An ice chest whose outer dimensions are 30 cm x 40 cm x 40 cm is made of 3-cm-thick Styrofoam (k = 0.033 W/m - °C). Initially, the chest is filled with 28 kg of ice at 0°C, and the inner surface temperature of the ice chest can be taken to be 0°C at all times. The heat of fusion of ice at 0°C is 333.7 kJ/kg, and the surrounding ambient air is at 25°C. Disregarding any heat transfer from the 40 cm x 40 cm base of the ice chest, determine how long it will take for the ice in the chest to melt %3D completely if the outer surfaces of the ice chest are at 8°C.

In an aluminum container weighing 0.30 kg are 0.70 kg of water in thermal equilibrium at a temperature of 70°C. Container and water temperature together cool at a rate of 2.5 K/min. What is the heat flux leaking from the container?
A sphere ( k=204 W/m K) with inner diameter 4 cm and outer diameter of 8 cm . The inside temperature is 100C and the outer temperature 50 C . Calculate the rate of heat transfer
1 kg aluminum dumbbell initially held 2 meters above the floor is allowed to fall. This experiment is performed inside a room whose dimensions are 10m— 5m— 3m. Assuming that thewalls of the room do not conduct heat and that the room is empty (no other objects are present besides the dumbbell itself), estimate the change of the temperature inside the room as a result as a result of dropping the dumbbell.
Consider a stainless steel spoon ( k = 8.7 Btu/hrft°F) partially immersed in boiling water at 200 deg * F in a kitchen at 75°F. The handle of the spoon has a cross section of 0.08in * 0.5in and extends 7 inches into the air from the free surface of the water. If the heat transfer coefficient at the exposed surfaces of the spoon handle is 3 Btu/hrft²°F, determine the temperature of the tip of the spoon handle. Assume that the heat loss from the tip of the spoon is negligible.
A 752-cm sample of water was placed in a 1.00-kg aluminum pan. The inital temperature of the pan was 26°C and the final temperature of the system was 39°C. What was the initial temperature of the water?
A student living in a 4 - m 5 - m 3 - m dormitory room turns on her 100 - W fan before she leaves the room on a summer day, hoping that the room will be cooler when she comes back in the evening. Assuming all the windows are tightly closed and disregarding any heat transfer through the walls and the windows, determine the temperature in the room when she comes back 8 h later. Use specific heat values at room temperature, and assume the room to be at 100 kPa and 20 ° C in the morning when she leaves.
