Vedclass · Answer

(C) The primary mode of heat transfer in fluids (like air) is convection. When air near a fire is heated,it becomes less dense and rises due to buoyancy. This rising current of hot air carries a significant amount of heat upwards. Therefore,the temperature is much higher directly above the fire compared to the sides,where the air is not being actively replaced by the rising hot currents. Thus,option $C$ is correct.
