Based on this table and the description in Part I, did the driver’s behavior match his measured BAC of 0.12 percent? Explain. (1-2 sentences) If the driver had consumed only two beers as he claimed, what kind of behavior might he show? (1-2 sentences)
The legal limit for driving is 0.08 percent BAC. Can a driver show effects of impairment below this level? What effects might be present? Do you think it is safe to drive with these effects? Explain your answer. (2-3 sentences)

Air is held within a frictionless piston-cylinder container, which is oriented vertically. the mass of the piston is 0.45 kg and the cross-sectional area is 0.0030 m2. initially (state 1) the pressure of the gas is sufficient to support the weight of the piston as well as the force exerted by the atmospheric pressure ( 101.32 kpa). the volume occupied by the air within the cylinder in state 1 is 1.00 liter. one end of a spring (with spring constant k = 1000 n/m) is attached to the top of the piston, while the other end of the spring is attached to a stage that can move vertically. initially the spring is undeflected and therefore exerts no force. then the stage is then moved quasistatically downward a distance of 10.0 cm, at which point the system reaches state 2. the piston-cylinder is not insulated; rather it remains in diathermal contact with the surroundings, which are at a constant temperature of 300 k. what is the change of pressure within the container?
