Less heat is carried away from the feet.
A confluence of conduction and stupidity.
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.
Air near the flame is heated and rises, thus reaching your hand. This is heat transfer by convection.
When you burn your finger, it most often happens when you touch somethinghot, and the heat transfers to the skin by conduction.A much better example of burning yourself by radiation is sunburn.
Heat sink, insulative value of air, density of substances & heat transfer.
yes,because heat has a high temperature
The energy transfer is: chemical --> light and heat the heat is the waste product
This depends on the source of heat, and whether it is tangible or not. The composition of the window can also determine the nature and rate of heat transference. If the house is burning down and you've got wooden windows, heat transfer will normally be caused by the flames burning the wood.

heat energy conversion in generation of electricity..i.e..burning of coal..
Usually through the animal's feet. An animal lying on the rock may transfer heat to the rock according to the latent heat of animalization.
A 200,000 BTU wood burning stove will heat 1,000 square feet.
On an electric stove, the heat coil directly touches the pot, facilitating the conduction or direct heat transfer. On a gas stove, the burning fuel transfers heat to a pot by both radiation and convection.

yes convection is way of heat transfer. example : in boilers evaporators are heated up with exhaust gases of coal burning., smoking cigareetes have convective heat transfer to mouth.
