(a) The column of water that forms as a geyser erupts is 2100 m tall. What is the pressure at the bottom of the column of water?

(b) The water vapor-pressure curve (Figure 17-18) near the bottom of the column can be approximated by P = (1.86 × 105) T - 4.80 × 107, where P is the pressure in Pa and T is the Celsius temperature. What is the boiling-point temperature for water at the bottom of the column?
