At the surface pressure=1 atm
So, pressure at 50 km depth=(300X50) atm=15000 atm=1.519875 GPa
Temperature at the surface= 14℃
At 50 km depth temperature={(25X5)+14}℃=139℃
Using the attached phase diagram of stability of these phases, we can see that at these conditions only Jadeite+Quartz assemblage is stable. This condition has been plotted on the image.

3. (a) Do problem 5.40 in the text. Assume that the phase boundaries can be represented by straight lines. (b) The Earth's pressure gradient in the lithosphere is VP 300 atm/km (the temperature gradient can be taken from the previous question). At a depth of 50 km, will it be more likely that albite forms or that jadeite+quartz forms? Explain. Problem 5.40. The methods of this section can also be applied to reactions in which one set of solids converts...

Avalanche forecasters measure the temperature gradient , which is the rate at which the temperature in a snowpack T changes with respect to its depth h. A large temperature gradient may lead to a weak layer in the snowpack. When these weak layers collapse, avalanches occur. Avalanche forecasters use the rule of thumb that if exceeds 10°C/m anywhere in the snowpack, conditions are favorable for weak-layer formation, and the risk of avalanche increases. Assume the temperature function is continuous and...

P2) (50 pts.) The boiling temperature of nitrogen at atmospheric pressure at sea level (1 atm pressure) is -196°C. Therefore, nitrogen is commonly used in low-temperature scientific studies, since the temperature of liquid nitrogen in a tank open to the atmosphere will remain constant at -196°C until it is depleted. Any heat transfer to the tank will result in the evaporation of some liquid nitrogen, which has a heat of vaporization of 198 kJ/kg and a density of 810 kg/m3...

The pressure, P in atmospheres (atm), of an ideal gas can be expressed as a function of volume, V in liters (L), and temperature, T in kelvin (K), is P(V, T) = nRT/V where n = 1 mol and R 0.08 are constants. Suppose the current volume and temperature of a gas behaving according to the ideal gas law are: V = 5 L and T = 300 K. (a) Compute the differential (or, equivalently, approximate DeltaP) for the given...
