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.
Conduction
Because transfer of heat requires particles, so solid objects will be better at conducting heat than gas.

Convection is one of the major modes of Heat_transferand Mass_transfer. Convective heat and mass transfer take place through both Diffusionand by Advection, in which matter or heat is transported by the larger-scale motion of currents in the fluid.Convection is faster than conduction. In conduction, transfer of heat occurs by vibration of molecules in a fixed place. Convection, however, occurs by actual movement of molecules facilitating transfer of heat.
A vacuum motor can generate heat, which is transferred through radiating patterns, mostly.answer 2 heat can transfer by conduction, radiation, and convection (a special case of conduction).Heat can travel through a vacuum by radiation. I hope the sun felt warm at your place today.
Wrong, transfer of heat by conduction does take place in fluids.
In all circumstances where a material is hotter than its surroundings, heat transfer takes place.
Wrong, transfer of heat does take place in fluids. In fact it can take place more efficiently in fluids than in solids because convection is possible in fluids.
convection
Conduction
It is the process of transfer of heat from one place to other with actual movement of heated particles. Convention of heat take place in fluids and gases .

Its conduction I dont know more sorry but conductions one of them.
