The air in a cylinder with a piston has a volume of 215 mL and a pressure of 625 mmHg. To obtain a higher pressure inside the cylinder at constant temperature, should the cylinder change as shown in A or B? Explain your choice in part (A). If the pressure inside the cylinder increases to 1.3 atm, what is the final volume of the cylinder? (The temperatue remains constant) Express your answer using two significant figures.
