A 25,000-kg subway train initially traveling at 10.5 m/s slows to a stop in a station and then stays there long enough for its brakes to cool. The station's dimensions are 67.0 m long by 18.5 m wide by 12.5 m high. Assuming all the work done by the brakes in stopping the train is transferred as heat uniformly to all the air in the station, by how much does the air temperature in the station rise? Take the density of the air to be 1.20 kg/m3 and its specific heat to be 1020 J/kg · K.
