A popular winter activity of many college students is "traying," or sliding down a snow-covered hill on a tray borrowed from the dining hall. If Joanne removes a 0.35 meter x 0.65 meter aluminum tray (α aluminum = 24 x 10-6 C°-1) from the 20°C dining hall to go traying outside in the brisk -8°C winter air, how much will the tray shrink when it is taken outside?

A styrofoam cooler (k = 0.030 W/(m-°C) has outside dimensions of 0.170 m x 0.250 m x 0.260 m, and an average thickness of 2.0 cm. How long will it take for 1.10 kg of ice at -5.0°C to melt (to water at 0°C) in the cooler if the outside temperature is 34.0°C? Assume that ice temperature increases linearly from -5.0°C to 0°C. Neglect any temperature change of the air in the cooler. Data: Specific heat of ice is 2050 J/(kg-K). Laten heat of fusion of water is 3.34×105 J/kg.
On a cold morning, the rear window defroster on a 2002 Pontiac Aztek supplies 240 Watts of power to clear 0.794 kg of frost (ice), initially at -5.00°C. If all of the energy supplied goes to clearing the ice from the rear window, how long will it take?
The height of the Washington Monument is measured to be 170 m on a day when its temperature is 35.0°C. What will the change in its height be on a day when its temperature falls to -4.5°C? Although the monument is made of limestone, take the thermal coefficient of expansion to be the same as for marble, which is 2.50 x 10-6/°C. (Be sure to include the appropriate sign with your answer.). Enter a number. length and temperature are always defined as final value minus the initial value. Therefore be sure to consider the cign quantities om
A cramming student warms 0.500 L of cold coffee in a Pyrex carafe. Full carafe of coffee at 20°F. How much coffee has spilled when the coffee and carafe reach 95°C? Given that the carafe is an isotropic solid, Pyrex has a linear thermal expansion coefficient of 3.3 x 10-6 K-1 and water (coffee) has 207 x 106 K-1.

To keep yourself warm in the winter, you heat a solid metal ball and place it on a stand in the center of your room. The ball has a radius of 17.0 cm and an emissivity of 0.830. If your room has a temperature of 15°C, what is the net power radiated by the ball initially, when the ball's temperature is 200°C?
