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.
Bridges get their name by the kind of bridge they are
No
it doesnt
no se
A change in temperature of the core would probably have to be rather large to be noticeable, however it would affect plate tectonics. Lowering the temperature of the core would slow down activity and raising it would increase.
Ambient temperature might affect the readings of the resistance value you would measure because the resistance of some materials changes with the temperature.
Temperature has no effect on molar mass
Doubles it
the factor that will affect it is temperature.

Tornadoes have caused bridges to collapse on a number of occasions. In some cases pieces of bridges have been carried away by tornadoes.
Torsion, compression, and tension
