What are the heat transfer from a pot on a metal grill heated over a campfire?

You will have heat transfer to the pot by radiation from the hot coals and by a combination of conduction and convection as the hot gasses of the fire rise to the pot. You might also have some slight heating by conduction from the metal grill to the pot; the grill gets heated the same way as the pot by radiation and flames but may be slightly warmer than the pot since it is closer to the coals and lies between the flames and parts of the pot resting on it. The total heat transfer from the grill to the pot is probably minimal. We would hope that the contents of the pot get heated by the walls of the pot - by conduction and, if they are fluid, convection.

When the metal ball is heated can it go through the metal ring?
when the ball is heated, it will pass through the unheated ring.
When a metal powder is heated in open dish it turns black which metal is that?
The metal might be copper. When copper is heated, it reacts with oxygen in air forming copper oxide which is black in colour.
Name one metal which does not react with oxygen when heated?
Brooks metal ;)
What happens to the particles in a metal when the metal is heated?
When a metal bar is heated....the particles in the area of the metal bar that is hot start vibrating.. knocking into each other and passing the heat energy on to cooler particles. The cooler end that isn't heated still has a rise in temperature just not as much as the heated area because the heat has almost been diluted.
What is the heat transfer of metal?
conduction
When a metal rod is heated at one end what energy transfer takes place in the rod?
conduction
Will the volume of metal decrease if it is heated?
No, the volume of a metal increases as it is heated. It expands.
How does heat travel along a metal?
By conduction. This means that atoms of the metal become more energetic when heated, and they transfer this energy from atom to atom, so it travels along the bar from the hot end to the cooler end
Why a glass jar can be easily opened if the metal lid is heated?
because metal will expand when it has been heated up
When the metal ball is heated can it go through the metal ring?
when the ball is heated, it will pass through the unheated ring.
Why do train tracks expand?
Metal expands when it is heated. Since track is made of metal then it expands when it is heated by the sun.
How heat transfer by conduction?
the particles at the heated end in say a metal rod gain kinetic energy and therefore start to vibrate more. These heated particles then hit other less energetic (hot) particles and then the heat is passed on that way until the whole object is heated up.
What expands when heated?
metal is a solid that expands when heated also of course when liquids are heated and change state into a gas they expand but metal is cool because it expands before it changes state
What properties are needed for the metal grill?

When a metal powder is heated in open dish it turns black which metal is that?
The metal might be copper. When copper is heated, it reacts with oxygen in air forming copper oxide which is black in colour.

What is the metal screen at the front of the car called?
It is called a grill.
