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 7 °C is 8.3 × 10^-4 m^3. The coefficient of volume expansion for aluminum is 69 × 10^-6 (°C)^-1. When the can and the liquid are heated to 79 °C, 4.5 × 10^-6 m^3 of liquid spills over. What is the coefficient of volume expansion of the liquid?
