This is something I have been thinking about since last night and I cannot figure it out!
The question is:
Explain how conduction causes the surface of a bridge to freeze sooner than the road surface on either side of the bridge.
The only thing that I can think of is that the air passing over and under the bridge creates a thermal energy transfer between the pavement and the air, cooling the bridge first rather than the road that doesn't have a space for the air to pass underneath it...but for some reason I don't think that's right.
Your thoughts?
