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

Question 10. A detective has been called to the scene of a crime where a dead body has just been discovered. The detective arrives at 9:00 AM and begins to investigate. Immediately, the temperature of the body is taken and is found to be 90.3°F. The detective checks the programmable thermostat and finds that the room has been kept at a constant 68.0°F for the past 3 days. After the evidence from the crime scene is collected, the temperature of the body is taken once more and found to be 89.0°F. This last temperature reading was taken exactly one hour after the first one. The following day, the detective is asked "At what time did our victim die?" Assuming that the victim's body temperature was normal (98.6°F) prior to death, what should the detective answer?

A typical coal-fired power plant burns 300 metric tons of coal every hour to generate 2.7 × 106 MJ of electric energy. 1 metric ton = 1000 kg; 1 metric ton of coal has a volume of 1.5 m3. The heat of combustion of coal is 28 MJ/kg. Assume that all heat is transferred from the fuel to the boiler and that all the work done in spinning the turbine is transformed into electric energy.a. Suppose the coal is piled up in a 10 m × 10 m room. How tall must the pile be to operate the plant for one day?b. What is the power plant’s efficiency?

Question 5 Specific Heat of Solid Substances Substance D Aluminum B silver; because it is a transition metal with the lowest specific heat value C Iron Copper Tin Given the specific heat information presented, which substance would make the BEST material to create a pan for cooking and why? D Specific Heat (J/kg°C) 899 443 385 213 Tin - because it has a low specific heat, which means it conducts heat the best. Aluminum - because it has a high specific heat, which means it conducts heat the best. Copper - because it has a mid-level specific heat, which means it is a good insulator. Iron - because it has a mid-level specific heat, which means it is a good conductor.
Assume that the normal human skin temperature is 308 K and that we emit thermal radiations. To estimate the surface area, consider human body as a cylinder with a height of 2m and a diameter of 0.5 m. What approximately is the power of the thermal radiation? (Note that this is not the net power because we also receiver the energy of thermal radiation of air at room temperature. 0.3W 50W 0.004 W 2000 W
