QUESTION 3 (20p). A piston cylinder system contains 3 moles of oxygen gas at 300K. The gas is compressed reversibly and isothermally from 0.06m$^3$ to 0.01 m$^3$. 850 J of work is given to the system for compression. Calculate the heat (in units of J) that needs to be removed from the system by accepting oxygen as a van der Waals fluid.

Suzy likes to drive with a silly sun ball on her car antenna. The frontal area of the ball is 0.004 m². As gas prices rise, her husband is concerned that she is wasting fuel because of the additional drag on the ball. He runs a quick test in the wind tunnel at his university and measures the drag coefficient to be 0.5 at nearly all air speeds. Estimate the heating value (kJ/kg) of fuel (with 2 decimal places) if 0.2 litres of fuel are wasted every year due to using this antenna. Use the following additional information: She drives about 15000 km per year at an average speed of 20 m/s. The overall car efficiency is 0.5. ($\rho$ fuel = 0.85 kg/L, $\rho$ air = 1.2 kg/m³, and $\mu$ = 1.8 × 10$^{-5}$ kg/ms).
