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.

How is heat transferred through kettle walls.'?
Heat is transferred through kettle walls primarily by conduction. When the kettle is heated on a stove, the heat from the flame is transferred to the bottom of the kettle through conduction. This heat is then transferred to the rest of the kettle through the metal walls by conduction as well.
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.
When I put my palm side of a candle how was the heat transferred to my palm?
The heat from the candle is transferred to your palm primarily through conduction. Conduction is the transfer of heat through direct contact between two objects at different temperatures. In this case, the heat is conducted from the candle's flame to your palm as they come into contact with each other.
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.
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).

Is a pan over a flame radiation or conduction?
Both the flame heating the pan and the pan heating the water are examples of conduction. Convection is when the molecules of water heat other molecules of water.

Holding your hand 30 centimeters above the flame of a candle you will receive the most heat by means of?
Conduction - the heat from the flame will be transferred directly to your hand through physical contact.
When water is in a pan over a flame why does the water get hot?
When water is in a pan over a flame, the heat from the flame is transferred to the water through conduction. As the water molecules gain energy, they move faster, which causes the overall temperature of the water to increase. This process continues until the water reaches its boiling point and starts to evaporate.
Why does the water boil in container when the utensil is placed on a flame?
due to conduction
Why does a blue flame make more noise than a yellow flame on a Bunsen burner?
Your not hearing the flame your hearing the gas move through the burner. and it is louder because it takes more gas moving through (so gas moving faster) than it does for a flame that is not as hot.

What are grilling hamburgers over a charcoal flame of which heat transfer?
Grilling hamburgers over a charcoal flame involves heat transfer by conduction. The heat from the charcoal is transferred to the grates of the grill, and then to the burgers through direct contact, cooking them evenly and creating a delicious sear on the outside.
What Example of Conduction heat?
-ice in a drink - flat iron
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.
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).
