Has the entropy of the aluminum bar decreased or increased?
A. Since the entropy change of a system is always positive, we can deduce that the entropy of the aluminum bar has increased.
B. Since the final lower temperature of the bar means lower average speed of molecular motion, we can deduce that the entropy of the bar has decreased.
C. We don't have enough information to determine whether the entropy of the aluminum bar has decreased or increased.

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.
