Solve: Reflect: The coefficient of volume expansion for the mercury is larger than for glass. When they are heated, both the volume of the mercury and the inside volume of the flask increase. But the increase for the mercury is greater and it no longer all fits inside the flask. 14.16. Set Up: Solve: (a) (b) 14.17. Set Up: at For aluminum, For brass, The distance between the marks at is Solve: Reflect: This section of both rulers increases in length, but the aluminum one increases more since its coefficient of linear expansion is greater. 14.18. Set Up: For water, For mercury, Solve: (a) (b) 14.19. Set Up: For aluminum, For iron, Solve: 14.20. Set Up: For water, Solve: (a) (b) 14.21. Set Up: 0.50 L of air has mass Solve: (a) (b) Reflect: Air has a small density, so one liter of air has little mass. But the specific heat capacity of air is rather large, larger than for most metals and about one-fourth the value for water. 14.22. Set Up:
