Answer:
From the object at higher temperature to the object at lower temperature
Step-by-step explanation:
Heat corresponds to the transfer of thermal energy between two objects. Temperature gives a measure of "how much thermal energy an object has": the higher the temperature, the faster the molecules inside the object, the more thermal energy the object has. Therefore, an object at higher temperature has more thermal energy than an object at lower temperature, so the transfer of heat goes from the object at higher temperature to the object at lower temperature.
