Heat conduction occurs when heat flows through a ______ material or between objects in direct contact, without the bulk motion of the material itself. In this process, heat is transferred from regions of ______ temperature to regions of lower temperature, following the temperature ______ of the material. The rate of heat conduction is determined by the ______ conductivity of the material, which quantifies its ability to conduct heat. Materials with high thermal conductivity, such as metals, conduct heat ______ materials with low thermal conductivity, such as plastics or wood. By optimizing materials and designs to enhance heat conduction, engineers can improve the efficiency and performance of ______ systems and devices.
