At a foundry, 22 kg of molten aluminum witha temperature of 660.4◦C is poured into amold.If this is carried out in a room containing150 kg of air at 25◦C, what is the temperatureof the air after the aluminum is completelysolidified? Assume that the specific heat capacity of air is 1.0×10^3J/kg ·◦C. The specificheat of aluminum is 899 J/kg ·◦ C and its latent heat of fusion is 3.97 × 10^5J/kg.Answer in units of ◦C
A person driving to work saw his neighbor’s house with a broken front door. He called 911 to alert the police and have it checked. A crime detective then arrived at 9:00 AM at the house and discovered a dead body in the master’s bedroom. He evaluated the temperature of the body, and the result is 80.0 ℉. Afterwards, police started checking for a possible murder angle through evidence collection. One hour later, the temperature of the body is checked again, and the reading is 75.0 ℉. If the room temperature is 70-degree F, evaluate the time for which the possible murder case took place. Assume a normal body temperature of 98.6 ℉.

How many grams of ice at -13°C must be added to 711 grams of water that isinitially at a temperature of 87°C to produce water at a final temperature of10.0°C? Assume that no heat is lost to the surroundings and that the containerhas negligible mass. The specific heat of liquid water is 4190 J/kg • C° and ofice is 2050 J/kg • C°. For water the normal melting point is 0.00°C and the heatof fusion is 334 × 103 J/kg. The normal boiling point is 100°C and the heat ofvaporization is 2.26 × 106 J/kg.

Solar radiation is incident on a 5 m2 solar absorberplate surface at a rate of 800 W/m2. Ninety-three percent ofthe solar radiation is absorbed by the absorber plate, whilethe remaining 7 percent is reflected away. The solar absorberplate has a surface temperature of 40°C with an emissivityof 0.9 that experiences radiation exchange with the surroundingtemperature of -5°C. In addition, convective heat transferoccurs between the absorber plate surface and the ambientair of 20°C with a convection heat transfer coefficient of7 W/m2∙K. Determine the efficiency of the solar absorber,which is defined as the ratio of the usable heat collected bythe absorber to the incident solar radiation on the absorber.
What is the total rate of radiation of energy from a human body withsurface area 1.20 m2 and surface temperature 30°C = 303 K? If thesurroundings are at a temperature of 20°C, what is the net rate of radiativeheat loss from the body? The emissivity of the human body is veryclose to unity, irrespective of skin pigmentation.
Even when shut down after a period of normal use, a large commercial nuclear reactor transfers thermal energy at the rate of 150 MW by the radioactive decay of fission products. This heat transfer causes a rapid increase in temperature if the cooling system fails.(1 watt = 1 joule/second or 1 W = 1 J/s and 1 MW = 1 megawatt)(a) Calculate the rate of temperature increase in degreesCelsius per second (ºC/s) if the mass of the reactor core is 1.60×105 kg and it has an average specific heat of 0.3349 kJ/kgº ⋅ C . (b) How long would it take to obtain a temperature increase of 2000ºC , which could cause some metals holding the radioactive materials to melt? (The initial rate of temperature increase would be greater than thatcalculated here because the heat transfer is concentrated in a smaller mass. Later, however, the temperature increase would slow down because the 5×105-kg steel containment vessel would also begin to heat up.)
Estimate the rate at which heat can be conducted from theinterior of the body to the surface. As a model, assume thatthe thickness of tissue is 4.0 cm, that the skin is at 34°Cand the interior at 37°C, and that the surface area is 1.5m2Compare this to the measured value of about 230 W thatmust be dissipated by a person working lightly. This clearlyshows the necessity of convective cooling by the blood
