If heat is being transferred by conduction, separating the two objects will stop heat transfer by that means.
If heat transfer is by convection, stopping the flow of fluid between two objects will eliminate that means of heat transfer. One notable way of doing that is to interpose a vacuum between the two objects.
If heat transfer is by radiation, the energy has to be sent out by the source and absorbed by the sink without interruption. If that can be interrupted then that can't happen. Some ways of achieving this are
- place a non-transparent barrier between the source and sink - of course if the barrier absorbs the heat and then re-radiates it out the other side you still have heat transfer
- make the surface of the sink perfectly reflective - in which case no energy would be absorbed and thus no heat transfer would occur. Note that getting perfect reflectivity is impossible as far as we know.
- separate the source and the sink an infinite distance such that attenuation of the transmitted energy would reduce it to zero. Of course we don't have infinite distance to work with so that will only work for a thought experiment.
Of course in all cases if the temperatures of two objects are the same, no heat transfer will occur no matter what mode of heat transfer you are considering.

What is a simple definition of thermal insulation?
An insulator is something that keeps heat in, for example, if you put a piece of fake fur around a mug of hot chocolate, it would act as an insulator, and would keep the heat in the mug. x if u eant insulator..then it means a poor heat conducto, or poor conductor of electricity ----------------------------------------------------------------------------------------------------------------------------------------------------- Materials that do not easily give up or take on electrons are called insulators.
The transfer of heat by fluid?
The transfer of heat by fluid is convection.
Is convection the main type of heat transfer?
No, in the universe radiation heat transfer is by far the largest transfer.
Is conduction a heat transfer by direct contact of particles of matter?
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).
What is the difference between heat transfer and mass transfer?
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.
Does the transfer of heat stops in two bodies in contact when they attain the same temperature?
YES.

A good conductor of heat?
A good conductor of heat is one that is able to transfer heat. Most metals are good conductors of heat and are often used in heating processes.
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
What are two examples of heat transfer?
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
What is convective heat?
Convection heat transfer is the transfer of heat by the movement of a fluid.
How does temperature affect the rate of heat transfer?
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?
The transfer of heat by fluid is convection.
What do conduction and convection have in common?
They're both modes of heat transfer via material media.
Winds transfer heat energy by what method of heat transfer?
convection
How heat transfer is controlled?
There is a special mechanism that controls heat transfer.
Is convection the main type of heat transfer?
No, in the universe radiation heat transfer is by far the largest transfer.
