Final answer:
Heat moves from an area of higher temperature to an area of lower temperature, a fundamental concept in thermodynamics related to the transfer of thermal energy.
Step-by-step explanation:
Heat transfers from an area of higher temperature to an area of lower temperature. This is a fundamental concept in thermodynamics, describing the flow of thermal energy between two systems or substances when there is a temperature difference. The rate of heat transfer is influenced by the temperature gradient, the materials involved, and other factors like convection and radiation.
In the context of diffusion, substances move from an area of higher concentration to an area of lower concentration, which is an analogous process. However, heat transfer explicitly refers to thermal energy, not substance concentration, moving due to temperature differences.
