Question

If two objects have different temperatures, in which direction will heat move? When will the heat stop moving?

Answer 1

Answer: When there are two objects of different temps, the heat will always move from the higher temp to the lower temp. The energy will stop moving when there is equilibrium, when both objects are at the same temperatures.

Answer 2

When you bring two objects of different temperature together, energy will always be transferred from the hotter to the cooler object. The objects will exchange thermal energy, until thermal equilibrium is reached, i.e. until their temperatures are equal. We say that heat flows from the hotter to the cooler object.
