Hakeem has two objects that are different temperatures. The beginning temperature of object A is 10°C. The beginning temperature of object B is 29°C. He places the two objects so that they are in contact with each other. Which diagram accurately shows the direction of heat flow in this scenario?
None of the diagrams you attached shows the scenario accurately,
or at all.
Heat flows from Object-B to Object-A, until both objects are at
the same temperature, somewhere between 10°C and 29°C.
