An aluminum rod with a diameter of 2.5 cm and a length of 40 cm is held between two heat reservoirs. The colder reservoir is at 15°C. The thermal conductivity of aluminum (kT) is 238 W/mC° and 32 Watts of heat energy are flowing along the length of the rod due to conduction. What is the temperature of the other reservoir?
A rod made of cobalt with a mass of 0.80 kg is heated to 850°C, then dropped into 7.00 kg of water at 10°C. What is the total change in entropy (in J/K) of the rod-water system, assuming no energy is lost by heat from this system to the surroundings? The specific heat of cobalt is 420 J/(kg · K), and the specific heat of water is 4,186 J/(kg · K). (Hint: note that dQ = mcdT.)

A straight rod consists of of 0.82 cm long piece of aluminum attached to a 2.84 cm long piece of steel. By how much will the length of this rod change if its temperature is increased from 11 degree celsiu to 28 degree celsius. The average coefficient of linear expansion of aluminum and steel is 2.5x10^-5 (celsius)^-1 and 1.2 x10^-5 (celsius)^-1 respectively.
A copper rod and an aluminum rod of equal diameter are joined end to end in good thermal contact. The temperature of the free end of the copper rod is held constant at 100°C, and that of the far end of the aluminum rod is held at 0°C. If the copper rod is 0.80 m long, what must be the length of the aluminum rod so that the temperature at the junction is 50°C?
