Correct Response: D. Conduction is the thermal-energy-transfer process that involves the transfer of kinetic energy between molecules as they collide. Radiation (A) is the thermal-energy-transfer process that involves the transfer of energy through electromagnetic waves. Latent heat (B) is not an energy- transfer process. It is the energy per unit mass absorbed or released by a substance during a change in phase. Convection (C) is the thermal-energy-transfer process that involves the transfer of energy through currents in fluids caused by variations in density due to uneven heating or cooling.
