(a) When cooled, the densities of most objects (1) increase, (2) decrease, (3) stay the same.
(b) By what percentage does the density of a bowling ball change (assuming it is a uniform sphere) when it is taken from room temperature (68oF) into the cold night air in Nome, Alaska (–40oF). Assume the ball is made out of a material that has a linear coefficient of expansion of 75.2 x 10-6/oC.
