i think first where do you get the wood from??? trees?? so that's chemical. Then a campfire is hot right?? so it's thermal. So chemical to thermal

∙ 15y agoHeat is merely (in this case) air molecules that have been excited and are bouncing into adjoining molecules. The hitting of these molecules causes friction, friction producing heat. When the molecule moves through the space ("air") it bounces into other molecules but with slightly less energy (the amount of energy lost is equal to the amount of heat that is produced in the friction).
As more molecules bounce into adjoining molecules away from the heat source, the amount of energy that they do so reduces slightly to a point where, at a distance from the campfire, where no effect of the heat is felt. The closer to the fire that you get, the more energy that the 'bouncing molecules' have, therefore more friction to your skin, therefore it feels warmer.

What is a good clinical example of using the principle of convection to transfer heat?
Heated, enclosed infant incubators.
What effect if any does this energy transfer have on the overall efficiency of the car engine?
As a "heat engine", a car engine must rid itself of heat to continue. Efficiency of the heat engine depends on the difference in temperature; therefore, as the temperature outside reaches the temperature inside, the engine stops.
By which mode of heat transfer heat is transferred in solids?
the process of transfer of heat energy in solids is known as conduction.. For more info-- the process of transfer of heat energy in liquids and gases is known as convection.. And the process of transfer of heat energy without any material medium is known as radiation..
What method of heat transfer is known as conduction?
No,the transfer of heat by the movement of heated fluid is called convection.
What is the heat transfer mechanism responsible for the daily wind cycle?
heat transfer through convection.
How do you transfer heat energy by curtain?
how to transfer heat energy by using curtains
The way heat reaches the moon?
Since the space between the moon and other objects is essentially a vacuum, the only feasible mode for heat transfer is by radiative heat transfer.
Can you explain the transfer of heat within a material?
The transfer of heat within a material, I don't know about. But I can help you with the transfer of heat from one material to another. Heat always moves from the warmer material to the colder one. It does this until it reaches equilibrium. this means when both objects have the same amount of heat energy.
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.
What method of heat transfer does not require a medium to travel why is it important?
radiant For one thing, it's how heat energy from the sun reaches us.
What method of heat transfer are you using when you boil water?
convection
What are some appliances that operate using heat transfer?
saw
Is the heat transferred from a hot zinc roof to a person below it a good example of heat transfer by radiation Explain?
Yes - this should be a good example of heat transfer by radiation. It is unlikely you will transfer heat by natural convection since the roof is above the person and any heated air will rise to the roof rather than sink from the roof down to the person. Air is a rather poor conductor of heat so any heat transfer by conduction from the roof down to the person will be very slow. In contrast to this, the tin roof, if hot enough will be a fairly good heat radiator - enough that it could be sensed by a person below, i.e. they will feel the radiant heat transfer.
What on earth in transfer printing?
transfer printing is where you colour a paper and transfer your pattern onto a piece of fabric using a heat press. :)
How do you prevent heat transfer from conduction?
By using solid thermal insulators.
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
How does a thermos reduce heat transfer using convection?
A thermos reduces does not reduce heat transfer using convection, it reduces heat transfer BY convection. This is because there is a vacuum between the container of the liquid and the outer shell off the thermos. This means that no fluid will go round the inside conducting heat one way or the other. Hope this helped
