I do not have the figures in your book.
the vapor pressure of the water = 1 atm + 120 kg * 9.8 if Newtons are used/(piston area)
A container is fitted with a movable piston of negligible mass and radius r = 0.061 m. Inside the container is liquid water in equilibrium with its vapor, as the drawing shows. The piston remains stationary with a 120-kg block on top of it. The air pressure acting on the top of the piston is one atmosphere. By using the vaporization curve for water in the figure below, find the temperature of the water.
