Final answer:
Heat flows from objects with higher temperature to objects with lower temperature because it is the transfer of thermal energy.
Step-by-step explanation:
The incorrect statement is: Heat flows from a substance of higher temperature to a substance with a cooler temperature.
Heat always flows from objects with higher temperature to objects with lower temperature because heat is the transfer of thermal energy from a warmer object to a cooler object.
For example, when you touch an object, such as a hot stove, the heat from the stove transfers to your hand, making it feel hot. This is because the stove has a higher temperature than your hand.
