Question 304General Subjects - Assistant Engineer

The correct answer is B) Convection. Convection is the mode of heat transfer associated with the transport of thermal energy from one location to another by fluid in motion. In convection, heat is transferred by the movement of a fluid, such as air or water, which carries the thermal energy with it as it flows. This is in contrast to conduction, where heat is transferred through direct contact between stationary materials, or radiation, where heat is transferred through electromagnetic waves. The other answer choices are incorrect because they do not represent the mode of heat transfer described in the question. Sublimation is the transition of a substance directly from the solid to the gaseous state, and radiation is the transfer of heat through electromagnetic waves, not fluid motion.
