A closed box is filled with dry ice at a temperature of -86.0 °C, while the outside temperature is 21.0 °C. The box is cubical, measuring 0.394 m on a side, and the thickness of the walls is 4.49 × 102 m. In one day, 3.76 × 106 J of heat is conducted through the six walls. Find the thermal conductivity of the material from which the box is made. Number Units

A machinist wishes to insert a copper rod with a diameter of 7 mm into a hole with a diameter of 6.992 mm. By how much would the machinist have to lower the temperature (in °C) of the rod to make it fit the hole?

When the indoor temperature of a house is 25°C and the outdoor temperature is -8°C, the inside and outside surfaces of the glass are measured to be 21.4°C and 18.1°C.  If the glass has an area of 3.06 m2 and a thickness of 6.23 mm, what is the rate of heat (in W) lost though the window [round your final answer to zero decimal places]? {kglass = 0.78 W/m∙K}

Problem 21. Newton's law of cooling states that the temperature of an object changes at a rate proportional to the difference between its temperature and that of its sur- roundings. Suppose that the temperature of a cup of coffee obeys Newton's law of cooling. The coffee has a temperature of 80°C when freshly poured, and 1 min later has cooled to 70°C, when the temperature outdoors is 0°C. (a) Write an initial value problem for this model. (b) Determine the time when the coffee reaches a temperature of 40°C. (Note: Begin the solution by stating your notation).

One rod is made from lead and another from quartz. The rods are heated and experience the same change in temperature. The change in length of each rod is the same. If the initial length of the lead rod is 0.14 m, what is the initial length of the quartz rod?

A machinist wishes to insert a copper rod with a diameter of 4 mm into a hole with a diameter of 3.995 mm. By how much would the machinist have to lower the temperature (in °C) of the rod to make it fit the hole?

Instructions: Provide the answer in standard scientific notation with SI units that do not have prefixes (except for kg). Provide final answer with correct units and 3 significant figures. Please avoid round off error

Newton's Law of Cooling  The temperature of a cup of coffee t min after it is poured is given by the following equation where T is measured in degrees Fahrenheit. T = 65 + 90e−0.068t   (a) What was the temperature (in degrees Fahrenheit) of the coffee when it was poured? ____ °F (b) When (in minutes) will the coffee be cool enough to drink (say, 120°F)? (Round your answer to one decimal place.)  ______min
