Question 13Safety & Environmental - QMED

The correct answer is D) convection. The spreading of fire through a vessel's ventilation system is an example of heat transfer by convection. Convection is the transfer of heat through the movement of a fluid, such as air or water, which can carry heat from one location to another. In the case of a fire on a vessel, the hot air and gases produced by the fire can be circulated through the ventilation system, spreading the fire to other areas of the vessel. The other answer choices are incorrect because: A) Conduction involves the direct transfer of heat through a solid material, which is not the primary mechanism by which fire spreads through a vessel's ventilation system. B) Radiation refers to the transfer of heat through electromagnetic waves, which is not the main mode of heat transfer in this scenario. C) Windage is the force exerted on a vessel by the wind, which is not directly related to the heat transfer process in this case.
