Which of the following is an example of a reversible process? a hand pump is rapidly compressed and the pressure and temperature in the pump rise. the pump is held in position as the temperature drops to the ambient temperature. a car engine burns fuel to produce motion of the car and exhausts the 140°c waste products of the combustion into the 20°c atmosphere. an ice cube at 0°c melts while in a water bath at 0°c. a stick of dynamite explodes. a high pressure air tank at room temperature has its valve opened and the gas in the tank rushes out until the pressure in the tank is equal to atmospheric pressure.

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
