Detailed explanation-1: -Detailed Solution. Ultraviolet radiation is not a method of heat transfer. While cooking, heat transfer occurs only through conduction, convection, or radiation.
Detailed explanation-2: -Heat conduction, also called diffusion, is the direct microscopic exchanges of kinetic energy of particles (such as molecules) or quasiparticles (such as lattice waves) through the boundary between two systems.
Detailed explanation-3: -Various heat transfer mechanisms exist, including convection, conduction, thermal radiation, and evaporative cooling.
Detailed explanation-4: -Without this difference, no heat transfer can take place. Heat can be transferred in three ways: by conduction, by convection, and by radiation.
Detailed explanation-5: -Answer and Explanation: The correct answer to the given option is d. Mass is not considered a form of energy transfer.
