The transfer of energy caused by a temperature difference is called?

The transfer of energy that occurs due to a temperature difference is referred to as heat. This process is fundamental in thermodynamics and is characterized by the flow of thermal energy from a region of higher temperature to a region of lower temperature. Heat transfer can occur through conduction, convection, or radiation, depending on the circumstances and the materials involved.

This definition and understanding of heat set it apart from other concepts in thermodynamics. For example, work refers to energy transfer that results from a force acting through a distance, which does not necessarily rely on a temperature difference. Pressure is a measure of force per unit area and does not directly relate to energy transfer in the context of temperature variations. Volume pertains to the amount of space occupied by a substance and does not encompass energy transfer phenomena.

Thus, the correct identification of heat as the energy transfer mechanism linked to temperature differences is a crucial aspect of thermodynamics and plays a significant role in understanding thermal processes.
