The storage of radioactive waste is an important problem in the nuclear industry. One problem that scientists must take into account is volumetric expansion. Consider a 25.0 gallon metal canister of diameter 22.0 inches filled with a radioactive waste possessing a coefficient of volume expansion of 9.60 x 10-4 ('C)-'. This canister will be filled at room temperature (23.0 °C) and lowered deep into the Earth (where temperatures can reach 155 °C) for storage. If the coefficient of volume expansion of the metal is 4.10 x 10-5 (*C)-', how much waste will spill over the top if the lid becomes looOse? amount of waste: gallons
