3. A long cylinder of length L and cross section A consists of two halves connected in the middle. One half is made from copper while the other from steel. The two ends of the cylinder are maintained at constant but different temperatures, the steel end at 100°C while the copper end is at 0°C. Assuming no loss of heat through the cylindrical surface, find the temperature at the copper-steel joint in a steady state.

A cylindrical brass rod is 10.0 cm in length and 0.500 cmin radius at 25.0°C. How much force do you have to apply to each endof the rod to maintain its length when the temperature is decreased to13.0°C? Are the required forces tensile or compressive?
At 19.0°C an aluminum ring has an inner diameter of 6 cm, and a brass rod has a diameter of 6.090cm. Keeping the brass rod at 19.0°C,to what temperature must the aluminum ring be heated toallow the ring tojust slip over the brass rod? Final answer should be in F.
A picture window has dimensions of 1.34 m by 2.65 m and is made of glass 5.93 mm thick. On a winter day, the outside temperature is -20°C, while the inside temperature is a comfortable 19.5°C. At what rate is heat being lost through the window by conduction? kglass = 0.80 W/m.K Round your answer to 2 decimal places.
A steel ring of 3.000 cm inside diameter at 20°C is to be heated and slipped over a brass shaft measuring 3.002 cm in diameter at 20°C. After being heated to the desired temperature. the ring and shaft together are cooled by some means such as liquid air, at what temperature will the ring just slip off the shaft?
V 13. At 20.0°C, an aluminum ring has an inner diameter of QIC 5.000 0 cm and a brass rod has a diameter of 5.050 0 cm. (a) If only the ring is warmed, what temperature must it reach so that it will just slip over the rod? (b) What If? If both the ring and the rod are warmed together, what tem- perature must they both reach so that the ring barely slips over the rod? (c) Would this latter process work? Explain. Hint: Consult Table 19.2 in the next chapter.
mmh When resting, a person has a metabolic rate of about 3.0 × 10° joules per hour. The person is submerged neck-deep into a tub containing 1.2 × 10° kg of water at 21.00 °C. If the heat from the person goes only into the water, find the water temperature after half an hour. 47.
It is desired to just able to slip the 16.0 mm diameter glass marble through an aluminum washer. At 68.0 F, the inner diameter of the washer is 15.98 mm. To what temperature in Fahrenheit should the aluminum washer be heated for the marble just able to slip through. The marble remains at 68.0 F. aluminum = 2.3x10-50 C-1; and glass = 2.7x10-50 C-1.

Thank u! A copper rod has one end in ice at a temperature of O°C, the other in boiling water. The length and diameter of the rod are 1.80 m and 3.90 cm, respectively. At what rate in grams per hour does the ice melt? Assume no heat flows out the sides of the rod. Thermal conductivity of copper is 401 W/(m-K). Latent heat of fusion for water, Lf= 333.7 J/g. Water boils at 100°C
A large punch bowl holds 3.95 kg of lemonade (which is essentially just water) at 20.0 °C. A 0.0450-kg ice cube at 0 °Cis placed in the lemonade. What is the final temperature of the system, and how much ice (if any) remains when thesystem reaches equilibrium? Ignore any heat exchange with the bowl or the surroundings.
We often cut a watermelon in half and put it into the freezer to cool it quickly. Butusually we forget to check on it and end up having a watermelon with a frozen layeron the top. To avoid this potential problem a person wants to set the timer such thatit will go off when the temperature of the exposed surface of the watermelon dropsto 3°C. Consider a 25-cm-diameter spherical watermelon that is cut into two equalparts and put into a freezer at 212°C. Initially, the entire watermelon is at a uniformtemperature of 25°C, and the heat transfer coefficient on the surfaces is 22 W/m2·K.Assuming the watermelon to have the properties of water, determine how long itwill take for the center of the exposed cut surfaces of the watermelon to drop to 3°C.Answer: 46.7 min
