Claxton prepares a plastic sheet to cover his pool on a hot summer morning. He covers the pool with a sheet of plastic that extends to the edges of the pool. He notices at the end of the day that the plastic sheet now goes 3 inches past the edge of the pool. Why has the size of the plastic sheet increased?
because the weight of the air caused the plastic to expand
because the heat of the sun caused the plastic to expand
because the lower air pressure caused the plastic to expand
because the higher air pressure caused the plastic to expand
