- B10Electronics and inhabitants of the International Space Station generate a significant amount of thermal energy that the station must get rid of. The only way that the station can exhaust thermal energy is by radiation, which it does using thin, 1.8-m-by-3.6-m panels that have a working temperature of about 6 °C and an emissivity of 0.85. Part A How much power is radiated from each panel? Assume that the panels are in the shade so that the absorbed radiation will be negligible. The temperature of deep space, which the panels face, is close to 0 K. Hint: Don't forget that the panels have two sides!

What is the final volume if the process is at constant pressure?Double-glazed windows are usually made of two glass panes with a thin layer of air sealed between the panes. a. Why do these windows reduce heat loss to a much greater extent than occurs if the double glazing is replaced by a thicker glass instead? b. Why does the insulating effect of the double glazing decrease if the two glass panes are too far apart? Explain.The basal metabolic rate is the rate at which energy is produced in the body when a person is at rest. A 68 kg (150 lb) person of height 1.83 m (6.0 ft) would have a body surface area of approximately 1.9 m². Part A What is the net amount of heat this person could radiate per second into a room at 19.0° C (about 66.2°F) if his skin's surface temperature is 31.0° C? (At such temperatures, nearly all the heat is infrared radiation, for which the body's emissivity is 1.0, regardless of the amount of pigment.) Express your answer in watts. ΑΣφ ?
