Wide-angle fog can cool a significantly ____________ surface compared to a steady stream.

The correct answer is larger because wide-angle fog is characterized by its ability to disperse moisture over a greater area. Unlike a steady stream that typically concentrates airflow or moisture in a focused trajectory, wide-angle fog creates a more extensive humid environment through which the cooling effects of evaporation can act upon a broader surface. This process allows for a larger surface area to be cooled as the fog interacts with it, making it effective for applications such as cooling down equipment or areas where heat buildup occurs. Other options do not align with the concept of the effect wide-angle fog has in terms of surface size and heat management.
