Heat flows from the cool surface to the hot object.
Heat flows from the hot object to the cool surface.
Heat flows in both directions, between both surfaces.
Heat does not flow between the object and the surface.

Answer 1

b) heat flows from the hot object to the cool surface.

Step-by-step explanation:

This is because of thermal conductivity:

Heat travels into cooler objects until the temperature is even, but as it does so, the cooler object cools down the hot object and the hot heats the cool.
