Solve the following problems:

Problem 1) By what percentage does the density of a bowling ball change (assuming it is a uniform sphere) when it is taken from room temperature (68 µF) into the cold night air in Nome, Alaska (-40 µF). Assume the ball is made out of a material that has a linear coefficient of expansion of 6.85 × 105 µC.

Problem 2) If the diameter of the hole is 9.00cm at 20oC and the temperature of the oven is 200?C, what will be the new area of the hole?

Explain the each part of above problem in detail for help.
