(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?
