Until the objects touching have equal temperatures.
Heat flow's from cooler objects.
Apparently No, heat flow in oceanic crust is higher than continental crust
No, heat energy does not flow indefinitely. It will continue to flow until a thermal equilibrium is reached where all objects involved reach the same temperature. Once this equilibrium is achieved, there will be no further flow of heat energy.
negative heat
Yes, no problem, as long as there is sufficient air flow behind them to dissipate the heat.
Heat flow is made by conduction, convection or radiation.
heat flow and waves
Yes, heat can never flow from a colder object to a hotter object, as stated by the principle that heat can never flow from a lower temperature to a higher temperature.
Interatomic separation causes heat to flow slowly. As there will be time involved in transferring heat at a gap.
In most realistic situations heat flow can be said to occur from a region of higher temperature to one of lower temperature. As the region of higher temperature loses heat and the other region gains heat their temperatures become closer and the rate of heat flow diminishes. If, however, it can be contrived to maintain the source of heat at a constant temperature and the destination of the heat also at a constant temperature, then the heat will flow between the two at a constant rate, called steady heat flow.
False... The flow of heat through direct contact is conduction.
The solid layer of the Earth that can flow due to great heat and pressure is the asthenosphere. It is located beneath the lithosphere and is partially molten, allowing it to deform and flow over long periods of time. This flowing movement of the asthenosphere is responsible for the movement of tectonic plates.
