2. The interior of Josh's car has a volume of 5.0 m3. On a certain cold winter day, the temperature in the air outside is about 20F and the pressure is about 1 atm z 105 Pa. Josh parks his car outside with one window slightly open for some time, and after this period of time, the temperature and pressure in the air inside the car are the same as the temperature and pressure on the outside. josh then gets back into his car, rolls up the window, and turns the heater on to 72F. The car is electric and uses a heat pump as its heater. The heater has a coefcient of performance of approximately 3. The battery in the car has a capacity of about 65 kWh. Remember that 1 kWh = 103 x (1 Watt) x (1 hour). Roughly what fraction of the car's battery is consumed in heating its interior from 20F to 72F? You may make the simplifying assumption that the heating process is fast enough that no thermal energy in the interior air is lost to the outside during that process. You may also assume that the volume and number of moles of air in the car are constant during this process. Recall also that the gas constant has value R = 8.31]/ (mol K)
