Equal 0.400-kg masses of lead and tin at 60.0C are placed in 1.00 kg of water at 20.0C. (a) What is the equilibrium temperature of the system? (b) If an alloy is half lead and half tin by mass, what specific heat would you anticipate for the alloy? (c) How many atoms of tin NSn, are in 0.400 kg of tin, and how many atoms of lead NPb are in 0.400 kg of lead? (d) Divide the number NSn of tin atoms by the number NPb of lead atoms and compare this ratio with the specific heat of tin divided by the specific beat of lead. What conclusion can be drawn?
(a) Calculate the rate of heat conduction through a double-paned window that has a 150-m2 area and is made of two panes of 0.800 cm-thick glass separated by a 1.00 cm air gap. The inside surface temperature is 15.0 C, while that on the outside is 10.0 OC. (Hint: There are identical temperature drops across the two glass panes. First find these and then the temperature drop across the air gap. This problem ignores the increased heat transfer in the air gap due to convection.) (b) Calculate the rate of heat conduction through a 1.60-cm-thick window of the same area and with the same temperatures. Compare your answer with that for part (a).
A high-pressure gas cylinder contains 50.0 L of toxic gas at a pressure of 14107 N/m2 and a temperature of 25.0 . The cylinder is cooled to dry ice temperature ( 78.5 ) to reduce the leak rate and pressure so that it can be safely repaired. (a) What is the final pressure in the tank, assuming a negligible amount of gas leaks while being cooled and that there is no phase change? (b) What is the final pressure if one-tenth of the gas escapes? (c) To what temperature must the tank be cooled to reduce the pressure to 1.00 atm (assuming the gas does not change phase and that there is no leakage during cooling)? (d) Does cooling the tank as in part (c) appear to be a practical solution?
A hollow aluminum cylinder 20.0 cm deep has an internal capacity of 2.000 L at 20.0C. It is completely filled with turpentine at 20.0C. The turpentine and the aluminum cylinder are then slowly warmed together to 80.0C. (a) How much turpentine overflows? (b) What is the volume of the turpentine remaining in the cylinder at 80.0C? (c) If the combination with this amount of turpentine is then cooled back to 20.0C, how far below the cylinders rim does the turpentines surface recede?
Consider an object with any one of the shapes displayed in Table 10.2.

Assume the average linear expansion coefficients shown in Table 16.1 do not vary between 0C and 100C. (c) Why are the answers for parts (a) and (b) the same for all the shapes?

= As shown in the figure below, you have a system including a Iron cup with mass Mcup = 0.214 kg. The cup contains water with mass Mwater = 0.345 kg. Both the cup and water are initially at a temperature of 31.8 degrees Celsius. You drop ice into the system. The ice has an initial temperature of -51.0 degrees Celsius and a mass of Mice 1.1490 kg. The system will reach equilibrium with none the ice having melted, but some of the water having frozen at the final temperature of 0 degrees Celsius. ice ice Beryllium Cadmium Iron Lead water cup Find the mass of water frozen, mfrozen = Material c (J/(kg K)) Aluminum 897 1820 231 412 129 2303 466 116 ice Polyethylene Steel Uranium None of the ice melts.
