Heat transfer to cups (or other solid objects) happens on a molecular level; fast moving hot molecules (perhaps in your hot coffee) collide with slower moving cold molecules (in your cup) and speed them up, giving up some of their own momentum.
The transfer of heat by fluid is convection.
No, in the universe radiation heat transfer is by far the largest transfer.
Yes, whereas convection heat transfer is the transfer of heat via a liquid, and radiative heat transfer occurs through empty space (like the heat you feel from the sun).
Heat transfer deals with the movement of heat and temperature gradients. The three types of heat transfer are conduction, convection, and radiation. Mass transfer deals with concentrations of a particular substance. Types of mass transfer include diffusion and convection.
Insulation will reduce heat transfer.
Convection heat transfer is the transfer of heat by the movement of a fluid.
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
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.
The transfer of heat by fluid is convection.
They're both modes of heat transfer via material media.

There is a special mechanism that controls heat transfer.
No, in the universe radiation heat transfer is by far the largest transfer.
Yes, whereas convection heat transfer is the transfer of heat via a liquid, and radiative heat transfer occurs through empty space (like the heat you feel from the sun).
Radiation in heat transfer is one of three known modes of heat transfer: conduction (as heat transfer in solids and less effective in liquids)), Convection (as in liquids and gases), and radiation (that not necessarily require a medium for the transfer). Heat of sun is transferred to us in the vacuum space by radiation heat transfer.
