A hollow aluminum cylinder 20.0 cm deep has an internal capacity of 2.000 L at 20.08C. It is completely filled with turpentine at 20.08C. The turpentine and the aluminum cylinder are then slowly warmed together to 80.08C. (a) How much turpentine overflows? (b) What is the volume of turpentine remaining in the cylinder at 80.08C? (c) If the combination with this amount of turpentine is then cooled back to 20.08C, how far below the cylinder’s rim does the turpentine’s surface recede?
