You are on a relaxing cruise in the warm waters of the Caribbean. All of a sudden, your yacht hits a reef and begins to go down. You and your friends start to pump up the little yellow life raft. You are all working in the shade of the sails, where it is cool. They say the raft should be blown up to its maximum volume. You, knowing about gas laws from chemistry, argue that it should only be blown up about 80% full. Explain, using gas law terms, why your option is the best.
