  • I also learned that Bridges Freeze faster than roads Because they can't hold heat in [1]
  • Another reason Bridges Freeze before roads is Because they're usually made of steel and concrete [1]
  • Hello Wonderopolis do roads Freeze Because the metal gets cold and all that metal from the cars [1]
  • Bridges tend to Freeze more quickly than roads Because they can’t trap what [1]
  • I think that Bridges are cool Because they are like a Road over something like a river i love wonderopolis.org Because there are things cool on here [1]
  • Compared to a roadway a Bridge has more Surface area to exchange energy with the atmosphere and Thus will cool down to the air temperature quicker [2]
  • Because of those extra energy gains the roadway cools more slowly and doesn’t form ice as quickly as the Bridge [2]
  • Thanks for another great wow on a Wonder today wow girl we appreciate your enthusiasm for Wonderopolis - [1]
  • Bridges on the other hand are totally exposed to the frigid air Thus they cool faster [7]
  • However the iceberg has more heat energy Because it is packed with more molecules [4]
  • Ice how come the Surface of a Bridge is the first part of the Road to Freeze while the water under a Bridge is always the last water to free.. [7]
  • I Wonder why ice has to come before the Bridge do you know Wonderopolis i predict.. [1]
  • So while the roadway will cool down it does not cool as fast Because of the energy gains it gets from the warmer ground below [2]
  • Rain or snow therefore will Freeze and stick to the Bridge [3]
  • Why does new pavement on a Road almost always stop at Bridges and overpasses leaving the concrete Surface of the Bridge with an annoying bump .. [7]
