1. Figure P10.25 shows a circular steel casting with a gap. If the casting is heated, (a) does the width of the gap increase or decrease? (b) The gap width is 1.600 cm when the temperature is 30.0°C. Determine the gap width when the temperature is 190°C.
2. A hollow aluminium cylinder 20.0 cm deep has an internal capacity of 2.000 L at 20.0°C. It is completely filled with turpentine and then warmed to 80.0°C.
(a) How much turpentine overflows?
(b) If it is then cooled back to 20.0°C, how far below the surface of the cylinder’s rim is the turpentine surface?
