In convection, heat transfer occurs through the movement of fluid particles, such as air in this case. As the gas flame heats the air surrounding the potatoes, the hot air rises and carries the heat towards the potatoes. The skewer helps to conduct the heat from the air to the inner layers of the potatoes, cooking them evenly.

What heat transfer method does a candle use?
A candle uses conduction and convection to transfer heat. The heat from the flame is conducted through the wick to melt the wax, which then rises as liquid and is heated further through convection as it is drawn up the wick and vaporizes to fuel the flame.
How is heat transferred through a metal skewer?
Heat is transferred through a metal skewer by conduction. As one end of the skewer is placed in a heat source, such as a flame, the metal molecules closest to the heat source begin vibrating rapidly. This vibration is then passed along the skewer to the cooler end, transferring heat energy along the length of the skewer.
Why if your hand is held high above a burning candle does it feel heat?
Even though heat rises due to convection, the energy from the flame travels in all directions and can reach your hand even when it is held above the candle. The heat radiates outward from the flame, which is why you can feel the warmth even if your hand is not directly above the flame.
Why is heat conduction through a metal rod faster if the rod is pointed DOWN into a flame than when it is pointed UP into a flame?
Because heat travels "up." I disagree. Heat travels "up" in a fluid, because the molecules expand and become lighter and "float" upwards. But in a solid? How can that be? If you notice, the question is asking about a rod being pointed down into a FLAME versus up. As we all know, flames "point" up, not down. Therefore it is hottest at the tip of the flame. This should answer the question. If not...feel free to message me.
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).

Where does conduction radiation and convection occure?
Condction-- In the Iron Box or Kettle from flame to Pot bottom Convection-- Airconditioning the room .Cooling takes place by movement of the cooler particles. Radiation-- From Sun transfer of heat. Or from a Bonfire in cols places.

Is BBQ conduction convection or radiation?
BBQ involves all three types of heat transfer: conduction from direct contact with the grill, convection from circulating hot air around the food, and radiation from the heat source (charcoal, gas flame) emitting infrared radiation that cooks the food.
What kind of heat transfer is grilling over charcoal flame?
Grilling over a charcoal flame involves heat transfer primarily by conduction. The heat from the burning charcoal is transferred to the grill grate, and then from the grate to the food through direct contact. Convection and radiation also play a role in cooking food on a charcoal grill by circulating hot air and emitting infrared heat.
How can you describe roasting a hot dog but not using roast hot dog fire stick?
You put a wiener on a skewer and heat it evenly over a flame??
Energy flows from a Bunsen burner flame to the water because there there is a?
Energy flows from the Bunsen burner because heat is given off, creating a chemical reaction between the water and flame. This causes the water to heat up until the flame reaches 100 degrees and then the water boils (this is the waters boiling point).
How do you spell shishkabobs?
The variant spelling "shish-kabob" refers to the skewer food "shish kebab."
What is convection central heating?
Convection is a way to transfer heat. When something is heated, by flame, for example, the air right above the flame will expand [as substances expand when heated]. This expansion will cause it to have a greater volume. The air will have the same mass, so its density will decrease as density is mass over volume. Because its density decreases, it will rise. Once risen, it will do the opposite: lose the energy by cooling, decrease in volume, increasing the density, and fall back down.
