is the relationships of radation conduction and convection?
radiation is heat transfer through light (both visible and not). with a nuclear bomb, surrounding distant flammeables combust because of irradiated infrared energy. conduction is heat transfer through direct contact. a pot on the stove gets heated by the flame that touches it. convection is heat transfer through a medium (really really slow).
The transfer of heat by fluid?
The transfer of heat by fluid is convection.
Best charcoal grills?
The Weber kettle grill is the best brand. Direct or indirect heat could be applied in conjunction with the dome lid (resulting in evenly spread out heat for grilling).
Radiation is the type of heat roasts the marshmallows?
When roasting a marshmallow the transfer of heat from the flame to the marshmallow is radiation.Radiation is the transfer of heat through energy waves. It can actually be considered conduction as well if you place the marshmallow into the flame, since that is the direct transfer of heat.

What type of heat transfer is used when cooking on a barbecue grill?
A grill uses kinetic energy to cook food. The energy itself, however, can come from many different sources, such as charcoal, propane fuel, or even electric heating elements.
What is the difference between grilling and baking?
The difference is the way heat is introduced to the food. In baking a food in placed into a hot oven and either conventional heat (conduction) or convection (circulated heat by fan) is used. Baking is used for bread & cakes which often require a leavener to cause the dough/batter to raise. Grilling it direct heat from a source below the food item. In such as case barbecuing is grilling. Also restaurans have a "grill" that uses some sort of a flame source direct/indirect. Gilling is high heat that causes browning of the meat
Why are pans placed over a flame and not on the side of the flame?
Pans are placed over a flame and not on the side of the flame, because it is an energy transfer by direct contact called conduction. And as you can see, pans are usually made of metals, wherein metals are a good conductor of heat unlike wood, which is a poor conductor of heat.

When a metal pan is heated on the stove what is it?
All stove flames are hotter than you would expect any pan to normally be so there is a temperature gradient between the flame and the pan. Heat is transferred from the hot gasses of the flame to the pan by two mechanisms: convective heat transfer and radiant heat transfer. Note that the hotter the flame, the more significant the radiant heat transfer becomes.
What are the method to trasfer heat?
There are three types of heat transfer, one is conduction or heat transfer through solids, convection, which is heat transfer through liquids and the last is radiation which is heat transfer through gas medium
What is the American word for grilling?
Some refer to grilling as "grilling," while others refer to it as "barbecuing," even though they are not one and the same. Grilling involves smoke, high heat, and hot and fast cooking, whereas barbecuing involves low heat and slow cooking.
Why if your hand is held high above a burning candle does it feel heat?
Air near the flame is heated and rises, thus reaching your hand. This is heat transfer by convection.
Using A Chimney Starter With A Charcoal BBQ Grill?
Starting a charcoal BBQ grill is best done with a chimney starter. This is a metal cylinder that can be filled with charcoal and then ignited from the bottom. The heat passes up through the chimney and ignites all of the charcoal evenly. The chimney is then emptied into the BBQ grill when it is hot enough. This prevents hotspots from forming in the grill and gives the person grilling better control when distributing the coals for multi-zone barbecuing.
