An aluminum can is filled to the brim with a liquid. The can and the liquid are heated so their temperatures change by the same amount. The can’s initial volume at 15 ºC is 4.5×10- 4 m3 . The coefficient of volume expansion for aluminum is 69×10-6 ºC-1 . When the can and the liquid are heated to 75 ºC, 2.9×10-6 m3 of liquid spills over. What is the coefficient of volume expansion of the liquid?
