It depends on the medium of heat transfer. For solids, it is conduction heat transfer. For liquids and gases, it is convection heat transfer. for vacuum (no medium), it is radiation heat transfer.
it is ratio of the total heat transfer from the surface area associated with both the fins and exposed portion of the base to maximum heat transfer from same surface area (in ideal conditions we get maximum heat transfer)
steam is lost in the plant through variuos way. But generally it is through heat transfer to the product to be heated by the steam. Also heat transfer through the conducting passage.

Due to nuclear reaction in the sun it emits enormous heat ,and heat does not require any medium to transfer.
The fastest mode of transfer of heat is conduction, where heat is transferred through direct contact between molecules in a material.
Conduction is the fastest method of heat transfer to melt ice. Placing the ice in direct contact with a warmer surface will transfer heat to the ice more rapidly than using convection or radiation.
Conduction . . . depends on the properties of the material through which the heat is conductedConvection . . . depends on the physical movement of the material carrying the heat from level to levelRadiation . . . electromagnetic waves, moving from place to place at the speed of light.Looks like Radiation would transfer heat the fastest.
Heat travels fastest in solids because the particles are closer together and can transfer energy more efficiently through collisions. Liquids and gases have particles that are more spread out, leading to slower heat transfer.
Radiation is the fastest form of thermal energy transfer through a vacuum because it does not require a medium to propagate. Heat can be transferred through electromagnetic waves, such as light, without the need for particles to carry it.
Heat transfer is in three modes. Conduction, convection and radiation. In case of conduction, the speed of transfer depends on the conduction property of the material. In case of convection, the speed of transfer depends on the density of the liquid. In case of radiation, the speed of transfer of heat is at the speed of light in air medium and a little bit less in other denser medium.
Fabrics that are good conductors of heat, such as polyester and wool, tend to melt ice the fastest. This is because they can absorb and transfer heat more efficiently compared to fabrics that are poor conductors, like cotton.
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
RAM (Random Access Memory) storage devices typically has the fastest transfer rate.
The fastest method of thermal energy transfer through a gas would be heat conduction due to collisions between gas particles transferring kinetic energy. These collisions lead to a rapid spread of heat throughout the gas.
Convection heat transfer is the transfer of heat by the movement of a fluid.
For conductive and convective heat transfer, the rate of heat transfer is proportional to the the temperature difference; if you double the difference you will double the rate of heat transfer. For radiative heat transfer, the rate of heat transfer is proportional to the difference of the 4th powers of the absolute temperatures.
