An aluminum can is filled to the brim with a liquid. The liquid and the can are heated thus their temperatures change by the equal amount. The can's initial volume at 5 °C is 6.7 ×10-4 m3. The coefficient of volume expansion for aluminum is 69 × 10-6 (C°)-1.When the liquid and the can are heated to 86 °C, 7.3 ×10-6 m3 of liquid spills over. Find the coefficient of volume expansion of the liquid?
