Q. A 3000 flask is initially open while in a room containing air at 1.00 and 20 . The flask is then closed and immersed in a bath of boiling water. When the air in the flask has reached thermodynamic equilibrium, the flask is opened and air is allowed to escape. The flask is then closed and cooled back to 20 .

Q. The burning of gasoline in a car releases about 3.0 × 104 kcal/gal. If a car averages 39 km/gal when driving 92 km/h, which requires 20 hp, what is the efficiency of the engine under those conditions?
