ARadiation
BConduction
CSublimation
DConvection
AI Explanation
The correct answer is B) Conduction. Conduction is the mode of heat transfer that is associated with the transport of thermal energy within a body or between two bodies in direct contact. This is because in conduction, heat is transferred through the vibration of atoms or molecules within a material, or between materials in direct physical contact, without the involvement of any bulk motion of the material. The other options are incorrect because: A) Radiation involves the transfer of heat through electromagnetic waves, C) Sublimation is a phase change process, and D) Convection involves the transfer of heat through the bulk motion of a fluid.
