Chapter 17, Problem 78GP
A Melting Glacier (a) A glacier is made of ice of density 850 kg/m3 and is 92 m thick. Treating the glacial ice as if it were a liquid, what is the pressure at the bottom of the ice? (b) The water solid-liquid curve (Figure 17-21 (b)) near the bottom of the glacier can be approximated by P = (1.31 × 107) T + 1.01 × 105, where P is the pressure in Pa and T is the Celsius temperature. What is the melting-point temperature for water at the bottom of the glacier?

Problem 1: A certain rigid aluminum container contains a liquid at a gauge pressure of P0 = 2.02 × 105 Pa at sea level where the atmospheric pressure is Pa = 1.01 × 105 Pa. The volume of the container is V0 = 2.15 × 10-4 m3. The maximum difference between the pressure inside and outside that this particular container can withstand before bursting or imploding is ΔPmax = 2.41 × 105 Pa.For this problem, assume that the density of air maintains a constant value of ρa = 1.20 kg / m3 and that the density of seawater maintains a constant value of ρs = 1025 kg / m3.
