It is conduction, heat transfer where 2 objects touch, because the waffle iron and the waffle are touching.
(and it can't be radiation or convection.)
Kinetic and Electrical
Electical and thermal/heat energy
electricity.
This type of heat transfer is called conduction. The transfer is from the warm hand to cool water.
Sure.
convection Du!!!!!!!!!!!! .......
Energy transfer by convection is primarily restricted to fluids. One of the significant modes of heat transfer is convective heat transfer.
irstly from Thermodynamics point of view, we need to call heat as Heat transfer. Both Heat and work transfer are energies in transit. They come into picture only when a process is taking place. Also the quantity of heat transfer depends on the type of process or path followed. So Heat Transfer is a path function but not a property(which is a point function). 📷 In case of properties, the difference in properties (here P2-P1 or V2- V1)between state 1 and state 2 always remains same irrespective of the path followed. So properties are called Exact Differentials or Point functions. But in case of Heat transfer and Work transfer, the quantity of heat and work transfer between state 1 and state 2 depends on the path followed. Therefore heat and work transfer are not exact differentials,they are Inexact differentials or path functions.

How a particular waffle maker is used depends on the particular type of waffle maker in question. Stove-top waffle irons are heated over a burner (generally on a woodstove,) then oiled before batter is poured onto the hot surface. The waffle iron is closed, then turned over after several minutes so that both sides of the waffle are cooked evenly. The iron is then opened, the baked waffle removed, then the iron is brushed with oil again and another waffle baked in the same way. > Electric waffle irons are used on a table or countertop, and heated by electric coils beneath both the bottom and top irons. Most modern electric waffle irons regulate the heat to the correct temperature for light, medium or well-done waffles, and have lights or some other indicator that alerts the cook when the iron is ready. When the iron is hot, it may be brushed with oil. This step is unnecessary if the iron has a non-stick finish. Waffle batter is poured onto the pre-heated surface, the iron is closed, then the waffle removed when the indicator signals that the waffle is ready. Turning the iron is also unnecessary because both sides of the waffle are baked at the same time.
It is heat transfer by radiation.
No, in the universe radiation heat transfer is by far the largest transfer.
According to my research, a waffle iron of this type will run anywhere from $20 to $50. The median price was around $35.
Conduction
Radiation
Whether convection is the main type of heat transfer or not depends on the specific situation.
It is radiation, as that is the only heat transfer that can occur in a vacuum (the universe).
if you mean the transfer rate of heat ?; the heat transfer rate depends on the atom or molecule type .
