The flow of thermal energy is called heat transfer. It is through the various means of heat transfer that thermal energy moves from one place to another. Heat moves from where it is hot to where it is not. Always. Think it through and it will make perfect sense.
the flow of thermal energy
We call material that acts in that way a thermal insulator. Sometimes we shorten it to just insulation, but we need to be clear that we're talking about thermal energy and not, say, electrical energy.
yes or no ______________________________________ yes
heat
yes it is
Higher temperature to lower temperature. Thermal energy will always flow down the energy gradient.
When they are in thermal contact and their temperatures are the same there is no NET flow of energy. If the objects are both thermally insulated there will be no flow of energy at all.
yes or no ______________________________________ yes

It will flow to the cold substance
it doesnt i dont think.
Heat :)
