A method for resealing a partially full bottle of wine
Chapter 11, Problem 11.5(choose chapter or problem)
A method for resealing a partially full bottle of wine under a vacuum uses a specially designed rubber stopper to close the bottle. A simple pump is attached to the stopper, and to remove air from the bottle, the plunger of the pump is pulled up and then released. After about 15 pulland-release cycles the wine is under a partial vacuum. On the fifteenth pull-and-release cycle, does it require (a) more force, (b) less force, or (c) the same force to pull the plunger up than it did on the first cycle?
