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 type of heat transfer does fibreglass insulation in a dishwasher mainly stop?
Fiberglass insulation in a dishwasher mainly stops heat transfer through conduction. It helps to trap heat inside the dishwasher, preventing it from escaping to the surrounding environment.
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.
When does heat stop flowing between two objects?
Heat flow between two objects stops when they reach thermal equilibrium, meaning they have the same temperature and there is no longer a temperature difference to drive heat transfer. At this point, the heat transfer between the objects ceases.
When does heat stop transferring during conduction?
Heat transfer stops during conduction when the temperature difference between the two materials in contact becomes zero. At that point, thermal equilibrium is reached, and there is no longer a temperature gradient to drive heat transfer.
When does heat energy stop transferring?
Heat energy stops transferring when two objects in contact reach thermal equilibrium, meaning they are at the same temperature. At this point, there is no temperature difference to drive further heat transfer.
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 are two examples of heat transfer?
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
How will heat stop moving?
Heat can stop moving through a process called thermal equilibrium. This occurs when objects reach the same temperature and there is no more transfer of heat between them. In this state, the heat distribution becomes stable, and the movement of heat stops.
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.
What is the convective heat transfer coefficient of water and how does it impact the rate of heat transfer in a system?
The convective heat transfer coefficient of water is a measure of how easily heat can move through water. A higher convective heat transfer coefficient means heat can transfer more quickly. In a system, a higher convective heat transfer coefficient can increase the rate of heat transfer, making the system more efficient at exchanging heat.
