the metal or concrete might expand if it gets too hot and compress when it gets too cold.
by contracting and expanding
An increase in temperature will reduce the density, reduce the viscosity, reduce thermal conductivity, and increase the specific heat capacity. A decrease in temperature will have the opposite affect.
If you are asking if a hot wire has a greater resistance than a cold wire then the answer I would say is yes. Cold wires have always had less resistance than hot wires
arch bridges can support more weight than beam bridges but for price i say beam won.
Abon Bridges
No
it doesnt
no se
Ambient temperature might affect the readings of the resistance value you would measure because the resistance of some materials changes with the temperature.
Doubles it
the factor that will affect it is temperature.
Bridges freeze at the same temperature as roads and other surfaces, typically around 32 degrees Fahrenheit (0 degrees Celsius).
Tornadoes have caused bridges to collapse on a number of occasions. In some cases pieces of bridges have been carried away by tornadoes.

It makes them fall.
An incorrect reading of temperature would not directly affect the molar mass of a substance. Molar mass is a fixed property of a substance regardless of the temperature at which it is measured. Temperature typically affects the physical state and behavior of the substance, but not its molar mass.
Thermal expansion means that the length of the bridge changes.
