Answer:
1. Yes, Because heat will always transfer from the warmer object to the colder object. The heat transfer will stop when the two objects are at the same temperature and reach thermal equilibrium.
2. The direction of heat flow in a small element within a solid only depends on the temperature of its neighboring elements. Heat within the solid will flow from hot to cold. It will cheerfully flow downward if it is cooler down there.
3. Yes, Because heat always flows from a hot place to a cold place when flowing spontaneously, but you can force heat to flow the opposite way by using energy, like in a refrigerator. Heat will continue to flow until the two objects reach the same temperature, which is called thermal equilibrium.
