Bob built a scale model of the bridge that is 2.637m long at the lowest temperature (T=-45 degrees Celsius) using an unknown material. When the temperature reaches the highest value (T=43 degrees Celsius), he measures again the length of the bridge finding that it has expanded L=5.56mm. Calculate the coefficient of linear expansion and find the material Bob used to make his model.

A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a. If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.
