At a constant pressure of 0.905 atm, a chemical reaction takes place in a cylindrical container with a movable piston having a diameter of 40.0 cm. During the reaction, the height of the piston drop is by 65.0 cm. (The volume of a cylinder is V = ?r2h, where h is the height; 1 L·atm = 101.325 J.)
a. What is the change in volume in liters during the reaction?
b. What is the value in joules of the work ? done during the reaction?
