If 54 J of heat is added to an aluminum can with a mass of 29.5 g , what is its temperature change? Specific heat capacity of aluminum is 0.903 J/g∘C.
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 heat conducting rod, is made of an aluminum section that is 0.10 m long, and a copper section that is 0.80 m long. Both sections have cross-sectional areas of 0,0004 m2. The aluminum end is maintained at a temperature of 20°C and the copper end is at 121°C. The thermal conductivity of aluminum is 205 W/m∙K and of copper is 385 W/m∙K. Steady state has been reached, and no heat is lost through the well-insulated sides of the rod....
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 rod made of iron with a mass of 0.90 kg is heated to 800°C, then dropped into 7.00 kg of water at 10°C.
