A solid sphere with radius 3.50 cm is suspended within a large, evacuated enclosure whose walls are at 300.0 K. A power input of 4500.0 W is required to maintain the sphere at 3000.0 K. If heat conduction along the supports is ignored, what is the emissivity of the sphere? (no units) Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Answer x10

A thermal camera (LWIR) images a scene of rocks around a shallow pond just before sunrise. The measured brightness temperature of the pond is 305 K, while the brightness temperature of the rocks is 288 K. Assuming the kinetic temperatures of the pond and rocks are the same, estimate the emissivity of the rocks. Assume the emissivity of the water is 1.00. Report your answer to two significant digits (e.g. 0.12). What is the emissivity of the rocks?
The figure belows shows three components of an air-conditioning system, where T3 = 95°F and m3 = 1.5 lb/s. Refrigerant 134a flows through a throttling valve and a heat exchanger while air flows through a fan and the same heat exchanger. Data for steady-state operation are given on the figure. There is no significant heat transfer between any of the components and the surroundings. Kinetic and potential energy effects are negligible.

A small metal cube with a thermal mass mc and an initial temperature 0 is dropped into a container of water that is actively maintained at a constant temperature 0w. The cube quickly comes to rest on the bottom surface of the container. The bottom surface is maintained at a constant temperature 0 (note that this is different from 0w). The thermal resistance between the cube and the water is Rcw while the thermal resistance between the bottom surface of the container and the cube is RCB. The temperature of the cube is denoted by 0c. a) Draw the system schematic indicating the assumed directions of the heat transfer rates. Label all the nodes and system parameters. b) Derive the governing equation for the temperature of the cube, 0c. c) Where does to appear in the system schematic and how does it affect the governing equations? d) Calculate the steady-state temperature of the cube, css, assuming the following system parameters: 0o = 21°C, 0B = 6°C, 0w = 0°C, Rcw = 2°C/W, and RCB = 4°C/W

SANAE IV, a research station of The South African National Antarctic Programme (SANAP), is located on Vesleskarvet, Queen Maud Land. It uses an underground lake as the cold reservoir of a Carnot heat pump that maintains the temperature of a science lab at 302.8 K. To deposit 13488 J of heat in the lab, the heat pump requires 1022 J of work. Determine the temperature of water in the underground lake, in Kelvin
An object of mass 7.90 kg falls through a height of 40.0 m and, by means of a mechanical linkage, rotates a paddle wheel that stirs 0.620 kg of water. Assume that the initial gravitational potential energy of the object is fully transferred to thermal energy of the water, which is initially at 13.0°C. What is the temperature rise of the water?
A student living in a 4m x 6m x 6m dormitory room turns on her 150-W fan before he leaves the room on a summer day, hoping that the room will be cooler when she comes back in the evening. Assuming that all the doors and windows are tightly closed and disregarding any heat transfer through the walls and and the windows and he comes back 10 hours later, what is the initial pressure of the air in the room? Use specific heat values at room temperature (Cv=0.718 kJ/kg-K), and assume that the room to be at 15 deg C in the morning when he leaves and 58.1 deg C once he comes back. The molecular mass of the air is 29 g/mol.
