Movement of heat by direct contact
Nettet11. des. 2011 · Figure 1: Conduction of heat through a solid. Conduction is the flow of heat through a material by direct molecular contact. This contact occurs within a material or through two materials in contact. It is the most important heat transport mode for solids; it is sometimes important for liquids, and it is occasionally important for gases. NettetBy Radiation. Which temperature is the freezing point of water on the Celsius scale? 0 degrees. The transfer of heat between two substances that are direct contact is called. Conduction. Thermal Energy. Measures the total energy of the particles in a substance. The transfer of heat by the movement of a fluid is called.
