When water boils in a pot with a loose lid, the increasedpressure forces the lid upward, releasing steam and reducing the pressurein the pot so that the lid drops back down. If the water continues toboil, the lid can rattle upward and downward. Consider a 1 L pot halffilled with boiling water. In this case there is half a liter, or 1/11.2 mol, ofair and steam above the water By multiplying the weight of the lid by the height of the jump, estimate the work done by the steam as the lid moves upward.
