An aluminum rod 0.500 m in length and with a cross-sectional area of 2.50 cm2 is inserted into a thermally insulated vessel containing liquid helium at 4.20 K. The rod is initially at 300 K. (a) If one-half of the rod is inserted into the helium, how many liters of helium boil off by the time the inserted half cools to 4.20 K? Assume the upper half does not yet cool. (b) If the circular surface of the upper end of the rod is maintained at 300 K, what is the approximate boil-off rate of liquid helium in liters per second after the lower half has reached 4.20 K? (Aluminum has thermal conductivity of 3 100 W/m K at 4.20 K; ignore its temperature variation. The density of liquid helium is 125 kg/m3.)
In an experiment to determine the thermal conductivity of a new metal alloy, a bar of the metal is completely surrounded by insulation and exposed to 707 W of constant heat energy at one end. The bar has a radius of 0.074 m and a length of 0.331 m. The entire set-up is place in a cold room and once the system has reached steady state conditions, the temperature at the hot end is measured to be 63.8°C and the temperature at the cold end is measured to be 14.9°C. What is the thermal conductivity (in W/m∙K) of the metal alloy [round your final answer to zero decimal places]? Another metal alloy was tested using the same set-up (same size and heat input) as question above. If the temperature difference between the hot end and the cold end for this test was found to be 30°C, it would indicate that this material is a better conductor of heat than the material tested in question above.

A 1.0 m * 1.5 m double-pane window consists of two 4-mm-thick layers of glass (k = 0.78 W/m·K) that are separated by a 5-mm air gap (kair = 0.025 W/m·K). The heat flow through the air gap is assumed to be by conduction. The inside and outside air temperatures are 20°C and 220°C, respectively, and the inside and outside heat transfer coefficients are 40 and 20 W/m2·K. Determine (a) the daily rate of heat loss through the window in steady operation and (b) the temperature difference across the largest thermal resistance.
