1. (10 points) A cylindrical gas piston has a diamcter of 40.0 cm and a total height of 100.0cm. The piston starts at a position 20.0cm from the top of the cylinder (position 1) and the pressure in the cylinder is 1.00atm at 25C. If the piston is completely withdrawn to a position at the bottom of the cylinder (position 2), calculate the pressure in the piston if the temperature of the cylinder remains constant
