WebChapter 12: Radiation Heat Transfer Radiation differs from Conduction and Convection heat t transfer mechanisms, in the sense that it does not require the presence of a material medium to occur. Energy transfer by radiation occurs at the speed of light and suffers no attenuation in vacuum. Radiation can occur between two bodies separated by a ... WebAnswer (1 of 6): Yes, Radiators are simply high thermal conductivity metal in contact with air if the air is higher temperature that the metal heat will transfer by conduction, if the air is moving, heat will transfer by convection until the temperature of both have equalized. A condenser coil is...
