Imagine you've been walking outside on a cold winter's day. When you arrive home at your studio apartment, you realize that you left a window open and your 5.0 m × 5.0 m × 3.0 m room is only slightly warmer than the outside. You turn on your 1.0-kW space heater right away and wait impatiently for the room to warm up. Part A How long will it be before the heater warms the air in the room by 10 °C? Express your answer in minutes to two significant figures. In this problem, make the following assumptions: • View Available Hint(s) • The entire 1.0 kW = 1.0 × 10³ J/s output of the space heater goes into warming the air in the room. • The air in the room is an ideal gas with five degrees of freedom per particle (three translational degrees of freedom and two rotational degrees of freedom-about right for nitrogen and охудen). • The air in the room is at a constant pressure of 1.00 atm. • At room temperature (22 °C= 295 K) and atmospheric pressure, 1.00 mole of air fills a volume of 24.2 L. time = minutes Submit Request Answer Provide Feedback This is slightly larger than the volume of air at standard temperature and pressure, because room temperature is hotter than 0 °C.

Electronics 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!
