The steel bed suspension bridge is 200 m long at 200 C. If the extremes of temperature to which it might be exposed are -300 C to +400 C, what is the total range the expansion joints must accommodate for? The coefficient of linear expansion for steel is 12×10-6 (C0)-1.

A gas expands from I to F in the figure below. The energy added to the gas by heat is 406 J when the gas goes from I to F along the diagonal path. (a) What is the change in internal energy of the gas? (b) How much energy must be added to the gas by heat for the indirect path IAF to give the same change in internal energy?
